Number of frames that the port deferred to transmit because of
detected collisions.
Number of frames that the port stopped transmitting because Ethernet
collisions were detected during transmission.
Number of frames that the port deferred to transmit after transmitting
their first 512 bits, because of detected collisions.
Number of carrier losses during transmission. This counter applies to
serial WAN interfaces.
Number of times that the port failed to detect the carrier when
attempting to send frames. This counter applies to serial WAN
interfaces.
The interface is physically up.
The interface is physically down because no physical connection exists
(possibly reason: the network cable is disconnected or faulty).
The interface is physically down because it was brought down with the
shutdown command. To restore its physical state, use the undo shutdown
command.
The interface is physically down because the aggregate interface
corresponding to the aggregation group to which it belongs was shut down
with the shutdown command.
The interface is physically down because an OAM connection fails to be
established on it or the current OAM connection is disconnected.
The interface is physically down because a DLDP connection fails to be
established on it or the current DLDP connection is disconnected.
The interface is shut down because a loop is detected on it.
The interface is shut down by the BPDU guard function.
The interface is physically down because the uplink of the monitor link group
to which it belongs is down.
