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)# ces circuit circuit-id [cas]
[cdv max-req] [circuit-name name] [partial-fill
number] [shutdown] [timeslots number]
[on-hook-detect pattern]
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
Switch(config-if)# ces svc circuit-id dest-address
atm-address [hold-priority priority]
[follow-if-state] [retry-interval [first
retry-interval] [maximum retry-interval]]
Configures the switched VC to the CBR
interface.
Step 10
Switch(config-if)# no shutdown Reenables the interface.
