Troubleshooting Channelized DS3 and E1 Frame Relay Interfaces
Follow these steps to display the memory management and error counters of a channelized DS3 or E1
Frame Relay interface:
Step 1 Use the show controllers atm card/subcard/port command to check memory management and error
counters.
Switch# show controller e1 1/0/1
E1 1/0/1 is up.

down
• Disconnected or faulty cabling
• Hardware failure
Check for the following:
• Check cables.
• Replace faulty hardware.
