Chapter 11 Miscellaneous SSG Features

SSG Unconfig

Configuration of Packet Filtering

To configure SSG ACLs, use the following Cisco-AV pair attributes:

Downstream Access Control List (outacl)

Cisco-AVpair = "ip:outacl[#number]={standard-access-control-list

extended-access-control-list}"

Upstream Access Control List (inacl)

Cisco-AVpair = "ip:inacl[#number]={standard-access-control-list extended-access-control-list}"

For more information, refer to the Service Selection Gateway, Release 12.2(15)B feature module.

Configuration Example for Packet Filtering

The following is an example of a downstream ACL (outacl):

Cisco-AVpair = "ip:outacl#101=deny tcp 192.168.1.0 0.0.0.255 any eq 21"

The following is an example of an upstream ACL (inacl):

Cisco-AVpair = "ip:inacl#101=deny tcp 192.168.1.0 0.0.0.255 any eq 21"

SSG Unconfig

The SSG Unconfig feature enhances your ability to disable SSG at any time and releases the data structures and system resources created by SSG when SSG is unconfigured.

SSG Unconfig removes SSG allocated resources when you globally disable SSG after it was enabled. When you enable SSG, the SSG subsystem in the Cisco IOS software acquires system resources that are never released, even after you disable SSG. The SSG Unconfig feature enables you to release and clean up system resources when SSG is not in use by entering the no ssg enable force-cleanupcommand.

The SSG Unconfig feature also enhances several IOS commands to allow you to delete all host objects, a range of host objects, or all service objects (connection objects). Enhancements to the show ssg host command allow you to display information about an interface and its IP address when you enable host-key mode on that interface. For more information about the SSG commands, refer to the

Cisco 10000 Series Routers Command Quick Reference Guide.

For more information about the SSG Unconfig feature, refer to the SSG Unconfig, Release 12.2(15)B feature module and the Service Selection Gateway, Release 12.2(15)B feature module.

Restrictions for SSG Unconfig

SSG Unconfig clears all SSG resources on the system. Therefore, if you no longer need to run SSG features on the router, instead of using SSG Unconfig enter the no ssg enable force-cleanupcommand after all users are logged out.
