Troubleshooting

The front-panel LEDs provide troubleshooting information about the switch.
They show power-on self-test (POST) failures, port-connectivity problems, and
overall switch performance. For a full description of the LEDs, see the
section on page
You can also get statistics from the Cluster Management Suite (CMS), the
command-line interface (CLI), the Cisco Intelligence Engine 2100 (IE2100)
Series Configuration Registrar, or a Simple Network Management Protocol
(SNMP) workstation. Refer to the switch software configuration guide, the switch
command reference, or the documentation that came with your IE2100 or SNMP
application for details.
