Troubleshooting Gigabit Ethernet Interface Modules
Follow these steps to troubleshoot the status of a Gigabit Ethernet interface module:
Step 1 Use the show controllers GigabitEthernet card/subcard/port command to check the configuration.
Note The Catalyst 8540 CSR has no switch feature card. Consequently, you can not check the number of
cells switched on an individual VC.
