Configuring T1/E1 CES SVCs
Phase 2—Configuring the Source (Active) Side of the Structured Switched VC
The example connection shown in
Figure 19-9
is used in the following example configuration.
To configure a switched VC for structured CES, 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 structured
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
Switch(config-if)#

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.
Configures the 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.
Step 9

Configures the switched VC to the CBR
interface.
Step 10
Switch(config-if)#
no shutdown
Reenables the interface.
