Troubleshooting Soft PVC Connections
This section describes how to troubleshoot a soft PVC configuration. Soft PVCs are used primarily to
connect hosts that do not support signaling and cannot use SVCs.
In the example network in Figure 6-2, the connection between two User workstations across Switch B
and Switch C uses the following VPI and VCI numbers and ATM address:
• Switch B, ATM interface 0/0/2, VPI 0, and VCI 1000
• Switch C, ATM interface 1/1/1, VPI 0, VCI 1000, with an ATM address
47.0091.8100.0000.00e0.4fac.b410.4000.0c80.0910.00
Figure 6-2 Soft PVC Test in the Example Network
This section contains the following procedures:
• Checking the Interface Status
• Checking the VPI Number, VCI Number, and ATM Address
• Checking the Connection Management
• Debugging the Connection Management
For detailed information, see the “Configuring Virtual Connections” chapter in the
ATM Switch Router Software Configuration Guide.
Checking the Interface Status
Use the following command to check soft PVC connection interface status:
User A Switch B User DSwitch C
