Error Statistics

The Ethernet or Token Ring Error Statistics Display provides a detailed

summary of the receiver and transmitter errors that have occurred on the

unit. To access this display, select Statistics from the Main Menu then

select Ethernet or Token Ring from the Statistics Menu.

Token Ring Error Statistics

n Invalid frame received: The Token Ring adapter has received a

frame that was either marked bad in its trailer, had a bad CRC, or

had code violations during the reception of the packet contents.

n Line burst error: The Token Ring adapter had detected illegal

sequence of bits inside a received frame indicating the frame was

corrupted.

n ARI/FCI Error: The Token Ring adapter has detected a loss of sig-

nal on the ring.

n Lost frame error: The Token Ring adapter has transmitted a frame

and failed to see it come back around the ring to be stripped.

n Receiver congested: The Token Ring adapter had no buffer space to

receive a frame from the ring. This is likely due to an excessive

amount of trafﬁc forwarded across the radio, thereby causing a

backlog.
