Cisco PIX Security Appliance Release Notes Version 7.2
OL-10104-01
New Features
Resource Management for Security Contexts
If you find that one or more contexts use too many resources, and they cause other contexts to be denied
connections, for example, then you can configure resource management to limit the use of resources per
context.
For more information, see the “Configuring Resource Management”
section in the Cisco Security
Appliance Command Line Configuration Guide.
Authentication for Through Traffic and Management Access Supports All Servers Previously
Supported for VPN Clients
All server types can be used for firewall authentication with the following exceptions: HTTP Form
protocol supports single sign-on authentication for WebVPN users only and SDI is not supported for
HTTP administrative access.
For more information, see the “Summary of Support”
section in the Cisco Security Appliance Command
Line Configuration Guide.
Auto Update
The security appliance can now be configured as an Auto Update server in addition to being configured as an
Auto Update client. The existing client-update command (which is also used to update VPN clients) is
enhanced to support the new Auto Update server functionality, and includes new keywords and arguments
that the security appliance needs to update security appliances configured as clients. For the security
appliance configured as an Auto Update client, the auto-update command continues to be the command used
to configure the parameters that the security appliance needs to communicate with the Auto Update server.
For more information, see the “Configuring Auto Update Support” section in the Cisco Security
Appliance Command Line Configuration Guide. For a complete description of the command syntax, see
the Cisco Security Appliance Command Reference.
Dead Connection Detection (DCD)
This feature allows the security appliance to automatically detect and expire dead connections. In
previous versions, dead connections never timed out; they were given an infinite timeout. Manual
intervention was required to ensure that the number of dead connections did not overwhelm the security
appliance. With this feature, dead connections are detected and expired automatically, without
interfering with connections that can still handle traffic. The set connection timeout and show
service-policy commands provide DCD support.
For more information, see the “Configuring Connection Limits and Timeouts” section in the Cisco
Security Appliance Command Line Configuration Guide. For a complete description of the command
syntax, see the Cisco Security Appliance Command Reference.
Configurable Prompt
With this feature, the user can see the failover status of the security appliance without having to enter
the show failover command and parse the output. This feature allows users to see the chassis slot number
of the failover unit. Previously, the prompt reflected just the hostname, security context, and
configuration mode. The prompt command provides support for this feature.
