CESwitch(config-if)# ces dsx1 clock source network-derived
CESwitch(config-if)# ces circuit 0 circuit-name CBR-PVC-B
CESwitch(config-if)# no shutdown
Note If you do not specify the circuit name and logical name parameters in the command line, the system
automatically assigns a unique default name in the form CBRx/y/z:# for the circuit being configured. For
example, the default name for this particular circuit is CBR3/0/1:0.
Phase 2—Configuring the Source (Active) Side of the Soft PVC
To configure the source (active) side of a softPV C destination port, follow these steps, beginning in
privileged EXEC mode:
Command Purpose
Step1 Switch# show ces address Shows the CES address and VPI/VCI for the
destination end of the circuit.
Use this command to retrieve the destination’s
VPI/VCI.
Step2 Switch# configure terminal
Switch(config)#
At the privileged EXEC prompt, enters global
configuration mode.
Step3 Switch(config)# interface cbr card/subcard/port
Switch(config-if)#
Selects the physical interface to be configured.
Step4 Switch(config-if)# shutdown Disables the interface.
Step5 Switch(config-if)# ces aal1 service {structured |
unstructured}
Configures the CES interface AAL1 service type.
Step6 Switch(config-if)# ces aal1 clock {adaptive | srts
| synchronous}
Configures the CES interface AAL1 clock mode.
Step7 Switch(config-if)# ces dsx1 clock source
{loop-timed | network-derived}
Configures the CES interface clock source.
Step8 Switch(config-if)# ces circuit circuit-id
circuit-name name
Configures the CES interface circuit identifier
and circuit name.
Note For unstructured service, use 0 for the
circuit identifier.
Step9 Switch(config-if)# ces pvc circuit-id
dest-address remote_atm_address vpi vpi vci vci
[follow-ifstate]
Configures the softPVC to the destination
CES-IWF ATM addresses and VPI/VCI of the
circuit.
Note Use the destination’s VPI/VCI, which
you retrieved in Step 1.
The follow-ifstate keyword configures the source
(active) port circuit status to follow the status of
the physical interface. The default circuit setting
ignores the status of the physical interface.
Step10 Switch(config-if)# no shutdown Reenables the interface.
