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 when traffic is IPSec protected.
|
Defaults
This command has no default settings.

Usage Guidelines
Allowing communication between same security interfaces 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.
You can also redirect incoming client VPN traffic back out through the same interface unencrypted as well as encrypted. If you send VPN traffic back out through the same interface unencrypted, you must enable NAT for the interface so that publicly routable addresses replace your private ip addresses (unless you already use public ip addresses in your local ip address pool). The following example commands apply an interface PAT rule to traffic sourced from the client ip pool:
hostname(config)#
ip local pool clientpool 192.168.0.10-192.168.0.100
hostname(config)# global (outside) 1 interface
hostname(config)# nat (outside) 1 192.168.0.0 255.255.255.0
When the security appliance sends encrypted VPN traffic back out this same interface, however, NAT is optional. To apply NAT to all outgoing traffic, implement only the commands above. To exempt the VPN-to-VPN traffic from NAT, add commands (to the example above) that implement NAT exemption for VPN-to-VPN traffic, such as:
hostname(config)#
access-list nonat permit ip 192.168.0.0 255.255.255.0 192.168.0.0
255.255.255.0
hostname(config)# nat (outside) 0 access-list nonat
See the nat command for more information.
Examples
The following example shows how to enable the same-security interface communication:
hostname(config)# same-security-traffic permit inter-interface

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.

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)#

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

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.

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

Usage Guidelines
The security appliance supports LDAP version 3 and is compatible with any LDAP v3 or v2 directory server. However, it supports password management features only on the Sun Microsystems JAVA System Directory Server and the Microsoft Active Directory. For example, the security appliance supports automated reset of an expired password without manual intervention by a system administrator with either a Sun or Microsoft LDAP server. With any other type of LDAP server, such as a Novell or OpenLDAP server, it supports all LDAP functions except for password management. Thus, if someone tries to log in to a security appliance using one of these other servers for authentication and their password has expired, the security appliance drops the connection and a manual password reset is required.

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. For more information, see the ldap-over-ssl command.
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

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. 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. 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. 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.

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.

set connection
To specify connection values within a policy-map for a traffic class, use the set connection command in class mode. Use this command to specify the maximum number of simultaneous connections and to specify whether TCP sequence number randomization is enabled. 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
|
(Optional) The maximum number of simultaneous TCP and/or UDP connections that are allowed.
|
disable
|
Turns off TCP sequence number randomization.
|
enable
|
Turns on TCP sequence number randomization.
|
embryonic-conn-max n
|
(Optional) The maximum number of simultaneous embryonic connections allowed.
|
per-client-embryonic- max n
|
(Optional) The maximum number of simultaneous embryonic connections allowed.
|
per-client-max n
|
(Optional) The maximum number of simultaneous connections allowed per client.
|
random-sequence- number
|
(Optional) Enable or disable TCP sequence number randomization. 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.
|
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.

The per-client-embryonic-max and per-client-max keywords were added.
|
Usage Guidelines
While the conn-max, embryonic-conn-max, per-client-embryonic-max, per-client-max, random-sequence-number keywords are all optional, you must specify at least one of them.
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
The set connection command parameters (conn-max, embryonic-conn-max, per-client-embryonic-max, per-client-max, random-sequence-number) can co-exist with any nat or static command; that is, you can configure connection parameters either through the nat/static commands using max-conn, emb_limit, or noramdomseq parameters, or through the MPC set connection command using conn-max, embryonic-conn-max, per-client-embryonic-max, per-client-max or random-sequence-number parameters. A mixed configuration is not recommended, but if one exists, it behaves in the following ways:
•
When a traffic class is subject to a connection limit or embryonic connection limit from both the MPC set connection command and the nat/static command, then whichever limit is reached, that limit is applied.
•
When a TCP traffic class is configured to have sequence number randomization disabled by either the MPC set connection command or the nat/static command, then sequence number randomization is disabled.
The per-client-embryonic-max and per-client-max parameters limit the maximum number of connections that a client can open. If particular clients use more network resources simultaneously than is desired, you can use these parameters to limit the number of connections that the security appliance will allow specific clients. DoS attacks seek to disrupt networks by overwhelming the capacity of key hosts with connections or requests for connections. You can use the per-client-embryonic-max and per-client-max parameters to thwart DoS attacks. After you configure a per-client maximum that can be supported by hosts likely to be attacked, malicious clients will be unable to overwhelm hosts on protected networks.
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
The following is an example of the use of the set connection command in a service policy that diverts traffic to a Cisco Content Security and Control (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

Usage Guidelines
You must have configured the policy-map command and the class command before issuing this command.
A TCP connection for which a three-way handshake is not complete is an embryonic connection. For the embryonic connection timeout value, use 0:0:0 to specify that the connection never times out. Otherwise, the timeout duration must be at least 5 seconds.
When the TCP connection is in the closing state, use the half-closed parameter to configure the length of time until the connection is freed. Use 0:0:0 to specify that the connection never times out. The minimum timeout duration is 5 minutes.
The tcp inactive connection timeout configures the period after which an idle TCP connection in the established state is disconnected. Use 0:0:0 to specify that the connection never times out. The minimum timeout duration is 5 minutes.
The reset keyword is used to send a TCP RST packet to both end systems once an idle TCP connection has timed out. Some applications require a TCP RST after a timeout to perform properly.
Examples
The following is an example of a set connection timeout command that specifies an embryonic connection timeout of two minutes:
hostname(config)# access-list http-server permit tcp any host 10.1.1.1
hostname(config)# class-map http-server
hostname(config-cmap)# match access-list http-server
hostname(config-cmap)# exit

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.

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:
hostname(config)# show activation-key
Serial Number: P3000000134 Running Activation Key: 0xyadayada 0xyadayada 0xyadayada
0xyadayada 0xyadayada
License Features for this Platform:
Maximum Physical Interfaces : Unlimited
Cut-through Proxy : Enabled
The flash activation key is the SAME as the running key.

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
