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 switchedVC destination port, follow these
steps, beginning in privileged EXEC mode:
Example
The following example shows how to configure the destination (passive) side of an unstruct ured
switchedVC, as shown in Figure 19-8:
CESwitch# show ces status
Interface IF Admin Port Channels in
Name Status Status Type use
------------- -------- --------- ----------- -----------
CBR0/0/0 UP UP T1
CBR0/0/1 UP UP T1
CBR0/0/2 UP UP T1
CBR0/0/3 UP UP T1
CESwitch# configure terminal
CESwitch(config)# interface cbr 0/0/1
CESwitch(config-if)# shutdown
CESwitch(config-if)# ces aal1 service unstructured
CESwitch(config-if)# ces aal1 clock synchronous
Command Purpose
Step1 Switch# show ces status Displays information about current CBR
interfaces.
Use this command to choose the destination port.
Step2 Switch# configure terminal
Switch(config)#
At the privileged EXEC prompt, enters global
configuration mode.
Step3 Switch(config)# interface cbr card/subcard/port
Switch(config-if)#
Selects the physical interface to be configured.
Step4 Switch(config-if)# shutdown Disables the interface.
Step5 Switch(config-if)# ces aal1 service {structured |
unstructured}
Configures the CES interface AAL1 service type.
Step6 Switch(config-if)# ces aal1 clock {adaptive | srts
| synchronous}
Configures the CES interface AAL1 clock mode.
Step7 Switch(config-if)# ces dsx1 clock source
{loop-timed | network-derived}
Configures the CES interface clock source.
Step8 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.
Step9 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.
Step10 Switch(config-if)# no shutdown Reenables the interface.
