Configuring T1/E1 Structured (n x 64) Circuit Emulation Services
Example
The following example shows how to enable channel-asso ciated signalling (CAS) on a soft PVC
(see Figure 19-6):
CESwitch# show ces status
Interface IF Admin Port Channels in
Name Status Status Type use
------------- -------- --------- ----------- -----------
CBR3/0/0 UP UP T1 1-3,7
CBR3/0/1 DOWN UP T1
CBR3/0/2 DOWN UP T1
CBR3/0/3 UP UP T1 10-13
CESwitch# configure terminal
CESwitch(config)# interface cbr 3/0/0
CESwitch(config-if)# shutdown
CESwitch(config-if)# ces dsx1 signalmode robbedbit
CESwitch(config-if)# ces circuit 1 cas
CESwitch(config-if)# no shutdown
CESwitch(config-if)# exit
CESwitch(config)# interface cbr 3/0/3
CESwitch(config-if)# shutdown
CESwitch(config-if)# ces dsx1 signalmode robbedbit
CESwitch(config-if)# ces circuit 1 cas
CESwitch(config-if)# no shutdown
Verifying a Soft PVC for Structured CES with CAS Enabled
To verify the softPVC with structure d CES and CAS enabled, use the following EXEC commands:
Examples
The following example displays the details of the CES circuit (shown in Figure19-6), using the show ces
circuit command at the privileged EXEC mode prompt:
CESwitch# show ces circuit
Interface Circuit Circuit-Type X-interface X-vpi X-vci Status
CBR3/0/0 0 Active SoftVC ATM-P3/0/3 0 16 UP
CBR3/0/1 0 Passive SoftVC ATM-P3/0/3 0 1040 UP
The following example displays the CAS status for the source port CBR 3/0/0 (shown in Figure 19-6):
CESwitch# show ces circuit interface cbr 3/0/0 1
