Description
Use the qe monitor errpkt command to configure error packets detection function on
current interface.
A switch does not detect error packets on current interface by default.
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.
Example
# Specify to detect error packets that are of runt type on Ethernet4/0/1 interface.

protection measures to ensure that its interfaces send/receive packets properly.
