show mac <mod/port>
This command displays the MAC counters, and is useful in the determination of whether counters are
incrementing as expected. This command shows the total unicast, multicast, and broadcast frames received on
a port. The In−lost counter on the Catalyst 4000 reflects the sum of all error packets received on the port. This
is different then the behavior of the In−Lost counter on the Catalyst 5000 switches; which reflects the sum of
all receive buffer failures. The out−Lost counter on both the Catalyst 4000 and 5000, reflect outgoing frames
that were lost before forwarded due to insufficient buffer space. This is commonly caused if you
oversubscribe the interface.
See the Seeing errors on the ports section of this document for troubleshooting steps. Refer to the show mac
command for more information.
