Troubleshooting Channelized DS3 and E1 Frame Relay Interfaces
Table 5-1 describes the Port status and Active defect errors the might appear, the cause of the error, and
a recommended solution.
If you determine that the physical interface is configured incorrectly, refer to the Configuring
Interfaces chapter in the ATM Switch Router Software Configuration Guide.
If the configuration of the interface is not the problem, use the information in OAM Loopback Testing,
page 5-9 to configure a hard loopback to test the interface.
Next, see the Using the debug Commands to Troubleshoot an Interface, page 5-19 to further troubleshoot
the interface.
If the interface is still not operating correctly, proceed with the troubleshooting process in Chapter 6,
Troubleshooting Switch Router ATM Network Connections.
