Troubleshooting Two-Ended Soft PVC Connections
Step 2 Check the Remote ATM address. This address should match the ATM address at the other end of the soft
PVC connection.
Step 3 Check the VPI and VCI fields. They indicate the VPI and VCI configuration of this interface.
Step 4 Check the Remote VPI and Remote VCI fields. They indicate the VPI and VCI configuration of the
interface in the e-mail server.
If you determine that the VPI and VCI configurations are incorrect, see the “Configuring Virtual
Connections,” of the ATM Switch Router Software Configuration Guide.
Step 5 Check the Soft vc call state field. This field should be Active.
Step 6 Check the Number of soft vc re-try attempts field. The number should be 0.
Checking the Connection Management
Use the following command to check soft PVC connection management:
Debugging the Connection Management
Use the following commands to debug the PVC connection management:
Troubleshooting Two-Ended Soft PVC Connections
Two-ended soft PVC provisioning allows you to configure the passive half-leg (destination end) of a soft
PVC. This allows the destination end to be pre-configured for use when the soft PVC is set up. The
passive leg is used during soft PVC setup, provided the traffic parameters of the leg match the incoming
connection setup request, and the leg is in a “Not Connected” state. If the passive leg is not
pre-configured, the default values are used when creating the dynamic leg.
This provides the destination-end connection administrator the following advantages when the soft PVC
is configured:
• Resources on the terminating switch are reserved for the incoming soft PVC
• The UPC option can be configured for an individual soft PVC allowing traffic policing
