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

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 CBR
x/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)#

Configures the CES interface circuit name.

[
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.
