5 Diagnosing and Rectifying Faults

1. On the interface view, run the following
commands to check whether the fault is
rectified:
[~HUAWEI]interface 10ge 1/17/1

● If yes, no further action is required.
● If no, go to 2.
2. Run the reboot command to restart the
switch module.
Run the display interface command and
check CRC and Symbols.
1. If the values of CRC and Symbols are not
zero, perform the following operations:
● Ensure that the optical cables are
connected properly to the faulty switch
module and the device it is directly
connected to.
● Check whether any optical cables are
damaged.
● Check whether the optical modules of
the faulty switch module and the device
it is directly connected to are working
properly.
● If there is a transmission device between
the switch module and its connected
device, check the transmission device
gateway for alarms.
2. If the values of CRC and Symbols are zero,
run the reboot command to restart the
switch module.
