Chapter19 Configuring Circuit Emulation Services
Configuring T1/E1 Structured (n x 64) Circuit Emulation Services
Example
The following example shows how to configure the source (active) side of a soft PVC for structured CES,
as shown in Figure 19-5:
CESwitch# show ces address
CES-IWF ATM Address(es):
47.0091.8100.0000.00e0.4fac.b401.4000.0c81.803c.10 CBR3/0/3:1 vpi 0 vci 3088
CESwitch# configure terminal
CESwitch(config)# interface cbr 3/0/0
CESwitch(config-if)# shutdown
CESwitch(config-if)# ces circuit 1 timeslots 1-3, 7
CESwitch(config-if)# ces circuit 1 circuit-name CBR-PVC-A
CESwitch(config-if)# ces pvc 1 dest-address
47.0091.8100.0000.0060.5c71.1f01.4000.0c80.1034.10 vpi 0 vci 16 follow-ifstate
CESwitch(config-if)# no shutdown
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 CBRx/y/z:# for the circuit being configured. For
example, the default name for this particular circuit is CBR3/0/0:1. For structured circuit emulation
services, the circuit number sequence always begins at 1 for each port in a CES module.
Step 5
Switch(config-if)# ces circuit circuit-id timeslots
number
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.
Note The 0 circuit identifier is reserved for
unstructured service.
• Time slots for the circuit for structured
service only.
–
For CES T1, the range is 1 through 24.
–
For CES E1, the range is 1 through 31.
Step 6
Switch(config-if)# ces circuit circuit-id
circuit-name name
Configures the CES interface circuit name.
Step 7
Switch(config-if)# ces pvc circuit-id
dest-address remote_atm_address vpi vpi vci vci
[follow-ifstate]
Configures the soft PVC to the destination
CES-IWF ATM addresses and VPI/VCI of the
circuit.
Use the VPI/VCI of the destination port that was
retrieved in Step 1.
The follow-ifstate keyword configures the source
(active) port circuit status to follow the status of
the physical interface. The default circuit setting
ignores the status of the physical interface.
Step 8
Switch(config-if)# no shutdown Reenables the interface.
