Troubleshooting
This chapter describes how to identify and resolve software problems related to the Cisco IOS software
on the switch. Depending on the nature of the problem, you can use the command-line interface (CLI),
the device manager, or Network Assistant to identify and solve problems.
Unless otherwise noted, the term switch refers to a standalone switch and to a switch stack.
Additional troubleshooting information, such as LED descriptions, is provided in the hardware
installation guide.
