Chapter 9. Nortel Networks Layer 2/3 GbE Switch Module troubleshooting
157
9.2 Nortel Networks L2/3 GbESM troubleshooting methodology
In this section, we discuss general troubleshooting techniques and offer options for getting
started.
9.2.1 General comments on troubleshooting
Because of the highly integrated nature of the Nortel Networks L2/3 GbESM within the
IBM
Eserver
BladeCenter, it is usually necessary to engage several teams for anything
beyond basic hardware troubleshooting. Experience has shown that the greater the
communication between administrative groups, the more likely an issue can be resolved
sooner rather than later.
Where do you start when troubleshooting? How do you determine whether it is a hardware or
configuration issue and not a software bug?
The only true answer is
experience
.
Rather than attempting to list step-by-step procedures for every possible troubleshooting
issue (which could fill several volumes and still not be complete), this section offers
information about what to gather and commands that can be useful. The information here
assumes that the person doing the troubleshooting has experience in such matters.
