If display item "Discard" is larger than 0 when this command is executed, a failure discarding packets has occurred. Use the show interfaces command to retrieve detail information of the port.

3.4.2Communication Failure in Basic Switching Unit BSU/PSP

If BSU/PSP has possibly caused the communication failure, check for the BSU/PSP status as follows.

(1) Checking BSU/PSP operation status

1.Checking log

For the log, see the manual "Message Log Reference."

2.Isolating the problem according to the BSU/PSP operation status

Check the BSU/PSP operation status by using the show system command, and isolate the problem according to the table below.
