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 “LEDs”
section on page 2-17.
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.
This chapter provides these topics for troubleshooting problems:
• Understanding POST Results, page 4-2
