Configure a PIX Security Appliance to Perform in Multiple Context Mode
Manage security contexts

A context can only be removed by editing the system configuration. To remove a context, use the no form of the context command . The current admin context, cannot be removed unless all other contexts are removed. To clear all context configurations in the system configuration, use the clear configure context command in global configuration mode. Context can be created or removed without a reboot.

NOTE:

If failover is used, there is a delay between when the context is removed on the active unit and when the context is removed on the standby unit. An error message indicating that the number of interfaces on the active and standby units are not consistent may be displayed. This error is temporary and can be ignored.

Use the admin-context command in global configuration mode to set the admin context for the system configuration . Any context can be set to be the admin context, as long as the context configuration resides on the Flash memory DIMM.

When logged into the system execution space or the admin context, administrators can change between contexts and perform configuration and monitoring tasks within each context. Use the changeto command in privileged EXEC mode to change between security contexts and the system context .

Use the show context command to view all contexts . From the system execution space, a list of contexts can be viewed including the name, interfaces, and configuration file. In the system execution space, the PIX Security Appliance displays all contexts if no name is specified.

The show context detail command reveals additional details about the context(s), including the running state and information for internal use .

The show context count command lists the number of contexts configured.
