Chapter19 Configuring Circuit Emulation Services
Configuring CES T1/E1 Interfaces
Examples
The following example shows how to change the default cell delay variation for circuit0 to 30,000,
using the ces circuit command:
Switch# configure terminal
Switch(config)# interface cbr 3/0/0
Switch(config-if)# shutdown
Switch(config-if)# ces circuit 0 cdv 3000
Switch(config-if)# no shutdown
Note You must use the shutdown command to shut down the interface before you can modify the circuit. After
modifying the circuit, use the no shutdown command to reenable the interface.
Switch(config-if)# ces pvc circuit-id
dest-address atm-address [[vpi vpi] vci vci]
[retry-interval [first retry-interval]
[maximum retry-interval]] [follow-ifstate]
Configures the destination (active) port for the
circuit and configures a softPVC, as follows:
•Specifies the circuit identification.
–
For unstructured service, use 0.
–
For T1 structured service, use
1 through 24.
–
For E1 structured service, use
1 through 31.
•Specifies the destination address of the
soft PVC.
•Specifies the virtual path identifier of the
destination PVC.
•Specifies the virtual channel identifier of the
destination PVC.
•Configures retry interval timers for a softPVC,
as follows:
–
Specifies in milliseconds, the retry interval
after the first failed attempt. Thedefault
is 5,000.
–
Specifies in seconds, the maximum retry
interval between any two attempts. The
default is 600.
•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.
Step13 Switch(config-if)# ces pvc circuit-id
follow-ifstate
Configures the destination (passive) port circuit
status for a soft-PVC to follow the status of the
physical interface. The default circuit setting
ignores the status of the physical interface.
Step14 Switch(config-if)# no shutdown Reenables the interface.
