210 Cisco Systems Intelligent Gigabit Ethernet Switch Module
To execute different levels of diagnostics, log into the MM GUI and go to I/O Module tasks.
Under Power/Restart, select one of the following options:
1. Run Standard Diagnostics
Usually takes less than two minutes to test and complete boot; it runs:
– Flash memory test
– CPU cache memory test
– DRAM test
– Data path test
–ASIC test
2. Run Extended Diagnostics
Usually takes less than five minutes and runs the regular POST tests plus:
– Extended DRAM test
3. Run Full Diagnostics
Usually takes less than 12 minutes and runs the regular POST and extended POST, plus:
– Extended Flash test
8.4 Troubleshooting suspected software issues
The best approach to troubleshooting possible software issues is to obtain the readme file for
the latest IGESM code to see whether the issue you are encountering is covered.
If a documented bug is found, upgrading to the newer code should resolve the issue. You also
might want to upgrade to newer code to take advantage of new features in the upgraded
code. For example, version 12.1(14)AY4 and later has trunk failover and improved
Etherchannel load balancing.
If you believe that you have encountered a new (undocumented) bug, you should work with
technical support to engage necessary resources to resolve this issue.
8.5 Troubleshooting suspected configuration issues
Configuration issues are probably the most common troubleshooting event, and they usually
require close cooperation among administrative groups. Some common tools that are
available for this sort of troubleshooting are:
򐂰 IOS Command Line Interface
Familiarity with the IGESM IOS CLI is imperative.
򐂰 Management Module GUI interface
Understanding the Management Module GUI is very useful to aid in troubleshooting.
򐂰 OS-based commands
Most operating systems support network troubleshooting commands, and some form of
ping, arp dump, and traceroute commands are available in all major operating systems.
򐂰 External network management software
CiscoWorks, IBM Director, and other management platforms can be used to gather data
and help isolate problems.
򐂰 Other third-party tools include a network sniffer tool for capturing and examining network
traffic, and a ping sweep tool for rapidly testing connectivity at many levels.
The following groups of IOS CLI commands all run from Enable mode except where noted.
