Step 5 Use the show atm interface atm card/subcard/port command to display the configuration of the
ATM switch router RsalFl1Ls1, located in the remote sales building at subinterface 4/0/0.99:
RsalFl1Ls1# show atm interface atm 4/0/0.99
Interface: ATM4/0/0.99 Port-type: vp tunnel
IF Status: UP Admin Status: up
Auto-config: enabled AutoCfgState: waiting for response from peer
IF-Side: Network IF-type: UNI
Uni-type: Private Uni-version: V3.0
Max-VPI-bits: 0 Max-VCI-bits: 14
Max-VP: 0 Max-VC: 16383
Signalling: Enabled
ATM Address for Soft VC: 33.3333.3333.3333.3333.3333.3333.3333.3333.00
Configured virtual links:
PVCLs SoftVCLs SVCLs Total-Cfgd Installed-Conns 4 0 0 4

RsalFl1Ls1#
Step 6 Check the IF Status field to confirm the interface is up. If it is not, see Chapter 5, “Troubleshooting
Switch Router ATM Interface Connections.”
Step 7 Check the Admin Status field to confirm the interface is up. If it is not, see Chapter 5, “Troubleshooting
Switch Router ATM Interface Connections.”
Step 8 Check the Interface and ATM address for Soft VC fields. These values indicate that the VP tunnel is
configured correctly.
If you determine that the PVP is not configured correctly, see the “Configuring Virtual Connections”
chapter in the ATM Switch Router Software Configuration Guide.
Continue with the next phase of VP tunnel troubleshooting if you still have not determined the problem.
Checking Virtual Path PVP Configuration
To confirm the ATM virtual connection (VC) interface configuration, use the following command:
The following example shows how to confirm the configuration of ATM subinterface 1/0/0.99 on the
switch router AdminFl1Ls1 located in the administration building:
AdminFl1Ls1# show atm vc interface atm 1/0/0
Interface VPI VCI Type X-Interface X-VPI X-VCI Encap Status
ATM1/0/0 0 5 PVC ATM2/0/0 0 41 QSAAL UP
ATM1/0/0 0 16 PVC ATM2/0/0 0 33 ILMI UP
ATM1/0/0 99 40 PVC ATM4/0/0.99 99 50 UP
AdminFl1Ls1#
The interface ATM 1/0/0 field indicates that the cross-connect is configured correctly.
