
If the ports displayed in the command output are different from the ports used for stack
connection, reconnect ports.

If the ports displayed in the command output are the same as the ports used for stack
connection, go to step 7.
Step 7 Check that the stack cards and stack cables are functioning properly.

Check the status of physical member interfaces in the display stack port command
output. If all the member ports are Up, go to step 8.

If a member port is Down, check whether the switch connected to the port has been
powered off or is restarting. If so, check the port status after the remote switch restarts. If
not, replace the stack card on the local switch or the stack cable on this port.
If the fault persists, go to step 8.
Step 8 Collect the following information and contact Huawei technical support personnel.

Physical ports of the same logical port are connected differently:

5.2 A Stack Cannot Run Properly Because One Member
Switch Becomes Faulty
When faults often occur on a member switch of a stack, the stack cannot run properly. To
ensure the reliability of other running member switches, you need to isolate the member
switch from the stack. This isolation mode applies only to service port connection but not to
stack card connection because the number of stack port limitations of stack cards.
