Chapter 6: Initial Troubleshooting

The types of problems that typically occur with networks involve connectivity and performance. It is usually
best to follow the OSI network architecture layers. Confirm that the physical environment, such as the
cables and module connections, is operating without any failures before moving up to the network and
application layers.

Gather information

Before contacting Technical Support, you must gather information that can help the Technical
Support personnel. This includes the following information:
• Default and current configuration of the switch. To do this, you can use the show
running-config command.
• System status. Output from the show tech command. This command displays technical
information about the system status, as well as information about the hardware, software,
and switch operation. This command displays more information than the similar show
sys-info command.
• Information about past events. To do this, review the log files.
• The software version that is running on the device. To do this, use the show sys-info
or show system verbose commands to display the software version that is running
on all cards.
