Configuring APS Parameters

NOTE: It is recommended to group working lines and protect lines on separate IOMs.

The following displays an APS working configuration:

A working port must be added first. Then a protection port can be added or removed at any
time.
A protection port must be shutdown before being removed from an APS group.
A path cannot be configured on a port before the port is added to an APS group.
A working port cannot be removed from an APS group until the APS port path is
removed.
When ports are added to an APS group, all path-level configurations are available only on
the APS port level and configuration on the physical member ports are blocked.
For a multi-chassis APS group, only one member circuit (either working or protect) can be
added. Note that the neighbor IP address of an APS group must be configured before
adding a member circuit in it. The configuration of a non-zero neighbor IP address
indicates the APS group as multi-chassis. Thus, the member circuit and services must be
removed before adding or removing the neighbor IP address (for example, before
converting an APS group from multi-chassis to single-chassis or single-chassis to multi-
chassis).
Bundle Protection Group (BPGrp) - A BPGrp is a collection of two bundles created on the
APS Group port. Working bundle resides on the working circuit of the APS group, while
protection bundle resides on the protection circuit of the APS group. APS protocol
running on the circuits of the APS Group port monitors the health of the Sonet/SDH line
and based on it or administrative action moves user traffic from one bundle to another in
the group as part of an APS switch.
