protect-circuit
Syntax
protect-circuit
port-id
no protect-circuit
Context
config>port>aps
Description
This command configures a physical port that will act as the protection circuit for this APS group.
The protect circuit port must contain only the default configuration and cannot belong to another APS
group. The protect circuit port must be of the same type as the working circuit for the APS group, for
the port to be added to an APS group port. If that’s not the case, the command will return an error.
A protection circuit can only be added if the working circuit already exists; the protection circuit
must be removed from the configuration before the working circuit is removed.
When a port is a protect-circuit of an APS group, the configuration options available in the
config>port
port-id
>sonet-sdh
context is not allowed for that port unless it is part of the noted
exceptions. The exception list includes these SONET/SDH commands:
clock-source
[no] loopback
[no] report-alarm
section-trace
[no] threshold
When is port configured as a protection circuit of an APS group, the configurations described above
and all service configurations related to APS port are operationally inherited by the protect circuit. If
the protect circuit cannot inherit the configurations (due to resource limitations), the configuration
attempt fails and an error is returned to the user.
The protect circuit must be shutdown before it can be removed from the APS group port. The
inherited configuration for the circuit and APS operational commands for that circuit are not
preserved when the circuit is removed from the APS group.
The
no
form of this command removes the protect-circuit.
Default
none
Parameters
port-id —
Specify the physical port that will act as the protection circuit for this APS group in the
slot
