•Cisco ASA 5500 series adaptive security appliance, Version 8.0(4)

•ASDM, Version 6.1(3)

Cisco ASA 5500 Series Adaptive Security Appliance

The Cisco ASA 5500 series adaptive security appliances are purpose-built solutions that combine the most effective security and VPN services with the innovative Cisco Adaptive Identification and Mitigation (AIM) architecture.

Designed as a key component of the Cisco Self-Defending Network, the adaptive security appliance provides proactive threat defense that stops attacks before they spread through the network, controls network activity and application traffic, and delivers flexible VPN connectivity. The result is a powerful multifunction network adaptive security appliance family that provides the security breadth and depth for protecting small and medium-sized business and enterprise networks while reducing the overall deployment and operations costs and complexities associated with providing this new level of security.

For more information on all of the new features, see New Features.

Additionally, the adaptive security appliance software supports Cisco Adaptive Security Device Manager (ASDM). ASDM delivers world-class security management and monitoring through an intuitive, easy-to-use web-based management interface. Bundled with the adaptive security appliance, ASDM accelerates adaptive security appliance deployment with intelligent wizards, robust administration tools, and versatile monitoring services that complement the advanced integrated security and networking features offered by the market-leading suite of the adaptive security appliance. Its secure, web-based design enables anytime, anywhere access to adaptive security appliances. For more information on ASDM, see the Cisco ASDM Release Notes Version 6.1(3).

Important Notes

•ASA Compatible with EIGRP Version 3—EIGRP support was added in Version 8.0(2). However, due to a packet format change, Version 8.0(3) and later are not compatible with Version 8.0(2). Therefore, if you upgrade an adaptive security appliance to Version 8.0(3) or later, and it is peering with another adaptive security appliance running Version 8.0(2), then the peer must also be upgraded, or EIGRP will not operate correctly.

•Show Active Directory Groups—The DAP Usability feature, used to list active directory groups, is for ASDM only. The show ad-groups command is not intended for CLI use.

•IPSec VPN packets are dropped when compression is enabled—When you configure the ip-comp enable command under the group-policy, then large packets that are eligible for compression are silently dropped by the security appliance. VPN compression is only useful for very slow Internet connections, so we suggest that you disable compression (ip-comp disable). Alternatively, you can upgrade to interim build 8.0(4.16) or later. (CSCsu26649)

Limitations and Restrictions

Please note the following operational limitations.

•Stateful Failover with Phone Proxy—When using Stateful Failover with phone proxy, information is not passed to the standby unit; when the active unit goes down, the call fails, media stops flowing, and the call must be re-established.

•No .NET over Clientless sessions—Clientless sessions do not support .NET framework applications (CSCsv29942).

•When using Clientless SSL VPN Post-SSO parameters for the Citrix Web interface bookmark, Single-Signon (SSO) works but the Citrix portal is missing the Reconnect and Disconnect buttons. Only the Log Off button shows up. When not using SSO over Clientless, all three buttons show up correctly.

Workaround: Use the Cisco HTTP-POST plugin to provide single signon and correct Citrix portal behavior.

•The adaptive security appliance does not support phone proxy and CIPC for remote access.

System Requirements

The sections that follow list the system requirements for operating an adaptive security appliance. This section includes the following topics:

•Memory Requirements

•Operating System and Browser Requirements

•Determining the Software Version

•Upgrading to a New Software Version

Memory Requirements

Table 1 lists the DRAM memory requirements for the adaptive security appliance. The memory listed in this table is the default value that ships with each adaptive security appliance.

Table 1 DRAM Memory Requirements 

ASA Model	Default DRAM Memory (MB)
5505	256
5510	256
5520	512
5540	1024
5550	4096

All adaptive security appliances require a minimum of 64 MB of internal CompactFlash, and they all ship with a minimum of 128 MB of internal CompactFlash.

If your adaptive security appliance has only 64 MB of internal CompactFlash, you should not store multiple system images, or multiple images of the new AnyConnect VPN client components, client/server plugins, or Cisco Secure Desktop.

We recommend that you purchase a 256 MB or 512 MB CompactFlash upgrade from Cisco, choosing from the following part numbers:

•ASA5500-CF-256 MB = ASA 5500 Series CompactFlash, 256 MB

•ASA5500-CF-512 MB = ASA 5500 Series CompactFlash, 512 MB

You can check the size of internal flash and the amount of free flash memory on the adaptive security appliance by doing the following:

•ASDM—Click Tools > File Management. The amounts of total and available flash memory appear on the bottom left in the pane.

•CLI—In Privileged EXEC mode, enter the dir command. The amounts of total and available flash memory appear on the bottom of the output.

For example:

hostname # dir

New Features

Released: August 11, 2008

Table 2 lists the new features forASA or PIX Version 8.0(4).

Table 2 New Features for ASA and PIX Version 8.0(4) 

Feature	Description
Unified Communications Features1
Phone Proxy	Phone Proxy functionality is supported. ASA Phone Proxy provides similar features to those of the Metreos Cisco Unified Phone Proxy with additional support for SIP inspection and enhanced security. The ASA Phone Proxy has the following key features: •Secures remote IP phones by forcing the phones to encrypt signaling and media •Performs certificate-based authentication with remote IP phones •Terminates TLS signaling from IP phones and initiates TCP and TLS to Cisco Unified Mobility Advantage servers •Terminates SRTP and initiates RTP/SRTP to the called party
Mobility Proxy	Secure connectivity (mobility proxy) between Cisco Unified Mobility Advantage clients and servers is supported. Cisco Unified Mobility Advantage solutions include the Cisco Unified Mobile Communicator, an easy-to-use software application for mobile handsets that extends enterprise communications applications and services to mobile phones and smart phones and the Cisco Unified Mobility Advantage server. The mobility solution streamlines the communication experience, enabling real-time collaboration across the enterprise. The ASA in this solution delivers inspection for the MMP (formerly called OLWP) protocol, the proprietary protocol between Cisco Unified Mobile Communicator and Cisco Unified Mobility Advantage. The ASA also acts as a TLS proxy, terminating and reoriginating the TLS signaling between the Cisco Unified Mobile Communicator and Cisco Unified Mobility Advantage.
Presence Federation Proxy	Secure connectivity (presence federation proxy) between Cisco Unified Presence servers and Cisco/Microsoft Presence servers is supported. With the Presence solution, businesses can securely connect their Cisco Unified Presence clients back to their enterprise networks, or share Presence information between Presence servers in different enterprises. The ASA delivers functionality to enable Presence for Internet and intra-enterprise communications. An SSL-enabled Cisco Unified Presence client can establish an SSL connection to the Presence Server. The ASA enables SSL connectivity between server to server communication including third-party Presence servers communicating with Cisco Unified Presence servers. Enterprises share Presence information, and can use IM applications. The ASA inspects SIP messages between the servers.
Remote Access Features
Auto Sign-On with Smart Tunnels for IE1	This feature lets you enable the replacement of logon credentials for WININET connections. Most Microsoft applications use WININET, including Internet Explorer. Mozilla Firefox does not, so it is not supported by this feature. It also supports HTTP-based authentication, therefore form-based authentication does not work with this feature. Credentials are statically associated to destination hosts, not services, so if initial credentials are wrong, they cannot be dynamically corrected during runtime. Also, because of the association with destinations hosts, providing support for an auto sign-on enabled host may not be desirable if you want to deny access to some of the services on that host. To configure a group auto sign-on for smart tunnels, you create a global list of auto sign-on sites, then assign the list to group policies or user names. This feature is not supported with Dynamic Access Policy.
Entrust Certificate Provisioning1	ASDM includes a link to the Entrust website to apply for temporary (test) or discounted permanent SSL identity certificates for your ASA.
Extended Time for User Reauthentication on IKE Rekey	You can configure the security appliance to give remote users more time to enter their credentials on a Phase 1 SA rekey. Previously, when reauthenticate-on-rekey was configured for IKE tunnels and a phase 1 rekey occurred, the security appliance prompted the user to authenticate and only gave the user approximately 2 minutes to enter their credentials. If the user did not enter their credentials in that 2 minute window, the tunnel would be terminated. With this new feature enabled, users now have more time to enter credentials before the tunnel drops. The total amount of time is the difference between the new Phase 1 SA being established, when the rekey actually takes place, and the old Phase 1 SA expiring. With default Phase 1 rekey times set, the difference is roughly 3 hours, or about 15% of the rekey interval.
Persistent IPsec Tunneled Flows	With the persistent IPsec tunneled flows feature enabled, the security appliance preserves and resumes stateful (TCP) tunneled flows after the tunnel drops, then recovers. All other flows are dropped when the tunnel drops and must reestablish when a new tunnel comes up. Preserving the TCP flows allows some older or sensitive applications to keep working through a short-lived tunnel drop. This feature supports IPsec LAN-to-LAN tunnels and Network Extension Mode tunnels from a Hardware Client. It does not support IPsec or AnyConnect/SSL VPN remote access tunnels. See the [no] sysopt connection preserve-vpn-flows command. This option is disabled by default.
Show Active Directory Groups	The CLI command show ad-groups was added to list the active directory groups. ASDM Dynamic Access Policy uses this command to present the administrator with a list of MS AD groups that can be used to define the VPN policy.
Smart Tunnel over Mac OS1	Smart tunnels now support Mac OS.
Local Address Pool Edit	Address pools can be edited without affecting the desired connection. If an address in use is not being eliminated from the pool, the connection is not affected. However, if the address in use is being eliminated from the pool, the connection is brought down. Also available in Version 7.0(8) and 7.2(4).
Firewall Features
QoS Traffic Shaping	If you have a device that transmits packets at a high speed, such as the adaptive 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. See the shape command. See also the crypto ipsec security-association replay command, which lets you configure the IPSec anti-replay window size. One side-effect of priority queueing is packet re-ordering. For IPSec packets, out-of-order packets that are not within the anti-replay window generate warning syslog messages. These warnings become false alarms in the case of priority queueing. This new command avoids possible false alarms. Also available in Version 7.2(4).
TCP Normalization Enhancements	You can now configure TCP normalization actions for certain packet types. Previously, the default actions for these kinds of packets was to drop the packet. Now you can set the TCP normalizer to allow the packets. •TCP invalid ACK check (the invalid-ack command) •TCP packet sequence past window check (the seq-past-window command) •TCP SYN-ACK with data check (the synack-data command) You can also set the TCP out-of-order packet buffer timeout (the queue command timeout keyword). Previously, the timeout was 4 seconds. You can now set the timeout to another value. The default action for packets that exceed MSS has changed from drop to allow (the exceed-mss command). The following non-configurable actions have changed from drop to clear for these packet types: •Bad option length in TCP •TCP Window scale on non-SYN •Bad TCP window scale value •Bad TCP SACK ALLOW option Also available in Version 7.2(4).
TCP Intercept statistics	You can enable collection for TCP Intercept statistics using the threat-detection statistics tcp-intercept command, and view them using the show threat-detection statistics command.
Threat detection shun timeout	You can now configure the shun timeout for threat detection using the threat-detection scanning-threat shun duration command.
Timeout for SIP Provisional Media	You can now configure the timeout for SIP provisional media using the timeout sip-provisional-media command. Also available in Version 7.2(4).
clear conn Command	The clear conn command was added to remove connections. Also available in Version 7.0(8) and 7.2(4).
Fragment full reassembly	The fragment command was enhanced with the reassembly full keywords to enable full reassembly for fragments that are routed through the device. Fragments that terminate at the device are always fully reassembled. Also available in Version 7.0(8) and 7.2(4).
Ethertype ACL MAC Enhancement	EtherType ACLs have been enhanced to allow non-standard MACs. Existing default rules are retained, but no new ones need to be added. Also available in Version 7.0(8) and 7.2(4).
Troubleshooting and Monitoring Features
capture command Enhancement	The capture type asp-drop drop_code command now accepts all as the drop_code, so you can now capture all packets that the adaptive security appliance drops, including those dropped due to security checks. Also available in Version 7.0(8) and 7.2(4).
show asp drop Command Enhancement	Output now includes a timestamp indicating when the counters were last cleared (see the clear asp drop command). It also displays the drop reason keywords next to the description, so you can easily use the capture asp-drop command using the keyword. Also available in Version 7.0(8) and 8.0(4).
clear asp table Command	Added the clear asp table command to clear the hits output by the show asp table commands. Also available in Version 7.0(8) and 7.2(4).
show asp table classify hits Command Enhancement	The hits option was added to the show asp table classify command, showing the timestamp indicating the last time the asp table counters were cleared. It also shows rules with hits values not equal to zero. This permits users to quickly see what rules are being hit, especially since a simple configuration may end up with hundreds of entries in the show asp table classify command. Also available in Version 7.0(8) and 8.0(4).
MIB Enhancement	The CISCO-REMOTE-ACCESS-MONITOR-MIB is implemented more completely. Also available in 8.0(4).
show perfmon Command	Added the following rate outputs: TCP Intercept Connections Established, TCP Intercept Attempts, TCP Embryonic Connections Timeout, and Valid Connections Rate in TCP Intercept. Also available in Version 7.0(8) and 7.2(4).
memory tracking Commands	The following new commands are introduced in this release: •memory tracking enable-This command enables the tracking of heap memory requests. •no memory tracking enable-This command disables tracking of heap memory requests, cleans up all currently gathered information, and returns all heap memory used by the tool itself to the system. •clear memory tracking-This command clears out all currently gathered information but continues to track further memory requests. •show memory tracking-This command shows currently allocated memory tracked by the tool, broken down by the topmost caller function address. •show memory tracking address-This command shows currently allocated memory broken down by each individual piece of memory. The output lists the size, location, and topmost caller function of each currently allocated piece memory tracked by the tool. •show memory tracking dump-This command shows the size, location, partial callstack, and a memory dump of the given memory address. •show memory tracking detail-This command shows various internal details to be used in gaining insight into the internal behavior of the tool. Also available in Version 7.0(8) and 7.2(4).
Routing Features
IPv6 Multicast Listener Discovery Protocol v2 Support	The adaptive security appliance now supports the Multicast Listener Discovery Protocol (MLD) Version 2, to discover the presence of multicast address listeners on their directly attached links, and to discover specifically which multicast addresses are of interest to those neighboring nodes. The adaptive security appliance becomes a multicast address listener, or a host, but not a a multicast router, and responds to Multicast Listener Queries and sends Multicast Listener Reports only. The following commands support this feature: •clear ipv6 mld traffic The clear ipv6 mld traffic command allows you to reset all the Multicast Listener Discovery traffic counters. •show ipv6 mld traffic The show ipv6 mld command allows you to display all the Multicast Listener Discovery traffic counters. •debug ipv6 mld The enhancement to the debug ipv6 command allows the user to display the debug messages for MLD, to see whether the MLD protocol activities are working properly. •show debug ipv6 mld The enhancement to the show debug ipv6 command allows the user to display whether debug ipv6 mld is enabled or disabled. Also available in Version 7.2(4).
Platform Features
Native VLAN support for the ASA 5505	You can now include the native VLAN in an ASA 5505 trunk port using the switchport trunk native vlan command. Also available in Version 7.2(4).
SNMP support for unnamed interfaces	Previously, SNMP only provided information about interfaces that were configured using the nameif command. For example, SNMP only sent traps and performed walks on the IF MIB and IP MIB for interfaces that were named. Because the ASA 5505 has both unnamed switch ports and named VLAN interfaces, SNMP was enhanced to show information about all physical interfaces and logical interfaces; a nameif command is no longer required to display the interfaces using SNMP. These changes affect all models, and not just the ASA 5505.
Failover Features
failover timeout Command	The failover timeout command no longer requires a failover license for use with the static nailed feature. Also available in Version 7.0(8) and 7.2(4).

1 This feature is not supported on the PIX security appliance.

SNMP Changes

This section describes the updated approach used by SNMP to display adaptive security appliance interfaces, and the additional link state traps that are sent for interfaces.

Before Version 8.0(4)/8.1(2), SNMP only provided information about interfaces that were configured using the nameif command. For example, SNMP only sent traps and performed walks on the IF MIB and IP MIB for interfaces that were named. Because the ASA 5505 has both unnamed switch ports and named VLAN interfaces, SNMP was enhanced to show information about all physical interfaces and logical interfaces; a nameif command is no longer required to display the interfaces using SNMP. These changes affect all models, and not just the ASA 5505.

This section includes the following topics:

•IF MIB Output Changes

•IP MIB Output Changes

•SNMP Link State Trap Changes

IF MIB Output Changes

SNMP was enhanced to show information about all physical interfaces and logical interfaces, including internal interfaces; a nameif command is no longer required to display the interfaces using SNMP.

For example, the ifPhysAddr output now includes the MAC addresses of switch ports on the ASA 5505; before, only named VLAN interfaces were shown with a MAC address of 0:0:0:0:0:0.

You might see information about the following internal interfaces:

•Null0—Not currently in use.

•Internal-Data or Internal-Control—Internal interfaces for communicating with SSMs or SSCs.

•_internal_loopback—The loopback interface.

•Virtual—Used for phone proxy media termination functions.

The following topics show a sample interface configuration on the ASA 5505, and sample ifDescr output:

Sample ifDescr Output

The following ifDescr output shows the difference before and after the SNMP changes (changes are shown in bold):

Before:

IF-MIB::ifDescr.1 = Adaptive Security Appliance 'user' interface

IF-MIB::ifDescr.2 = Adaptive Security Appliance 'inside' interface

IF-MIB::ifDescr.3 = Adaptive Security Appliance 'mgmt' interface

IF-MIB::ifDescr.4 = Adaptive Security Appliance 'outside' interface

After:

IF-MIB::ifDescr.1 = Adaptive Security Appliance 'Null0' interface

IF-MIB::ifDescr.2 = Adaptive Security Appliance 'Internal-Data0/0'interface

IF-MIB::ifDescr.3 = Adaptive Security Appliance 'Ethernet0/0' interface

IF-MIB::ifDescr.4 = Adaptive Security Appliance 'Ethernet0/1' interface

IF-MIB::ifDescr.5 = Adaptive Security Appliance 'Ethernet0/2' interface

IF-MIB::ifDescr.6 = Adaptive Security Appliance 'Ethernet0/3' interface

IF-MIB::ifDescr.7 = Adaptive Security Appliance 'Ethernet0/4' interface

IF-MIB::ifDescr.8 = Adaptive Security Appliance 'Ethernet0/5' interface

IF-MIB::ifDescr.9 = Adaptive Security Appliance 'Ethernet0/6' interface

IF-MIB::ifDescr.10 = Adaptive Security Appliance 'Ethernet0/7' interface

IF-MIB::ifDescr.11 = Adaptive Security Appliance 'Internal-Data0/1' interface

IF-MIB::ifDescr.12 = Adaptive Security Appliance '_internal_loopback' interface

IF-MIB::ifDescr.13 = Adaptive Security Appliance 'Virtual254' interface

IF-MIB::ifDescr.14 = Adaptive Security Appliance 'user' interface

IF-MIB::ifDescr.15 = Adaptive Security Appliance 'Vlan40' interface

IF-MIB::ifDescr.16 = Adaptive Security Appliance 'Vlan41' interface

IF-MIB::ifDescr.17 = Adaptive Security Appliance 'Vlan46' interface

IF-MIB::ifDescr.18 = Adaptive Security Appliance 'Vlan47' interface

IF-MIB::ifDescr.19 = Adaptive Security Appliance 'inside' interface

IF-MIB::ifDescr.20 = Adaptive Security Appliance 'Vlan112' interface

IF-MIB::ifDescr.21 = Adaptive Security Appliance 'mgmt' interface

IF-MIB::ifDescr.22 = Adaptive Security Appliance 'outside' interface

IP MIB Output Changes

Walking the IP MIB now shows IP addresses assigned to all interfaces, not just those configured using the nameif command.

SNMP Link State Trap Changes

SNMP now sends traps at bootup, when an interface is shut down, or when an interface is brought up for all physical interfaces and logical interfaces; a nameif command is no longer required to send traps about interfaces. Before this enhancement, traps were sent only for interfaces that had a name configured.
