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 6-2).

Table 6-2	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/RSP0/CPU0:router# show	configuration sessions
Session	Line	User	Date		Lock
00000211-002c409b-00000000	con0_RSP1_CPU0		UNKNOWN	Mon Feb	2 01:02:09 2004

RP/0/RSP0/CPU0:router# clear configuration sessions 00000211-002c409b-00000000

session ID '00000211-002cb09b-00000000' terminated

Contacting TAC for Additional Assistance

If you remove configurations and the low-memory condition remains, you may need to contact TAC for additional assistance. See the “Additional Sources for Information” section on page 6-1.

Interfaces Not Coming Up

The router interfaces are directly used in processing network traffic, so their status information is crucial to understanding how the device is functioning. This section contains information on the EXEC mode commands used to verify that the router interfaces are operational. The basic commands used in this process are summarized in Table 6-3.

Table 6-3 show interface Commands

Command	Description
show interfaces	Displays detailed information about all interfaces installed or
	configured on the device, whether or not they are operational.
show interfaces type instance	Specifies a particular interface, rather than displaying information for
	all interfaces, as in the following example:
	show interface gi0/1/0/0
show ipv4 interface	Displays basic, IP-related information for all available interfaces.
show ipv4 interface brief	Quickly displays the most critical information about the interfaces,
	including the interface status (up or down) and the protocol status.
