Phase 2—Configuring a Hard PVC
To configure a hard PVC, follow these steps:
Command Purpose
Step 1
Switch# show ces status Displays information about the current CBR
interfaces.
Use this command to choose the source CBR
port.
Step 2
Switch# show atm status Displays information about the current ATM

Step 7
Switch(config-if)# ces circuit circuit-id
[timeslots number]
Configures the following CES connection
attributes for the circuit:
• Circuit id number.
– For CES T1 structured service,
use 1 through 24.
– For CES E1 structured service,
use 1 through 31.
Note The 0 circuit identifier is reserved for
unstructured service.
