Configuring T1/E1 CES SVCs
Phase 1—Configuring the Destination (Passive) Side of the Unstructured Switched VC
To configure the destination (passive) side of an unstructured switched VC destination port, follow these
steps, beginning in privileged EXEC mode:
Example
The following example shows how to configure the destination (passive) side of an unstructured
switched VC, as shown in
Figure 19-8

Command
Purpose
Step 1
Switch#
show ces status
Displays information about current CBR
interfaces.
Use this command to choose the destination port.
Step 2
Switch#
configure terminal
Switch(config)#
At the privileged EXEC prompt, enters global
configuration mode.
Step 3
Switch(config)#
interface cbr
card
/
subcard
/
port
Switch(config-if)#
Selects the physical interface to be configured.
Step 4
Switch(config-if)#
shutdown
Disables the interface.
Step 5
Switch(config-if)#
ces aal1 service
{
structured
|
unstructured
}
Configures the CES interface AAL1 service type.
Step 6
Switch(config-if)#
ces aal1 clock
{
adaptive
|
srts
|
synchronous
}
Configures the CES interface AAL1 clock mode.
Step 7
Switch(config-if)#
ces dsx1 clock source
{
loop-timed
|
network-derived
}
Configures the CES interface clock source.
Step 8
Switch(config-if)#
ces circuit
circuit-id
circuit-name
name
Configures the CES interface circuit identifier
and circuit name.
Note
For unstructured service, use 0 for the
circuit identifier.
Step 9
Switch(config-if)#
ces svc
circuit-id
passive
follow-ifstate
Configures the destination (passive) port circuit
status to follow the status of the physical
interface. The default circuit setting ignores the
status of the physical interface.
Step 10
Switch(config-if)#
no shutdown
Reenables the interface.
