Troubleshooting a Token Ring Connection

This section assumes that you have isolated a problem to a Token Ring

connection. If not, refer to Chapter 2 to determine whether these instructions

apply to your problem.

Troubleshoot Token Ring as follows:

1. Filter the log to display only messages from the Token Ring entity

running on the slots experiencing the problem. The Technician Interface

command is

log -fftwid -eTOKEN -s

<slot_no.>

Example

If you are ﬁltering events from Slots 3 and 4, you enter

log -fftwid -eTOKEN -s3 -s4

If Token Ring Debug Event 36 (“Connector MAU<SlotConnector> Ring

Status Change<4_digit_hex_code>)” appears, convert the 4-digit number

from hexadecimal to binary. Assign the position numbers 0 through 10 to the

ﬁrst 11 digits from left to right. Look for the position number of the “1” bit in

the following list:

• 0 indicates signal loss.

• 1 indicates a hardware error.

• 2 indicates a software error.

• 3 indicates a transmitter beacon.

• 4 indicates a lobe wire fault.

• 5 indicates an automatic removal error.

• 6 is reserved for future use.

• 7 indicates a remove received.

• 8 indicates a counter overﬂow.

• 9 indicates a single station.

• 10 indicates a ring recovery.
