3.5 Network interface communication failures
3.5.1 Ethernet port cannot be connected
If it is possible that the Ethernet port caused the communication failure, do the following:
• For AX6700S, AX6600S, or AX6300S series switches:
Check the NIF status, port status, and port statistics in this order.
• For AX3800S, AX3600S, or AX2400S series switches:
Check the port status and port statistics in this order.
(1) Checking the status of the NIF
1. Checking the log
For details about the log, see the manual Message and Log Reference.
2. Isolating the cause of the problem by checking the NIF status
Use the
show interfaces command to check the NIF status, and isolate the cause of the
problem according to the following table.
Table 3-7: Checking the NIF status and action to take
(2) Checking the port status
1. Checking the log
No. NIF status Cause Action
1
active The target NIF is operating
normally.
Check the port status according to Table 3-8: Checking the
port status and action to take.
2
notconnect The target NIF is not
implemented.
Implement the NIF board.
3
inactive The inactivate command is
set.
Use the activate command to activate the target NIF.
The target NIF is not fully
inserted.
Implement the NIF board correctly.
The NIF is not operating. Use the show system command to check the operating
status of the BSU, and activate the NIF.
Use the
show system command to check the operating
status of the PSP, and activate the NIF.
A NIF not supported in this
software version is implemented.
Check the NIF board type and the software version, and then
either replace the NIF board or update the software.
A NIF not supported in the
Switch is implemented.
Replace the NIF board.
4
fault A failure has occurred on the
target NIF.
Based on the log entry for the target NIF displayed by the
show logging command, see the manual Message and Log
Reference and take the action described in Action.
5
initialize The target NIF is being
initialized.
Wait until the initialization is complete.
6
disable no power enable is set by a
configuration command.
Make sure that the NIF board to use is implemented, and use
the power enable configuration command to put the target
NIF into active status.
