Using the GWCON Interface Command

Maint: Fail

Number of maintenance failures

The following section describes the statistics displayed that are speci®c to the Token-Ring interfaces:

Physical address

Speci®es the physical address of the Token-Ring interface.

Network speed

Speci®es the speed of the Token-Ring network that connects to the interface. The Network Speed counter displays the number of packets that the interface can pass per second.

Max packet size (info)

Displays the maximum packet size con®gured for that interface. The Max Packet Size counter displays the maximum length, in bytes, of a packet that the interface transmits or receives. This counter is user-de®ned.

Handler state

Displays the current state of the Token-Ring handler. The Handler state counter displays the state of the handler after the self-test runs.

Ring status

Last Ring Status of the Token Ring interface.

SIGL	SIGNAL_LOSS	The interface has detected a loss of signal on the
	ring.
HERR	HARD_ERROR	The interface is presently transmitting or receiving
	beacon frames on the ring.
SERR	SOFT_ERROR	The interface has transmitted a report error MAC
	frame.
BEAC	TRANSMIT_BEACON			The interface is transmitting beacon
	frames to or from the ring.
LWF	LOBE_WIRE_FAULT		The interface has detected an open or
	short circuit in the cable between the interface and the wiring
	concentrator. The interface is closed and is at the state following
	initialization.
ARMV AUTO_REMOVAL_ERROR The interface has failed the lobe
	wrap test, which resulted from the beacon auto-removal process,
	and has removed itself from the ring. The interface has closed and
	is at the state following initialization.
RMVD REMOVED_RECEIVED				The interface has received a remove
	ring station MAC frame request and has removed itself from the
	ring. The interface is closed and is at the state following
	initialization.
CO	COUNTER_OVERFLOW			One of the following error counters has
	incremented from 254 to 255: Line, ARI/FCI, Frame Copy, Lost
	Frames, Burst, Lobe wire faults, Removes received. This display
	shows these error counters.
SSTA	SINGLE_STATION		The interface has sensed that it is the only
	station on the ring.
RR	RING_RECOVERY		The interface observes claim Token MAC
