Verifying a Hard PVC for Unstructured CES
To verify the hard PVC configuration, use the following privileged EXEC commands:
Examples
The following example shows how to display the basic information about the hard PVC shown in
Figure 19-1, using the show ces circuit command:
CESwitch# show ces circuit
Interface Circuit Circuit-Type X-interface X-vpi X-vci Status
CBR3/0/0 0 HardPVC ATM0/1/3 0 100 UP
The output from this command verifies the source (CBR 3/0/0) and destination (ATM 0/1/3) port IDs of
the hard PVC and indicates that the circuit is up.
The following example shows how to display detailed information about the hard PVC shown in
Figure 19-1, using the show ces circuit interface command:
CESwitch# show ces circuit interface cbr 3/0/0 0
Circuit: Name CBR-PVC-A, Circuit-state ADMIN_UP / oper-state UP
Interface CBR3/0/0, Circuit_id 0, Port-Type T1, Port-State UP

HardPVC
src: CBR3/0/0 vpi 0, vci 16
Dst: ATM0/1/3 vpi 0, vci 100
The output from this command verifies the following configuration information:
• The circuit named CBR-PVC-A is in an UP state.
• The interface CBR 3/0/0 has a circuit id of 0 (because the entire bandwidth of the port is dedicated
to that circuit).
• The AAL1 clocking method is adaptive clocking.
• The source port for the hard PVC is CBR 3/0/0. The destination port is ATM 0/1/3.
Configuring a Soft PVC for Unstructured CES
In a soft PVC, as well as a hard PVC, you configure both ends of the CES circuit. However, a soft PVC
typically involves CES modules at opposite edges of an ATM network, so a soft PVC can be set up
between any two CES modules anywhere in your network.
