same-security-traffic

To permit communication between interfaces with equal security levels, or to allow traffic to enter and exit the same interface, use the same-security-traffic command in global configuration mode. To disable the same-security traffic, use the no form of this command.

same-security-traffic permit {inter-interface | intra-interface}

no same-security-traffic permit {inter-interface | intra-interface}

Syntax Description

inter-interface	Permits communication between different interfaces that have the same security level.
intra-interface	Permits communication in and out of the same interface.

Defaults

This command is disabled by default.

Command Modes

Command History

Release	Modification
7.0(1)(1)	This command was introduced.
7.2(1)	The intra-interface keyword now allows all traffic to enter and exit the same interface, and not just IPSec traffic.

Usage Guidelines

Allowing communication between same security interfaces (enabled by the same-security-traffic inter-interface command) provides the following benefits:

•You can configure more than 101 communicating interfaces. If you use different levels for each interface, you can configure only one interface per level (0 to 100).

•You can allow traffic to flow freely between all same security interfaces without access lists.

The same-security-traffic intra-interface command lets traffic enter and exit the same interface, which is normally not allowed. This feature might be useful for VPN traffic that enters an interface, but is then routed out the same interface. The VPN traffic might be unencrypted in this case, or it might be reencrypted for another VPN connection. For example, if you have a hub and spoke VPN network, where the security appliance is the hub, and remote VPN networks are spokes, for one spoke to communicate with another spoke, traffic must go into the security appliance and then out again to the other spoke.

Examples

The following example shows how to enable the same-security interface communication:

hostname(config)# same-security-traffic permit inter-interface

The following example shows how to enable traffic to enter and exit the same interface:

hostname(config)# same-security-traffic permit intra-interface

show running-config same-security-traffic	Displays the same-security-traffic configuration.

sasl-mechanism

To specify a SASL (Simple Authentication and Security Layer) mechanism for authenticating an LDAP client to an LDAP server, use the sasl-mechanism command in aaa-server host configuration mode. The SASL authentication mechanism options are digest-md5 and kerberos.

To disable an authentication mechanism, use the no form of this command.

sasl-mechanism {digest-md5 | kerberos server-group-name}

no sasl-mechanism {digest-md5 | kerberos server-group-name}

---

Note Because the security appliance serves as a client proxy to the LDAP server for VPN users, the LDAP client referred to here is the security appliance.

---

Syntax Description

Syntax DescriptionSyntax Description

digest-md5	The security appliance responds with an MD5 value computed from the username and password.
kerberos	The security appliance responds by sending the username and realm using the GSSAPI (Generic Security Services Application Programming Interface) Kerberos mechanism.
server-group-name	Specifies the Kerberos aaa-server group, up to 64 characters.

Defaults

No default behavior or values. The security appliance passes the authentication parameters to the LDAP server in plain text.

---

Note We recommend that you secure LDAP communications with SSL using the ldap-over-ssl command if you have not configured SASL.

Command History

Release	Modification
7.1(1)	This command was introduced.

Usage Guidelines

Use this command to specify security appliance authentication to an LDAP server using SASL mechanisms.

Both the security appliance and the LDAP server can support multiple SASL authentication mechanisms. When negotiating SASL authentication, the security appliance retrieves the list of SASL mechanisms configured on the server and sets the authentication mechanism to the strongest mechanism configured on both the security appliance and the server. The Kerberos mechanism is stronger than the Digest-MD5 mechanism. To illustrate, if both the LDAP server and the security appliance support both mechanisms, the security appliance selects Kerberos, the stronger of the mechanisms.

When disabling the SASL mechanisms, you must enter a separate no command for each mechanism you want to disable because they are configured independently. Mechanisms that you do not specifically disable remain in effect. For example, you must enter both of the following commands to disable both SASL mechanisms:

no sasl-mechanism digest-md5

no sasl-mechanism kerberos <server-group-name>

Examples

The following examples, entered in aaa-server host configuration mode, enable the SASL mechanisms for authentication to an LDAP server named ldapsvr1 with an IP address of 10.10.0.1. This example enables the SASL digest-md5 authentication mechanism:

hostname(config)# aaa-server ldapsvr1 protocol ldap

hostname(config-aaa-server-group)# aaa-server ldapsvr1 host 10.10.0.1

hostname(config-aaa-server-host)# sasl-mechanism digest-md5

hostname(config-aaa-server-host)#

The following example enables the SASL Kerberos authentication mechanism and specifies kerb-servr1 as the Kerberos AAA server:

hostname(config)# aaa-server ldapsvr1 protocol ldap

hostname(config-aaa-server-group)# aaa-server ldapsvr1 host 10.10.0.1

hostname(config-aaa-server-host)# sasl-mechanism kerberos kerbsvr1

hostname(config-aaa-server-host)#

secondary

To give the secondary unit higher priority in a failover group, use the secondary command in failover group configuration mode. To restore the default, use the no form of this command.

secondary

no secondary

Syntax Description

This command has no arguments or keywords.

Defaults

If primary or secondary is not specified for a failover group, the failover group defaults to primary.

Command Modes

				Context	System
Failover group configuration	•	•	—	—	•

Command History

Release	Modification
7.0(1)	This command was introduced.

Usage Guidelines

Assigning a primary or secondary priority to a failover group specifies which unit the failover group becomes active on when both units boot simulataneously (within a unit polltime). If one unit boots before the other, then both failover groups become active on that unit. When the other unit comes online, any failover groups that have the second unit as a priority do not become active on the second unit unless the failover group is configured with the preempt command or is manually forced to the other unit with the no failover active command.

Examples

The following example configures failover group 1 with the primary unit as the higher priority and failover group 2 with the secondary unit as the higher priority. Both failover groups are configured with the preempt command, so the groups will automatically become active on their preferred unit as the units become available.

hostname(config)# failover group 1 

hostname(config-fover-group)# primary

hostname(config-fover-group)# preempt 100

hostname(config-fover-group)# exit

hostname(config)# failover group 2

hostname(config-fover-group)# secondary

hostname(config-fover-group)# preempt 100

hostname(config-fover-group)# mac-address e1 0000.a000.a011 0000.a000.a012 

hostname(config-fover-group)# exit

hostname(config)#

Related Commands

Command	Description
failover group	Defines a failover group for Active/Active failover.
preempt	Forces the failover group to become active on its preferred unit when the unit becomes available.
primary	Gives the primary unit a higher priority than the secondary unit.

secondary-color

To set a secondary color for the WebVPN login, home page, and file access page, use the secondary-color command in webvpn mode. To remove a color from the configuration and reset the default, use the no form of this command.

secondary-color [color]

no secondary-color

Syntax Description

color

(Optional) Specifies the color. You can use a comma separated RGB value, an HTML color value, or the name of the color if recognized in HTML. •RGB format is 0,0,0, a range of decimal numbers from 0 to 255 for each color (red, green, blue); the comma separated entry indicates the level of intensity of each color to combine with the others. •HTML format is #000000, six digits in hexadecimal format; the first and second represent red, the third and fourth green, and the fifth and sixth represent blue. •Name length maximum is 32 characters

Defaults

The default secondary color is HTML #CCCCFF, a lavender shade.

secure-unit-authentication

To enable secure unit authentication, use the secure-unit-authentication enable command in group-policy configuration mode. To disable secure unit authentication, use the secure-unit-authentication disable command. To remove the secure unit authentication attribute from the running configuration, use the no form of this command. This option allows inheritance of a value for secure unit authentication from another group policy.

Secure unit authentication provides additional security by requiring VPN hardware clients to authenticate with a username and password each time the client initiates a tunnel. With this feature enabled, the hardware client does not have a saved username and password.

---

Note With this feature enabled, to bring up a VPN tunnel, a user must be present to enter the username and password.

---

secure-unit-authentication {enable | disable}

no secure-unit-authentication

Syntax Description

disable	Disables secure unit authentication.
enable	Enables secure unit authentication.

Defaults

Secure unit authentication is disabled.

Command Modes

Command History

Release	Modification
7.0(1)	This command was introduced.

Usage Guidelines

Secure unit authentication requires that you have an authentication server group configured for the tunnel group the hardware client(s) use.

If you require secure unit authentication on the primary security appliance, be sure to configure it on any backup servers as well.

Examples

The following example shows how to enable secure unit authentication for the group policy named FirstGroup:

hostname(config)# group-policy FirstGroup attributes

hostname(config-group-policy)# secure-unit-authentication enable

Related Commands

Command	Description
ip-phone-bypass	Lets IP phones connect without undergoing user authentication. Secure unit authentication remains in effect.
leap-bypass	Lets LEAP packets from wireless devices behind a VPN hardware client travel across a VPN tunnel prior to user authentication, when enabled. This lets workstations using Cisco wireless access point devices establish LEAP authentication. Then they authenticate again per user authentication.
user-authentication	Requires users behind a hardware client to identify themselves to the security appliance before connecting.

security-level

To set the security level of an interface, use the security-level command in interface configuration mode. To set the security level to the default, use the no form of this command. The security level protects higher security networks from lower security networks by imposing additional protection between the two.

security-level number

no security-level

Syntax Description

number

An integer between 0 (lowest) and 100 (highest).

Defaults

By default, the security level is 0.

If you name an interface "inside" and you do not set the security level explicitly, then the security appliance sets the security level to 100 (see the nameif command). You can change this level if desired.

Command Modes

The following table shows the modes in which you can enter the command:

Command Mode	Firewall Mode		Security Context
	Routed	Transparent	Single	Multiple
				Context	System
Interface configuration	•	•	•	•	—

Command History

Release	Modification
7.0(1)	This command was moved from a keyword of the nameif command to an interface configuration mode command.

Usage Guidelines

The level controls the following behavior:

•Network access—By default, there is an implicit permit from a higher security interface to a lower security interface (outbound). Hosts on the higher security interface can access any host on a lower security interface. You can limit access by applying an access list to the interface.

For same security interfaces, there is an implicit permit for interfaces to access other interfaces on the same security level or lower.

•Inspection engines—Some inspection engines are dependent on the security level. For same security interfaces, inspection engines apply to traffic in either direction.

–NetBIOS inspection engine—Applied only for outbound connections.

–OraServ inspection engine—If a control connection for the OraServ port exists between a pair of hosts, then only an inbound data connection is permitted through the security appliance.

•Filtering—HTTP(S) and FTP filtering applies only for outbound connections (from a higher level to a lower level).

For same security interfaces, you can filter traffic in either direction.

•NAT control—When you enable NAT control, you must configure NAT for hosts on a higher security interface (inside) when they access hosts on a lower security interface (outside).

Without NAT control, or for same security interfaces, you can choose to use NAT between any interface, or you can choose not to use NAT. Keep in mind that configuring NAT for an outside interface might require a special keyword.

•established command—This command allows return connections from a lower security host to a higher security host if there is already an established connection from the higher level host to the lower level host.

For same security interfaces, you can configure established commands for both directions.

Normally, interfaces on the same security level cannot communicate. If you want interfaces on the same security level to communicate, see the same-security-traffic command. You might want to assign two interfaces to the same level and allow them to communicate if you want to create more than 101 communicating interfaces, or you want protection features to be applied equally for traffic between two interfaces; for example, you have two departments that are equally secure.

If you change the security level of an interface, and you do not want to wait for existing connections to time out before the new security information is used, you can clear the connections using the clear local-host command.

Examples

The following example configures the security levels for two interfaces to be 100 and 0:

hostname(config)# interface gigabitethernet0/0

hostname(config-if)# nameif inside

hostname(config-if)# security-level 100

hostname(config-if)# ip address 10.1.1.1 255.255.255.0

hostname(config-if)# no shutdown

hostname(config-if)# interface gigabitethernet0/1

hostname(config-if)# nameif outside

hostname(config-if)# security-level 0

hostname(config-if)# ip address 10.1.2.1 255.255.255.0

hostname(config-if)# no shutdown

seq-past-window

To set the action for packets that have past-window sequence numbers (the sequence number of a received TCP packet is greater than the right edge of the TCP receiving window), use the seq-past-window command in tcp-map configuration mode. To set the value back to the default, use the no form of this command. This command is part of the TCP normalization policy enabled using the set connection advanced-options command.

seq-past-window {allow | drop}

no seq-past-window

Syntax Description

allow	Allows packets that have past-window sequence numbers. This action is only allowed if the queue-limit command is set to 0 (disabled).
drop	Drops packets that have past-window sequence numbers.

7.1(1)	This command was introduced.

Usage Guidelines

The security appliance supports LDAP version 3 and is compatible only with the Sun Microsystems JAVA System Directory Server and the Microsoft Active Directory.

---

Note•Sun—The DN configured on the security appliance to access a Sun directory server must be able to access the default password policy on that server. We recommend using the directory administrator, or a user with directory administrator privileges, as the DN. Alternatively, you can place an ACI on the default password policy.

•Microsoft—You must configure LDAP over SSL to enable password management with Microsoft Active Directory.

---

By default, the security appliance auto-detects whether it is connected to a Microsoft or a Sun LDAP directory server. However, if auto-detection fails to determine the LDAP server type and if you know the server is either a Microsoft or Sun server, you can use the server-type command to manually configure the server as either a Microsoft or a Sun Microsystems LDAP server.

Examples

The following example, entered in aaa-server host configuration mode, configures the server type for the LDAP server ldapsvr1 at IP address 10.10.0.1. The first example configures a Sun Microsystems LDAP server.

hostname(config)# aaa-server ldapsvr1 protocol ldap

hostname(config-aaa-server-group)# aaa-server ldapsvr1 host 10.10.0.1

hostname(config-aaa-server-host)# server-type sun

hostname(config-aaa-server-host)# 

The following example specifies that the security appliance use auto-detection to determine the server type:

hostname(config)# aaa-server ldapsvr1 protocol LDAP

hostname(config-aaa-server-group)# aaa-server ldapsvr1 host 10.10.0.1

hostname(config-aaa-server-host)# server-type auto-detect

service

To enable resets for denied TCP connections, use the service command in global configuration mode. To disable resets, use the no form of this command.

service {resetinbound [interface interface_name] | resetoutbound [interface interface_name] | resetoutside}

no service {resetinbound [interface interface_name] | resetoutbound [interface interface_name] | resetoutside}

Syntax Description

interface interface_name	Enables or disables resets for the specified interface.
resetinbound	Sends TCP resets for all inbound TCP sessions that attempt to transit the security appliance and are denied by the security appliance based on access lists or AAA settings. The security appliance also sends resets for packets that are allowed by an access list or AAA, but do not belong to an existing connection and are denied by the stateful firewall. Traffic between same security level interfaces is also affected. When this option is not enabled, the security appliance silently discards denied packets. If you do not specify an interface, then this setting applies to all interfaces.
resetoutbound	Sends TCP resets for all outbound TCP sessions that attempt to transit the security appliance and are denied by the security appliance based on access lists or AAA settings. The security appliance also sends resets for packets that are allowed by an access list or AAA, but do not belong to an existing connection and are denied by the stateful firewall. Traffic between same security level interfaces is also affected. When this option is not enabled, the security appliance silently discards denied packets. This option is enabled by default. You might want to disable outbound resets to reduce the CPU load during traffic storms, for example.
resetoutside	Enables resets for TCP packets that terminate at the least secure interface and are denied by the security appliance based on access lists or AAA settings. The security appliance also sends resets for packets that are allowed by an access list or AAA, but do not belong to an existing connection and are denied by the stateful firewall. When this option is not enabled, the security appliance silently discards the packets of denied packets. We recommend that you use the resetoutside keyword with interface PAT. This keyword allows the security appliance to terminate the IDENT from an external SMTP or FTP server. Actively resetting these connections avoids the 30-second timeout delay.

Defaults

By default, service resetoutbound is enabled for all interfaces.

Command History

Release	Modification
7.1(1)	The interface keyword and the resetoutbound command were added.

Usage Guidelines

You might want to explicitly send resets for inbound traffic if you need to reset identity request (IDENT) connections. When you send a TCP RST (reset flag in the TCP header) to the denied host, the RST stops the incoming IDENT process so that you do not have to wait for IDENT to time out. Waiting for IDENT to time out can cause traffic to slow because outside hosts keep retransmitting the SYN until the IDENT times out, so the service resetinbound command might improve performance.

Examples

The following example disables outbound resets for all interfaces except for the inside interface:

hostname(config)# no service resetoutbound

hostname(config)# service resetoutbound interface inside

The following example enables inbound resets for all interfaces except for the DMZ interface:

hostname(config)# service resetinbound

hostname(config)# no service resetinbound interface dmz

The following example enables resets for connections that terminate on the outside interface:

hostname(config)# service resetoutside

Usage Guidelines

On the ASA 5500 series adaptive security appliance, if you forget the passwords, you can boot the security appliance into ROMMON by pressing the Escape key on the terminal keyboard when prompted during startup. Then set the security appliance to ignore the startup configuration by changing the configuration register (see the config-register command). For example if your configuration register is the default 0x1, then change the value to 0x41 by entering the confreg 0x41 command. After reloading the security appliance, it loads a default configuration, and you can enter privileged EXEC mode using the default passwords. Then load the startup configuration by copying it to the running configuration and reset the passwords. Finally, set the security appliance to boot as before by setting the configuration register to the original setting. For example, enter the config-register 0x1 command in global configuration mode.

On the PIX 500 series security appliance, boot the security appliance into monitor mode by pressing the Escape key on the terminal keyboard when prompted during startup. Then download the PIX password tool to the security appliance, which erases all passwords and aaa authentication commands.

On the ASA 5500 series adaptive security appliance, the no service password-recovery command prevents a user from entering ROMMON with the configuration intact. When a user enters ROMMON, the security appliance prompts the user to erase all Flash file systems. The user cannot enter ROMMON without first performing this erasure. If a user chooses not to erase the Flash file system, the security appliance reloads. Because password recovery depends on using ROMMON and maintaining the existing configuration, this erasure prevents you from recovering a password. However, disabling password recovery prevents unauthorized users from viewing the configuration or inserting different passwords. In this case, to recover the system to an operating state, load a new image and a backup configuration file, if available. The service password-recovery command appears in the configuration file for informational purposes only; when you enter the command at the CLI prompt, the setting is saved in NVRAM. The only way to change the setting is to enter the command at the CLI prompt. Loading a new configuration with a different version of the command does not change the setting. If you disable password recovery when the security appliance is configured to ignore the startup configuration at startup (in preparation for password recovery), then the security appliance changes the setting to boot the startup configuration as usual. If you use failover, and the standby unit is configured to ignore the startup configuration, then the same change is made to the configuration register when the no service password recovery command replicates to the standby unit.

On the PIX 500 series security appliance, the no service password-recovery command forces the PIX password tool to prompt the user to erase all Flash file systems. The user cannot use the PIX password tool without first performing this erasure. If a user chooses not to erase the Flash file system, the security appliance reloads. Because password recovery depends on maintaining the existing configuration, this erasure prevents you from recovering a password. However, disabling password recovery prevents unauthorized users from viewing the configuration or inserting different passwords. In this case, to recover the system to an operating state, load a new image and a backup configuration file, if available.

Examples

The following example disables password recovery for the ASA 5500 series adaptive security appliance:

hostname(config)# no service password-recovery

WARNING: Executing "no service password-recovery" has disabled the password recovery 
mechanism and disabled access to ROMMON.  The only means of recovering from lost or 
forgotten passwords will be for ROMMON to erase all file systems including configuration 
files and images.  You should make a backup of your configuration and have a mechanism to 
restore images from the ROMMON command line.

The following example disables password recovery for the PIX 500 series security appliance:

hostname(config)# no service password-recovery

WARNING: Saving "no service password-recovery" in the startup-config will disable password 
recovery via the npdisk application.  The only means of recovering from lost or forgotten 
passwords will be for npdisk to erase all file systems including configuration files and 
images.  You should make a backup of your configuration and have a mechanism to restore 
images from the Monitor Mode command line.

The following example for the ASA 5500 series adaptive security appliance shows when to enter ROMMON at startup and how to complete a password recovery operation.

Use BREAK or ESC to interrupt boot.

Use SPACE to begin boot immediately.

service-policy (class)

To apply a hierarchical policy map under another policy map, use the service-policy command in class configuration mode. To disable the service policy, use the no form of this command. Hierarchical policies are supported only for QoS traffic shaping when you want to perform priority queueing on a subset of shaped traffic.

service-policy policymap_name

no service-policy policymap_name

Syntax Description

policymap_name

Specifies the policy map name that you configured in the policy-map command. You can only specify a Layer 3/4 policy map that includes the priority command.

Defaults

No default behavior or values.

	Routed	Transparent	Single	Multiple
				Context	System
Class configuration	•	•	•	•	—

Command History

Release	Modification
7.2(4)	This command was introduced.

Usage Guidelines

Hierarchical priority queueing is used on interfaces on which you enable a traffic shaping queue. A subset of the shaped traffic can be prioritized. The standard priority queue is not used (the priority-queue command).

For hierarchical priority-queueing, perform the following tasks using Modular Policy Framework:

1. class-map—Identify the traffic on which you want to perform priority queueing.

2. policy-map (for priority queueing)—Identify the actions associated with each class map.

a. class—Identify the class map on which you want to perform actions.

b. priority—Enable priority queueing for the class map. You can only include the priority command in this policy map if you want to use is hierarchically.

3. policy-map (for traffic shaping)—Identify the actions associated with the class-default class map.

a. class class-default—Identify the class-default class map on which you want to perform actions.

b. shape—Apply traffic shaping to the class map.

c. service-policy—Call the priority queueing policy map in which you configured the priority command so you can apply priority queueing to a subset of shaped traffic.

4. service-policy—Assigns the policy map to an interface or globally.

Examples

The following example enables traffic shaping for all traffic on the outside interface, and prioritizes traffic within VPN tunnel-grp1 with the DSCP bit set to ef:

hostname(config)# class-map TG1-voice

hostname(config-cmap)# match tunnel-group tunnel-grp1

hostname(config-cmap)# match dscp ef

hostname(config)# policy-map priority-sub-policy

hostname(config-pmap)# class TG1-voice

hostname(config-pmap-c)# priority

hostname(config-pmap-c)# policy-map shape_policy

hostname(config-pmap)# class class-default

hostname(config-pmap-c)# shape

hostname(config-pmap-c)# service-policy priority-sub-policy

hostname(config-pmap-c)# service-policy shape_policy interface outside

service-policy (global)

To activate a policy map globally on all interfaces or on a targeted interface, use the service-policy command in global configuration mode. To disable the service policy, use the no form of this command. Use the service-policy command to enable a set of policies on an interface.

service-policy policymap_name [ global | interface intf ]

no service-policy policymap_name [ global | interface intf ]

Syntax Description

policymap_name	Specifies the policy map name that you configured in the policy-map command. You can only specify a Layer 3/4 policy map, and not an inspection policy map (policy-map type inspect).
global	Applies the policy map to all interfaces.
interface intf	Applies the policy map to a specific interface.

Defaults

Command History

Release	Modification
7.0(1)	This command was introduced.

Usage Guidelines

To enable the service policy, use the Modular Policy Framework:

1. class-map—Identify the traffic on which you want to perform priority queueing.

2. policy-map—Identify the actions associated with each class map.

a. class—Identify the class map on which you want to perform actions.

b. commands for supported features—For a given class map, you can configure many actions for various features, including QoS, application inspection, CSC or AIP SSM, TCP and UDP connections limits and timeout, and TCP normalization. See the Cisco Security Appliance Command Line Configuration Guide for more details about the commands available for each feature.

3. service-policy—Assigns the policy map to an interface or globally.

Interface service policies take precedence over the global service policy for a given feature. For example, if you have a global policy with inspections, and an interface policy with TCP normalization, then both inspections and TCP normalization are applied to the interface. However, if you have a global policy with inspections, and an interface policy with inspections, then only the interface policy inspections are applied to that interface.

By default, the configuration includes a global policy that matches all default application inspection traffic and applies inspection to the traffic globally. You can only apply one global policy, so if you want to alter the global policy, you need to either edit the default policy or disable it and apply a new one.

The default service policy includes the following command:

service-policy global_policy global

Examples

The following example shows how to enable the inbound_policy policy map on the outside interface:

hostname(config)# service-policy inbound_policy interface outside

The following commands disable the default global policy, and enables a new one called new_global_policy on all other security appliance interfaces:

hostname(config)# no service-policy global_policy global

hostname(config)# service-policy new_global_policy global

set connection

To specify connection limits within a policy map for a traffic class, use the set connection command in class configuration mode. To remove these specifications, thereby allowing unlimited connections, use the no form of this command.

set connection {[conn-max n] [embryonic-conn-max n] [per-client-embryonic-max n] [per-client-max n] [random-sequence-number {enable | disable}]}

no set connection {[conn-max n] [embryonic-conn-max n] [per-client-embryonic-max n] [per-client-max n] [random-sequence-number {enable | disable}]}

Syntax Description

conn-max n	The maximum number of simultaneous TCP and/or UDP connections that are allowed, between 0 and 65535. The default is 0, which allows unlimited connections. For example, if two servers are configured to allow simultaneous TCP and/or UDP connections, the connection limit is applied to each configured server separately.
embryonic-conn-max n	The maximum number of simultaneous embryonic connections allowed, between 0 and 65535. The default is 0, which allows unlimited connections.
per-client-embryonic-max n	Sets the maximum number of simultaneous embryonic connections allowed per client, between 0 and 65535. A client is defined as the host that sends the initial packet of a connection (that builds the new connection) through the security appliance. If an access-list is used with a class-map to match traffic for this feature, the embryonic limit is applied per-host, and not the cumulative embryonic connections of all clients that match the access list. The default is 0, which allows unlimited connections. This keyword is not available for management class maps.
per-client-max n	Sets the maximum number of simultaneous connections allowed per client, between 0 and 65535. A client is defined as the host that sends the initial packet of a connection (that builds the new connection) through the security appliance. If an access-list is used with a class-map to match traffic for this feature, the connection limit is applied per-host, and not the cumulative connections of all clients that match the access list. The default is 0, which allows unlimited connections. This keyword is not available for management class maps.
random-sequence-number {enable | disable}	Enable or disable TCP sequence number randomization. This keyword is not available for management class maps. See the "Usage Guidelines" section for more information.

Defaults

For the conn-max, embryonic-conn-max, per-client-embryonic-max, and per-client-max parameters, the default value of n is 0, which allows unlimited connections.

Sequence number randomization is enabled by default.

7.0(1)	This command was introduced.
7.1(1)	The per-client-embryonic-max and per-client-max keywords were added.

Usage Guidelines

Configure this command using Modular Policy Framework. First define the traffic to which you want to apply the timeout using the class-map command (for through traffic) or class-map type management command (for management traffic). Then enter the policy-map command to define the policy, and enter the class command to reference the class map. In class configuration mode, you can enter the set connection command. Finally, apply the policy map to an interface using the service-policy command. For more information about how Modular Policy Framework works, see the Cisco Security Appliance Command Line Configuration Guide.

---

Note You can also configure maximum connections, maximum embryonic connections, and TCP sequence randomization in the NAT configuration. If you configure these settings for the same traffic using both methods, then the security appliance uses the lower limit. For TCP sequence randomization, if it is disabled using either method, then the security appliance disables TCP sequence randomization.

---

TCP Intercept Overview

Limiting the number of embryonic connections protects you from a DoS attack. The security appliance uses the per-client limits and the embryonic connection limit to trigger TCP Intercept, which protects inside systems from a DoS attack perpetrated by flooding an interface with TCP SYN packets. An embryonic connection is a connection request that has not finished the necessary handshake between source and destination. TCP Intercept uses the SYN cookies algorithm to prevent TCP SYN-flooding attacks. A SYN-flooding attack consists of a series of SYN packets usually originating from spoofed IP addresses. The constant flood of SYN packets keeps the server SYN queue full, which prevents it from servicing connection requests. When the embryonic connection threshold of a connection is crossed, the security appliance acts as a proxy for the server and generates a SYN-ACK response to the client SYN request. When the security appliance receives an ACK back from the client, it can then authenticate the client and allow the connection to the server.

Disabling TCP Intercept for Management Packets for Clientless SSL Compatibility

By default, TCP management connections have TCP Intercept always enabled. When TCP Intercept is enabled, it intercepts the 3-way TCP connection establishment handshake packets and thus deprives the security appliance from processing the packets for clientless SSL. Clientless SSL requires the ability to process the 3-way handshake packets to provide selective ACK and other TCP options for clientless SSL connections. To disable TCP Intercept for management traffic, you can set the embryonic connection limit; only after the embryonic connection limit is reached is TCP Intercept enabled.

TCP Sequence Randomization Overview

Each TCP connection has two ISNs: one generated by the client and one generated by the server. The security appliance randomizes the ISN of the TCP SYN passing in both the inbound and outbound directions.

Randomizing the ISN of the protected host prevents an attacker from predecting the next ISN for a new connection and potentially hijacking the new session.

TCP initial sequence number randomization can be disabled if required. For example:

•If another in-line firewall is also randomizing the initial sequence numbers, there is no need for both firewalls to be performing this action, even though this action does not affect the traffic.

•If you use eBGP multi-hop through the security appliance, and the eBGP peers are using MD5. Randomization breaks the MD5 checksum.

•You use a WAAS device that requires the security appliance not to randomize the sequence numbers of connections.

Examples

The following is an example of the use of the set connection command configure the maximum number of simultaneous connections as 256 and to disable TCP sequence number randomization:

hostname(config)# policy-map localpolicy1

hostname(config-pmap)# class local_server

hostname(config-pmap-c)# set connection conn-max 256 random-sequence-number disable

hostname(config-pmap-c)# 

The following is an example of the use of the set connection command in a service policy that diverts traffic to a CSC SSM. The set connection command restricts each client whose traffic the CSC SSM scans to a maximum of five connections.

hostname(config)# policy-map csc_policy

hostname(config-pmap)# class local_server

hostname(config-pmap-c)# set connection per-client-max 5

hostname(config-pmap-c)# csc fail-close

hostname(config-pmap-c)# 

You can enter this command with multiple parameters or you can enter each parameter as a separate command. The security appliance combines the commands into one line in the running configuration. For example, if you entered the following two commands in class configuration mode:

hostname(config-pmap-c)# set connection conn-max 600

hostname(config-pmap-c)# set connection embryonic-conn-max 50

The output of the show running-config policy-map command would display the result of the two commands in a single, combined command:

set connection conn-max 600 embryonic-conn-max 50

set connection timeout

To specify connection timeouts within a policy map for a traffic class, use the set connection timeout command in class configuration mode. To remove the timeout, use the no form of this command.

set connection timeout {[embryonic hh:mm:ss] [tcp hh:mm:ss [reset]] [half-closed hh:mm:ss] [dcd [retry_interval [max_retries]]]}

no set connection timeout {[embryonic hh:mm:ss] [tcp hh:mm:ss [reset]] [half-closed hh:mm:ss] [dcd [retry_interval [max_retries]]]}

Syntax Description

dcd	Enables dead connection detection (DCD). DCD detects a dead connection and allows it to expire, without expiring connections that can still handle traffic. You configure DCD when you want idle, but valid connections to persist. After a TCP connection times out, the security appliance sends DCD probes to the end hosts to determine the validity of the connection. If one of the end hosts fails to respond after the maximum retries are exhausted, the security appliance frees the connection. If both end hosts respond that the connection is valid, the security appliance updates the activity timeout to the current time and reschedules the idle timeout accordingly.
embryonic hh:mm:ss	Sets the timeout period until a TCP embryonic (half-open) connection is closed, between 0:0:5 and 1193:0:0. The default is 0:0:30. You can also set the value to 0, which means the connection never times out. A TCP connection for which a three-way handshake is not complete is an embryonic connection.
half-closed hh:mm:ss	Sets the idle timeout period until a half-closed connection is closed, between 0:5:0 and 1193:0:0. The default is 0:10:0. You can also set the value to 0, which means the connection never times out. Half-closed connections are not affected by DCD. Also, the security appliance does not send a reset when taking down half-closed connections.
max_retries	Sets the number of consecutive failed retries for DCD before declaring the connection as dead. The minimum value is 1 and the maximum value is 255. The default is 5.
reset	Sends a TCP RST packet to both end systems after TCP idle connections are removed.
retry_interval	Time duration in hh:mm:ss format to wait after each unresponsive DCD probe before sending another probe, between 0:0:1 and 24:0:0. The default is 0:0:15.
tcp hh:mm:ss	Sets the idle timeout period after which an established connection closes.

Defaults

The default embryonic timeout is 30 seconds.

The default half-closed idle timeout is 10 minutes.

The default dcd max_retries value is 5.

The default dcd retry_interval value is 15 seconds.

The default tcp idle timeout is 1 hour.

Usage Guidelines

Configure this command using Modular Policy Framework. First define the traffic to which you want to apply the timeout using the class-map command. Then enter the policy-map command to define the policy, and enter the class command to reference the class map. In class configuration mode, you can enter the set connection timeout command. Finally, apply the policy map to an interface using the service-policy command. For more information about how Modular Policy Framework works, see the Cisco Security Appliance Command Line Configuration Guide.

Enabling DCD changes the behavior of idle-timeout handling in the TCP normalizer. DCD probing resets the idle timeout on the connections seen in the show conn command. To determine when a connection that has exceeded the configured timeout value in the timeout command but is kept alive due to DCD probing, the show service-policy command includes counters to show the amount of activity from DCD.

Examples

The following example sets the connection timeouts for all traffic:

hostname(config)# class-map CONNS

hostname(config-cmap)# match any

hostname(config-cmap)# policy-map CONNS

hostname(config-pmap)# class CONNS

hostname(config-pmap-c)# set connection timeout tcp 2:0:0 embryonic 0:40:0 half-closed 
0:20:0 dcd

hostname(config-pmap-c)# service-policy CONNS interface outside

You can enter set connection commands with multiple parameters or you can enter each parameter as a separate command. The security appliance combines the commands into one line in the running configuration. For example, if you entered the following two commands in class configuration mode:

hostname(config-pmap-c)# set connection timeout tcp 2:0:0

hostname(config-pmap-c)# set connection timeout embryonic 0:40:0

the output of the show running-config policy-map command would display the result of the two commands in a single, combined command:

set connection timeout tcp 2:0:0 embryonic 0:40:0

Usage Guidelines

The setup dialog automatically appears at boot time if there is no startup configuration in Flash memory.

Before you can use the setup command, you must have an inside interface already configured. The PIX 500 series default configuration includes an inside interface (Ethernet 1), but the ASA 550 series default configuration does not. Before using the setup command, enter the interface command for the interface you want to make inside, and then the nameif inside command.

In multiple context mode, you can use the setup command in the system execution space and for each context.

When you enter the setup command, you are asked for the information in Table 24-1. The system setup command includes a subset of these prompts. If there is already a configuration for the prompted parameter, it appears in barckets so you can either accept it as the default or override it by entering something new.

Table 24-1 Setup Prompts

shape

To enable QoS traffic shaping, use the shape command in class configuration mode. If you have a device that transmits packets at a high speed, such as a security appliance with Fast Ethernet, and it is connected to a low speed device such as a cable modem, then the cable modem is a bottleneck at which packets are frequently dropped. To manage networks with differing line speeds, you can configure the security appliance to transmit packets at a fixed slower rate, called traffic shaping. To remove this configuration, use the no form of this command.

shape average rate [burst_size]

no shape average rate [burst_size]

Syntax Description

average rate	Sets the average rate of traffic in bits per second over a given fixed time period, between 64000 and 154400000. Specify a value that is a multiple of 8000. See the "Usage Guidelines" section for more information about how the time period is calculated.
burst_size	Sets the average burst size in bits that can be transmitted over a given fixed time period, between 2048 and 154400000. Specify a value that is a multiple of 128. If you do not specify the burst_size, the default value is equivalent to 4-milliseconds of traffic at the specified average rate. For example, if the average rate is 1000000 bits per second, 4 ms worth = 1000000 * 4/1000 = 4000.

Defaults

If you do not specify the burst_size, the default value is equivalent to 4-milliseconds of traffic at the specified average rate. For example, if the average rate is 1000000 bits per second, 4 ms worth = 1000000 * 4/1000 = 4000.

Command History

7.2(4)	This command was introduced.

Usage Guidelines

To enable traffic shaping, use the Modular Policy Framework:

1. policy-map—Identify the actions associated with the class-default class map.

a. class class-default—Identify the class-default class map on which you want to perform actions.

b. shape—Apply traffic shaping to the class map.

c. (Optional) service-policy—Call a different policy map in which you configured the priority command so you can apply priority queueing to a subset of shaped traffic.

2. service-policy—Assigns the policy map to an interface or globally.

Traffic Shaping Overview

Traffic shaping is used to match device and link speeds, thereby controlling packet loss, variable delay, and link saturation, which can cause jitter and delay.

•Traffic shaping must be applied to all outgoing traffic on a physical interface or in the case of the ASA 5505, on a VLAN. You cannot configure traffic shaping for specific types of traffic.

•Traffic shaping is implemented when packets are ready to be transmitted on an interface, so the rate calculation is performed based on the actual size of a packet to be transmitted, including all the possible overhead such as the IPSec header and L2 header.

•The shaped traffic includes both through-the-box and from-the-box traffic.

•The shape rate calculation is based on the standard token bucket algorithm. The token bucket size is twice the burst size value. See the Cisco Security Appliance Command Line Configuration Guide for more information about the token bucket.

•When bursty traffic exceeds the specified shape rate, packets are queued and transmitted later. Following are some characteristics regarding the shape queue (for information about hierarchical priority queueing, see the priority command):

–The queue size is calculated based on the shape rate. The queue can hold the equivalent of 200-milliseconds worth of shape rate traffic, assuming a 1500-byte packet. The minimum queue size is 64.

–When the queue limit is reached, packets are tail-dropped.

–Certain critical keep-alive packets such as OSPF Hello packets are never dropped.

–The time interval is derived by time_interval = burst_size / average_rate. The larger the time interval is, the burstier the shaped traffic might be, and the longer the link might be idle. The effect can be best understood using the following exaggerated example:

Average Rate = 1000000

Burst Size = 1000000

In the above example, the time interval is 1 second, which means, 1 Mbps of traffic can be bursted out within the first 10 milliseconds of the 1-second interval on a 100 Mbps FE link and leave the remaining 990 milliseconds idle without being able to send any packets until the next time interval. So if there is delay-sensitive traffic such as voice traffic, the Burst Size should be reduced compared to the average rate so the time interval is reduced.

How QoS Features Interact

You can configure each of the QoS features alone if desired for the security appliance. Often, though, you configure multiple QoS features on the security appliance so you can prioritize some traffic, for example, and prevent other traffic from causing bandwidth problems.

See the following supported feature combinations per interface:

•Standard priority queuing (for specific traffic) + Policing (for the rest of the traffic).

You cannot configure priority queueing and policing for the same set of traffic.

•Traffic shaping (for all traffic on an interface) + Hierarchical priority queueing (for a subset of traffic).

You cannot configure traffic shaping and standard priority queueing for the same interface; only hierarchical priority queueing is allowed. For example, if you configure standard priority queueing for the global policy, and then configure traffic shaping for a specific interface, the feature you configured last is rejected because the global policy overlaps the interface policy.

Typically, if you enable traffic shaping, you do not also enable policing for the same traffic, although the security appliance does not restrict you from configuring this.

Examples

The following example enables traffic shaping for all traffic on the outside interface, and prioritizes traffic within VPN tunnel-grp1 with the DSCP bit set to ef:

hostname(config)# class-map TG1-voice

hostname(config-cmap)# match tunnel-group tunnel-grp1

hostname(config-cmap)# match dscp ef

hostname(config)# policy-map priority-sub-policy

hostname(config-pmap)# class TG1-voice

hostname(config-pmap-c)# priority

hostname(config-pmap-c)# policy-map shape_policy

hostname(config-pmap)# class class-default

hostname(config-pmap-c)# shape

hostname(config-pmap-c)# service-policy priority-sub-policy

hostname(config-pmap-c)# service-policy shape_policy interface outside

Command History

Release	Modification
PIX Version 7.0	Support for this command was introduced on the security appliance.

Usage Guidelines

The show activation-key command output indicates the status of the activation key as follows:

•If the activation key in the security appliance Flash file system is the same as the activation key running on the security appliance, then the show activation-key output reads as follows:

The flash activation key is the SAME as the running key.

•If the activation key in the security appliance Flash file system is different from the activation key running on the security appliance, then the show activation-key output reads as follows:

The flash activation key is DIFFERENT from the running key.

The flash activation key takes effect after the next reload.

•If you downgrade your activation key, the display shows that the running key (the old key) differs from the key that is stored in the Flash (the new key). When you restart, the security appliance uses the new key.

•If you upgrade your key to enable extra features, the new key starts running immediately without a restart.

•For the PIX Firewall platform, if there is any change in the failover feature (R/UR/FO) between the new key and the oldkey, it prompts for confimation. If the user enters n, it aborts the change; otherwise it updates the key in the Flash file system. When you restart the security appliance uses the new key.

Examples

This example shows how to display the commands in the configuration for features that are enabled by your activation key:

Command History

Release	Modification
7.0(1)	This command was introduced.

Usage Guidelines

Each active ASDM session has one or more associated ASDM logging sessions. ASDM uses the logging session to retrieve syslog messages from the security appliance. Each ASDM logging session is assigned a unique session ID. You can use this session ID with the asdm disconnect log_session command to terminate the specified session.

---

Note Because each ASDM session has at least one ASDM logging session, the output for the show asdm sessions and show asdm log_sessions may appear to be the same.

---

Examples

The following is sample output from the show asdm log_sessions command:

hostname# show asdm log_sessions

0 192.168.1.1

1 192.168.1.2
