(3) Checking statistics
You can use the
show port statistics command to check the number of sent and received
packets and the number of discarded send and receive packets for all ports on the Switch.

Note that if a value of the display item Discard is larger than 0, it indicates that a failure has
occurred and packets have been discarded. Use the
show interfaces command to obtain the
detailed information about the target port.
3.5.2 BSU/PSP communication failures
If it is possible that BSU/PSP units cause the communication failure, perform the check procedure
described below.
(1) Checking the operating status of BSU/PSP units
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 operating status of BSU/PSP units
Use the
show system command to check the operating status of BSU/PSP units, and isolate
the cause of the problem according to the following table.
Table 3-9: Checking the operating status of a BSU/PSP and action to take
7 disable or
locked
The shutdown configuration
command is set.
Make sure the cable is connected to the target port, and set
the
no shutdown configuration command to activate the
target port.
No. Operating status
of the BSU/PSP
Cause Action
1
active The target BSU/PSP is operating
normally as an active unit.
See 3.5.1 Ethernet port cannot be
connected.
2
standby hot The target BSU/PSP is operating
normally as a standby unit in hot
standby mode.
See 3.5.1 Ethernet port cannot be
connected.
3
standby cold The target BSU is operating normally as
a standby unit in cold standby mode.
See 3.5.1 Ethernet port cannot be
connected.
4
standby cold2 The target BSU/PSP is operating
normally as a standby unit in cold
standby 2 mode.
See 3.5.1 Ethernet port cannot be
connected.
5
fault The configuration contains a setting that
cannot be used.
Correctly set the flow distribution pattern for
the filters and QoS functionality by using the
fldm prefer configuration command.
No. Port status Cause Action
