Chapter 5 Troubleshooting Switch Router ATM Interface Connections
Troubleshooting 155-Mbps and 622-Mbps Interfaces
• Cable damage. If you are using UTP cables, make sure you are using category 5 cables and not
another type, such as category 3.
If you determine that the physical interface is configured incorrectly, refer to the “Configuring
Interfaces” chapter in the ATM Switch Router Software Configuration Guide.
Follow these steps to display the memory management and error counters of a 155-Mbps or 622-Mbps
ATM interface:
Step 1 Use the show controllers atm card/subcard/port command to check memory management and error
counters.
