Upon enabling queue traffic monitoring on a switch, the switch monitors the
queue traffic and relieves blocks in the output queue of its interfaces.
The criterion used to distinguish a block is that the queue is full, and the traffic of
the corresponding interface is less than the specified threshold.
The following describes configuration tasks of queue traffic monitoring.

If the switch receives a great number of error packets, it will not be able to
send/receive packets properly. With error packets monitoring enabled, the switch
collects information about received error packets regularly. If error packets are
detected, it takes protection measures to ensure that its interfaces send/receive
packets properly.
The following describes configuration tasks of error packets monitoring.
