Chapter 9: Token Ring Problems

9-6 Troubleshooting Guide

9.4 There Is a Constant Stream of Burst Errors on the Network

Burst errors are a normal occurrence when users are inserting onto a ring. If the burst errors continue after everyone is

logged on, then there is a problem.

To determine which station is reporting burst errors, check the station statistics using SPEL.

Did you find which station is reporting the burst errors?

Call Cabletron Technical Support.

The problem station can be either the station upstream from the station reporting the errors, or the receiver in the station

reporting the errors.

NOTE: Burst errors may be reported by stations further down the ring. This is a normal occurrence, but

by carefully looking at each station that is reporting the burst errors and seeing where the first station is

that starts reporting them, you can isolate it to one station.

Did you locate the station that first started to report the burst errors?

Call Cabletron Technical Support.

Remove its upstream neighbor from the ring.

Did this action solve the problem?

Remove the station reporting the burst errors.

Did this action solve the problem?

Call Cabletron Technical Support.

Reboot the station and insert it onto the ring.

Did this action solve the problem?

The interface card in the station being rebooted may need to be replaced if it continually causes bursts. Replace the

station interface card with a known good one. Reboot and reinsert the station on the ring.

Did this correct the problem?

Call Cabletron Technical Support.

Congratulations, the problem is solved.
