Cisco ASA 5500 Series Release Notes Version 7.1(2)
March 2006, OL-10087-01Contents
This document includes the following sections:
Introduction
The Cisco ASA 5500 series security appliance are purpose-built solutions that combine best-of-breed 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. This version introduces significant enhancements to major functional areas including: new Anti-X Services, VPN services, and management/monitoring.
Additionally, the adaptive security appliance software supports Adaptive Security Device Manager. 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 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.

256 MB
ASA 5520
512 MB
ASA 5540
1 GB
All adaptive security appliances require a minimum of 64 MB of internal CompactFlash.
Determining the Software Version
Use the show version command to verify the software version of your adaptive security appliance.
Upgrading to a New Software Version
If you have a Cisco.com (CDC) login, you can obtain software from the following website:
http://www.cisco.com/public/sw-center/
You must upgrade from Version 7.0(x) or 7.1(1) to 7.1(2) because older versions of the ASA images do not recognize new ASDM images and new ASA images do not recognize old ASDM images. Similarly, if you downgrade to an earlier version of ASA software, you must also downgrade the ASDM image.
You can also use command-line interface to download the image. See the "Downloading Software or Configuration Files to Flash Memory" section in the Cisco Security Appliance Command Line Configuration Guide.
To upgrade from Version 7.0.(x) or 7.1(1) to 7.1(2), you must perform the following steps:

Features
ASA Version 7.1(2) is a sustaining release that fixes product deficiencies. It includes no new features. For information about features new for ASA Release 7.1, see the Cisco ASA 5500 Series Release Notes, Version 7.1(1).
Important Notes
This section lists important notes related to Version 7.1(2).
SSL VPN Licenses
Beginning with Version 7.1(1), SSL VPN (WebVPN) services require a license. These services are now licensed on a per-user session basis, with licensing levels at 10, 50, 100, 250, 500, 750, 1000, and 2500 user sessions. The complete SSL VPN feature functionality offered by the adaptive security appliance is included in this single SSL VPN license. No per-feature licenses are required. This SSL VPN license has a one-time fee and lasts for the lifetime of the adaptive security appliance. Upon installation of Version 7.1(1) or later, two simultaneous SSL VPN user sessions are included for evaluation.
ActiveX and WebVPN
Many ActiveX controls are custom and require special treatment by WebVPN. Please contact Cisco TAC if your application uses ActiveX controls and you have problems with its functionality over a WebVPN connection (CSCsb85180).
CIFS Files
If a remote user accesses CIFS files using Internet Explorer, the filename in the File Download window might not display some Japanese Shift_JIS characters correctly. However, the Open and Save functions do work properly. This issue does not occur with Netscape.
Failover and WebVPN and SVC Connections
To ensure that WebVPN and SVC connections reconnect quickly in the event of a failover, enable the adaptive security appliancee to respond to incoming client TCP packets with the service resetoutside command from global configuration mode:
[no] service resetoutsideThis command causes the adaptive security appliance that takes over the existing WebVPN and SVC connections to send TCP RST packets in response to incoming client TCP packets, causing client connections to reestablish quicker. If you do not enable the service resetoutside command, the security appliance drops TCP packets from failed-over connections and waits for each client to reestablish the TCP connection. This may take longer or result in the session being lost due to timeout.
The following example enables the security appliance to send TCP RST packets:
hostname(config)# service resetoutsideFIPS 140-2
The adaptive security appliances are on the FIPS 140-2 Pre-Validation List.
WebVPN ACLS and DNS Hostname
When a deny webtype URL ACL (DNS-based) is defined, but the DNS-based URL is not reachable, the browser displays q "DNS Error" popup. The ACL hit counter does not increment.
If an IP address rather than a DNS name defines a deny webtype URL, then the hit counter does record the traffic flow hitting the ACL, and the browser displays a "Connection Error."
Proxy Server and ASA
If WebVPN is configured to use an HTTP(S)-proxy server to service all requests for browsing HTTP and/or HTTPS sites, the client/browser may expect the following behavior:
1.
2.
Only when the HTTP(S) proxy server notifies the ASA of the inaccessible URL, can the ASA notify the client browser about the error.
Mismatch PFS
The PFS setting on the VPN client and the adaptive security appliance must match.
Readme Document for the Conduits and Outbound List Conversion Tool 1.2
The adaptive security appliance Outbound/Conduit Conversion tool assists in converting configurations with outbound or conduit commands to similar configurations using ACLs. ACL-based configurations provide uniformity and leverage the powerful ACL feature set. ACL based configurations provide the following benefit:
•
VPN Load Balancing Requirements
VPN load balancing for the adaptive security appliance requires an ASA 5520 or ASA 5540. It also requires a 3DES-AES encryption license.

Note
Submitting a Service Request
Using the online TAC Service Request Tool is the fastest way to open S3 and S4 service requests. (S3 and S4 service requests are those in which your network is minimally impaired or for which you require product information.) After you describe your situation, the TAC Service Request Tool provides recommended solutions. If your issue is not resolved using the recommended resources, your service request is assigned to a Cisco engineer. The TAC Service Request Tool is located at this URL:
http://www.cisco.com/techsupport/servicerequest
For S1 or S2 service requests, or if you do not have Internet access, contact the Cisco TAC by telephone. (S1 or S2 service requests are those in which your production network is down or severely degraded.) Cisco engineers are assigned immediately to S1 and S2 service requests to help keep your business operations running smoothly.
To open a service request by telephone, use one of the following numbers:
Asia-Pacific: +61 2 8446 7411 (Australia: 1 800 805 227)
EMEA: +32 2 704 55 55
USA: 1 800 553-2447For a complete list of Cisco TAC contacts, go to this URL:

Definitions of Service Request Severity
To ensure that all service requests are reported in a standard format, Cisco has established severity definitions.
Severity 1 (S1)—An existing network is down, or there is a critical impact to your business operations. You and Cisco will commit all necessary resources around the clock to resolve the situation.
Severity 2 (S2)—Operation of an existing network is severely degraded, or significant aspects of your business operations are negatively affected by inadequate performance of Cisco products. You and Cisco will commit full-time resources during normal business hours to resolve the situation.
Severity 3 (S3)—Operational performance of the network is impaired, while most business operations remain functional. You and Cisco will commit resources during normal business hours to restore service to satisfactory levels.
Severity 4 (S4)—You require information or assistance with Cisco product capabilities, installation, or configuration. There is little or no effect on your business operations.
