<Sysname> display interface brief
The brief information of interface(s) under route mode:
Link: ADM - administratively down; Stby - standby
Description
Number of packets dropped because the transmit buffer of the
interface ran low.
Number of packets that failed to be transmitted, for example, because
of Ethernet collisions.
Number of frames that the interface deferred to transmit because of
detected collisions.
Number of frames that the interface stopped transmitting because
Ethernet collisions were detected during transmission.
Number of frames that the interface 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.
Description
The interface is physically up.
The interface is physically down, because no physical connection exists.
Possible reason: The network cable is disconnected or faulty.
The interface is physically down, because it was shut 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 OAM connection is disconnected.
The interface is physically down, because a DLDP connection fails to be
established on it or the 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.
