Verifying the Interface Is Up
Example:
Router# show interfaces gigabitethernet 2/0/1
Router# show interfaces tengigabitethernet 7/0/0
Router# show interfaces fastethernet 3/0/0
Step 2
Verify that the interface is up.
Example:
Router# show interfaces gigabitethernet 2/0/1
GigabitEthernet2/0/1 is up
, line protocol is up
Router# show interfaces tengigabitethernet 7/0/0
TenGigabitEthernet7/0/0 is up,
line protocol is up (connected)
Router# show interfaces fastethernet 3/0/0
FastEthernet3/0/0 is up,
line protocol is up
Step 3
Verify that the line protocol is up.
Example:
Router# show interfaces gigabitethernet 2/0/1
GigabitEthernet2/0/1 is up, line protocol is up
Router# show interfaces tengigabitethernet 7/0/0
TenGigabitEthernet7/0/0 is up, line protocol is up (connected)
Router# show interfaces fastethernet 3/0/0
FastEthernet3/0/0 is up,
line protocol is up
Step 4
Observe the CRC counter.
Example:
0 input errors, 0 CRC, 0 frame, 130043940 overrun, 0 ignored
Step 5
Observe the carrier signal counters.
Example:
0 lost carrier, 0 no carrier
, 0 pause output
0 output buffer failures, 0 output buffers swapped out

Verifying the Interface Is Up
In the output of the show interfaces gigabitethernet, show interfaces tengigabitethernet, or show interfaces
fastethernet command, verify that the interface is up. If the interface is down, perform the following corrective
actions:
• If the interface is administratively down , use the no shutdown interface configuration command to
