show port
UnderSize Number of received frames less than 64 octets long (but are otherwise
well-formed).
Single-Coll Number of times one collision occurred before the port transmitted a frame
to the media successfully.
Multi-Coll Number of times multiple collisions occurred before the port transmitted a
frame to the media successfully.
Late-Coll Number of late collisions (collisions outside the collision domain).
Excess-Col Number of excessive collisions that occurred on the port (indicating that a
frame encountered 16 collisions and was discarded).
Carri-Sen Number of times the port sensed a carrier (to determine whether the cable is
currently being used).
Runts Number of received runt frames (frames that are smaller than the minimum
IEEE 802.3 frame size) on the port.
Giants Number of received giant frames (frames that exceed the maximum IEEE
802.3 frame size) on the port.
CE-State Connection entity status.
Conn-State Connection state of the port, as follows:
• Disabled—The port has no line module or was disabled by the user.
• Connecting—The port attempted to connect or was disabled.
• Standby—The connection was withheld or was the inactive port of a
dual-homing concentrator.
• Active—The port made a connection.
• Other—The concentrator was unable to determine the Conn-State.
Type Type of port, such as A—A port and B—B port.
Neig Type of port attached to this port. The neighbor can be one of these types:
• A—A port
• B—B port
• M—M port
• S—Slave port
• U—The concentrator cannot determine the type of the neighbor port.
Ler Con Status of whether the port is currently in a LER condition.
Est Estimated LER.
Alm LER at which a link connection exceeds the LER alarm threshold.
Cut LER cutoff value (the LER at which a link connection is flagged as faulty).
Lem-Ct Number of LEM errors received on the port.
