Interfaces Not Coming Up

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 7-1.

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 7-4.

Table 7-4 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 POS0/1/0/0
show ipv4 interface	Displays basic, IP-related information for all available interfaces.
show ipv6 interface
show ipv4 interface brief	Quickly displays the most critical information about the interfaces,
show ipv6 interface brief	including the interface status (up or down) and the protocol status.

Verifying the System Interfaces

Perform the following steps to verify the system interfaces.

Step 1 Enter the show platform command in administration EXEC to verify that all nodes are in the “IOS XR RUN” state:

RP/0/RP0/CPU0:router(admin)# show platform
