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 of Information” section on page 6-119.
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 6-4.
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/0/0/CPU0:router(admin)# show platform

Command Description

configured on the device, whether or not they are operational.

all interfaces, as in the following example:
show interface POS0/1/0/0
show ipv4 interface
show ipv6 interface
Displays basic, IP-related information for all available interfaces.
