Troubleshooting ATM E1/T1 interfaces
You can start troubleshooting an ATM interface by testing network connectivity using the ping command
or the extended ping command. In an extended ping command, specify some options in the IP header.
For more information about the ping command, see Network Management and Monitoring
Configuration Guide.
If the interface cannot be pinged, check whether:
•
The interface is down.
The AAL5 encapsulation type of the PVC is incorrect.
•
Configuring an ATM OC-3c/STM-1 interface
Overview
This section covers only the physical configurations of the interface. For more information about how to
configure ATM (including PVCs), see Layer 2—WAN Configuration Guide.
