Interface failure

Symptom
The LED for the interface is off.
NOTE:
A management Ethernet port has two LEDs, LINK and ACT. When the LINK LED is off, the
management Ethernet port fails.
Solution
To resolve the problem:
Make sure the MPU or LPU where the interface resides operates correctly. For more

b. Replace the transceiver module.
Verify that the speed and duplex settings of the interfaces on the two ends are the same.

NOTE:
• If an interface is brought down by the shutdown command, use the undo shutdown
command to bring up the interface.
• After an interface fails, if the switch has an idle interface of the same type, you can connect
the cable to the idle interface.
