Using the GWCON Interface Command

frames on the ring. The interface may be transmitting the claim Token frames. This status remains until the interface transmits a ring purge frame.

Interface Restarts

Speci®es the number of times the Token Ring chip timed out, or the Token Ring driver received a bad command from the handler. For information about why a restart occurred, see messages TKR.37, TKR.38, TKR.39, TKR.40, and TKR.41. in Event Logging System Messages Guide

# of times signal lost

Speci®es the total number of times that the router was unable to transmit a packet due to loss of signal.

Hard errors

Displays the number of times the interface transmits or receives beacon frames from the network.

Auto-removal errors

Displays the number of times the interface, due to the beacon auto-removal process, fails the lobe wrap test and removes itself from the network.

Ring recovery actions

Displays the number of times the interface detects claim token medium access control (MAC) frames on the network.

Line errors

The Line Errors counter increments when a frame is repeated or copied and the Error Detected Indicator (EDI) is zero for the incoming frame:

One of the following conditions must also exist:

vA token with a code violation exists.

vA frame has a code violation between the starting and ending delimiter.

vA Frame Check Sequence (FCS) error occurs.

ARI/FCI errors

The ARI/FCI (Address Recognized Indicator/Frame Copied Indicator) Errors counter increments if the interface receives either of the following:

An Active Monitor Present (AMP) MAC frame with the ARI/FCI bits equal to zero and a Standby Monitor Present (SMP) MAC frame with the ARI/FCI bits equal to zero.

More than one SMP MAC frame with the ARI/FCI bits equal to zero, without an intervening AMP MAC frame.

This error indicates that the upstream neighbor copied the frame but is unable to set the ARI/FCI bits.

Frame copy errors

Displays the number of times the interface in receive/repeat mode recognizes a frame addressed to its speci®c address but ®nds the address recognize indicator (ARI) bits not equal to zero. This error indicates a possible line hit or duplicate address.

Lost frames

Displays the number of times the interface is in transmit mode (stripping) and fails to receive the end of a transmitted frame.

# times beaconing

Displays the number of times the interface transmits a beacon frame to the network.
