Troubleshooting a Data Link Layer Problem

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 a token ring connection 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 as follows:
log -fftwid -eTOKEN -s
<slot_no.>
Example
If you are filtering events from slots 3 and 4, enter the following command:
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.
