Interfaces Not Coming Up
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 
). 
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

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 6-2
Session Commands
Command
Description
show configuration sessions

clear configuration sessions session-id
Clears a configuration session.
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.
