Configuring T1/E1 CES SVCs
Example
The following example shows how to configure the destination (passive) side of a switched VC for
structured T1 CES, as shown in
Figure 19-9

}
Switch(config-if)#
ces dsx1 linecode

}
Configures the CES T1 line code type. The
default is
b8zs
.
Configures the CES E1 line code type. The
default is
hdb3
.
Step 9
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.
•
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 10
Switch(config-if)#
ces circuit

Configures the CES interface circuit name.
Step 11
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 12
Switch(config-if)#
no shutdown
Reenables the interface.
