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 CBR
x/y/z:#
for the circuit being configured. For
example, the default name for this particular circuit is CBR0/0/1:0.
Phase 2—Configuring the Source (Active) Side of the Unstructured Switched VC
To configure the source (active) side of an unstructured switched VC destination port, follow these steps,
beginning in privileged EXEC mode:
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 ces address
Shows the CES address and VPI/VCI for the
destination end of the circuit.
Step 3
Switch#
configure terminal
Switch(config)#
At the privileged EXEC prompt, enters global
configuration mode.
Step 4
Switch(config)#
interface cbr
card
/
subcard
/
port
Switch(config-if)#
Selects the physical interface to be configured.
Step 5
Switch(config-if)#
shutdown
Disables the interface.
Step 6
Switch(config-if)#
ces aal1 service unstructured
Configures the CES interface AAL1 service type.
Step 7
Switch(config-if)#
ces aal1 clock
{
adaptive
|
srts
|
synchronous
}
(Optional) Configures the AAL1 clock mode.
Step 8

Configures the following CES connection
attributes for the circuit:
Circuit id number 0 and circuit name.
Enables channel-associated signalling for
structured service only. The default is no
cas
.
Enables the peak-to-peak cell delay variation
(CDV) requirement. The default is 2000
milliseconds.

Configures the switched VC to the CBR
interface.
Step 10
Switch(config-if)#

Reenables the interface.
