Cisco PIX Security Appliance Release Notes Version 7.2

OL-10104-01

New Features

Multicast Routing Enhancements

Multicast routing enhancements allows you to define multicast boundaries so that domains with RPs that

have the same IP address do not leak into each other, to filter PIM neighbors to better control the PIM

process, and to filter PIM bidir neighbors to support mixed bidirectional and sparse-mode networks.

For more information, see the “Configuring Multicast Routing” chapter in the Cisco Security Appliance

Command Line Configuration Guide.

Private and Automatic MAC Address Assignments and Generation for Multiple Context Mode

You can assign a private MAC address (both active and standby for failover) for each interface. For

multiple context mode, you can automatically generate unique MAC addresses for shared context

interfaces, which makes classifying packets into contexts more reliable.

The new mac-address auto command allows you to automatically assign private MAC addresses to each

shared context interface.

For more information, see the “Automatically Assigning MAC Addresses to Context Interfaces”

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.

Expanded DNS Domain Name Usage

You can use DNS domain names, such as www.example.com, when configuring AAA servers and also

with the ping, traceroute, and copy commands.

For a complete description of the command syntax, see the Cisco Security Appliance Command

Reference.

Resiliency and Scalability

This section includes the following topics:

• Sub-second Failover, page 13

• Standby ISP Support, page 13

Sub-second Failover

This feature allows you to configure failover to detect and respond to failures in under a second.

For more information, see the “Configuring Failover” chapter in the Cisco Security Appliance Command

Line Configuration Guide.

Standby ISP Support

This feature allows you to configure a link standby ISP if the link to your primary ISP fails. It uses static

routing and object tracking to determine the availability of the primary route and to activate the

secondary route when the primary route fails.

For more information, see the “Configuring IP Routing and DHCP Services” chapter in the Cisco Security

Appliance Command Line Configuration Guide.
