Responding to a Failed prom Command

If you reboot after the prom command fails, a Bay Networks representative must

reinsert new PROMs (programmable, read-only memory chips) on the board and

rewrite the PROM software to them before the router can recover.

Getting Acquainted with the Troubleshooting Tools

Troubleshooting is much more complicated when you have to solve a problem

that requires an urgent solution and at the same time learn the how to use the tools

you need to solve the problem. Read this section and familiarize yourself with the

tools before you begin troubleshooting. The instructions later in this manual

assume you can use the tools identiﬁed in this section.

This chapter includes the following sections:

•“Using the System Lo

g to Display Event Messages”

•“Displa

ying and Changing Conﬁguration Settings and Statistics”

•“Using Ping

”

•“Using P

acket Capture”

•“Using Inbound

Telnet to Access the Technician Interface”

Using the System Log to Display Event Messages

The processor running software in each slot maintains its own log ﬁle in local

memory. Software entities (such as CSMACD and IP) report messages when

routine and noteworthy events occur. When you command Site Manager or the

Technician Interface to display the messages, the router automatically assembles

the messages from all slots into a single ﬁle and displays the ﬁle. Use the

messages in this ﬁle to diagnose a problem with a port, slot, router, or protocol.

Caution:

If the Technician Interface

prom

command fails, do not reboot.

Instead, call the Bay Networks Technical Response Center.
