APS Commands
The route to the neighbor must not traverse the multi-chassis APS member (working or protect) circuits. It is
recommended that the neighbor IP address configured is on a shared network between the routers that own
the working and protect circuits.
By default no neighbor address is configured and both the working and protect circuits should be configured
on the same router (i.e., single-chassis APS). APS is assumed to be configured wholly on a single chassis.
Parameters
ip-address — Specifies the neighbor's IP address only on a multi-chassis APS where the working and protect
circuits are configured on different routers. The node should be connected with a direct interface to
ensure optimum fail-over time.
Values
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:
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.
