Introduction


Note The PIX 501, PIX 506/506E, and PIX 520 security appliances are not supported in software Version 7.2(4).


The Cisco PIX 500 series security appliance delivers unprecedented levels of defense against threats to the network with deeper web inspection and flow-specific analysis, improved secure connectivity through end-point security posture validation and voice and video over VPN support. It also provides enhanced support for intelligent information networks through improved network integration, resiliency, and scalability.

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

Additionally, the 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 security appliance, ASDM accelerates 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 security appliance. Its secure, web-based design enables anytime, anywhere access to security appliances.

System Requirements

The sections that follow list the system requirements for operating a security appliance.


Note The PIX 501, PIX 506/506E, and PIX 520 security appliances are not supported in software Version 7.2(4).


Memory Requirements

If you are using a PIX 515/515E running PIX Version 6.2/6.3, you need to upgrade your memory before performing an upgrade to PIX Version 7.0. PIX Version 7.0 requires at least 64 MB of RAM for Restricted (R) licenses and 128 MB of RAM for Unrestricted (UR) and Failover (FO) licenses. The following security appliance platforms require at least 64 MB of RAM. Table 1 lists flash memory requirements for Version 7.2(4).

For more information on minimum memory requirements, see the "Minimum Memory Requirements" section in the Guide for Cisco PIX 6.2 and 6.3 Users Upgrading to Cisco PIX Software Version 7.0.

Software Requirements

Version 7.2(4) requires the following:

1. The minimum software version required before performing an upgrade to PIX Version 7.2(4) is PIX Version 7.0. If you are running a PIX version prior to PIX Version 6.2, you must first upgrade to PIX Version 6.2 or PIX Version 6.3 before you can begin the upgrade to PIX Version 7.0.

To upgrade your PIX software image, go to the following website: http://www.cisco.com/pcgi-bin/tablebuild.pl/pix

2. For information on specific licenses supported on each model of the security appliance, go to the following website: www.cisco.com/go/license

3. If you are upgrading from a previous PIX version, save your configuration and write down your activation key and serial number. See "Upgrading to a New Software Version" for new installation requirements.

Maximum Recommended Configuration File Size

For the PIX 525 and PIX 535, the maximum supported configuration file size is 2 MB for Version 7.2(4). For the PIX 515/515E, the maximum supported configuration file size is 1 MB for Version 7.2(4). If you are using ASDM, we recommend no more than a 500 KB configuration file because larger configuration files can interfere with the performance of ASDM on your workstation.

While configuration files up to 2 MB are supported on the PIX 525 and PIX 535, be aware that such large configuration files can reduce system performance. For example, a large configuration file is likely to noticeably slow execution times in the following situations:

While executing commands such as the write terminal and show running-config commands

Failover (the configuration synchronization time)

New Features

This section lists the new features for Version 7.2(4). All new features are supported in ASDM 5.2(4).

capture command Enhancement

The capture asp type asp-drop all command captures all packets that the security appliance drops, including those dropped due to security checks.

clear conn Command

The clear conn command was added to remove connections.

IPv6 Multicast Listener Discovery Protocol v2 Support

The PIX 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. PIX 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:

show ipv6 mld Command

debug ipv6 Command Enhancement

show debug ipv6 mld Command Enhancement

clear ipv6 mld traffic Command

The clear ipv6 mld traffic command allows you to reset all the Multicast Listener Discovery traffic counters. the syntax is as follows:

clear ipv6 mld traffic

show ipv6 mld Command

The show ipv6 mld command allows you to display all the Multicast Listener Discovery traffic counters. the syntax is as follows:

show ipv6 mld traffic

debug ipv6 Command Enhancement

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. This enhancement adds the mld option.

debug ipv6 {icmp | interface | mld | nd | packet | routing}

show debug ipv6 mld Command Enhancement

The enhancement to the show debug ipv6 command allows the user to display whether debug ipv6 mld is enabled or disabled.

show debug ipv6 mld

MIB Enhancement

The CISCO-REMOTE-ACCESS-MONITOR-MIB is implemented more completely.

QoS Traffic Shaping

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. See 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.

show asp drop Command Enhancement

The show asp drop command now displays the capture asp-drop type keywords. This enhancement displays the particular capture type as part of the output of the show asp drop command.

A timestamp was also added indicating when the last time the asp drop counters were cleared.

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.

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

TCP Urgent Flag Syslog

When the TCP urgent flag of a TCP packet is cleared and debugging is enabled, a syslog is generated.

Timeout for SIP Provisional Media

You can now configure the timeout for SIP provisional media using the timeout sip-provisional-media command.

Important Notes

This section lists important notes related to Version 7.2(4).

User Upgrade Guide

Before upgrading to Version 7.2(4), read the Guide for Cisco PIX 6.2 and 6.3 Users Upgrading in Cisco PIX Software Version 7.0. This guide includes information about deprecated features and other changes in the Cisco PIX software Version 7.0. For a list of deprecated features and user upgrade information, go to the following URL:

http://www.cisco.com/en/US/docs/security/asa/asa70/pix_upgrade/upgrade/guide/pixupgrd.html


Caution If you share the Stateful Failover update link with a link for regular traffic such as your inside interface, you must change your configuration before upgrading. Do not upgrade until you have corrected your configuration, as this is not a supported configuration and Version 7.2(4) treats the LAN failover and Stateful Failover update interfaces as special interfaces. If you upgrade to Version 7.2(4) with a configuration that shares an interface for both regular traffic and the Stateful Failover updates, configuration related to the regular traffic interface will be lost after the upgrade. The lost configuration may prevent you from connecting to the security appliance over the network.

Readme Document for the Conduits and Outbound List Conversion Tool 1.2

The security appliance Outbound and Conduit Conversion tool assists in converting configurations with outbound or conduit commands to similar configurations using ACLs. ACL-based configurations provide uniformity and optimize the ACL feature set. ACL-based configurations provide the following benefits:

ACE insertion capability—Provides simplified system configuration and management, which allows you to add, delete or modify individual ACEs.

Outbound ACLs and time-based ACLs—Provides administrators with improved flexibility for defining access control policies by adding support for outbound ACLs and time-based ACLs.

Enabling and Disabling of ACL entries—Provides a convenient troubleshooting tool that allows administrators to test and fine-tune ACLs without the need to remove and replace ACL entries.

Features not Supported

The PPTP feature is not supported.

Downgrade to Previous Version

To downgrade to a previous version of the operating system software (software image), use the downgrade command in privileged EXEC mode. Use the downgrade command only if you want to downgrade to a version other than 7.x.

For more information and a complete description of the command syntax, see the Cisco Security Appliance Command Reference.


Caution Do not load a previous version of software if your PIX security appliance is currently running PIX Version 7.0 or later. If you load a software image from monitor mode onto a PIX security appliance that has a PIX Version 7.0 file system, unpredictable behavior may occur and is not supported. We strongly recommend that you use the downgrade command from a running PIX Version 7.0 image that facilitates the downgrade process.

Caveats

The following sections describe the caveats for the Version 7.2(4).

For your convenience in locating caveats in Cisco's Bug Toolkit, the caveat titles listed in this section are drawn directly from the Bug Toolkit database. These caveat titles are not intended to be read as complete sentences because the title field length is limited. In the caveat titles, some truncation of wording or punctuation may be necessary to provide the most complete and concise description. The only modifications made to these titles are as follows:

Commands are in boldface type.

Product names and acronyms may be standardized.

Spelling errors and typos may be corrected.
