Rolling Back to a Previously Committed Configuration

You can roll back the system to a previous committed configuration, as described in the “Managing Configuration History and Rollback” section on page 5-3.

Clearing Configuration Sessions

Active configuration sessions and their associated target configurations can consume system memory. Users with the appropriate access privileges can display the open configuration sessions of other users and terminate those sessions, if necessary (see Table 7-3).

Table 7-3	Session Commands
Command		Description
show configuration sessions		Displays the active configuration sessions.
clear configuration sessions session-id		Clears a configuration session.

In the following example, the open configuration sessions are displayed with the show configuration sessions command. The clear configuration sessions command is then used to clear a configuration session.

RP/0/RP0/CPU0:router# show configuration sessions

Session	Line	User	Date	Lock
00000211-002c409b-00000000	con0_RP1_CPU0 UNKNOWN		Mon Feb	2 01:02:09 2004
