APS Commands
aps
Syntax
aps
Context
config>port
Description
This command configures APS (Automatic Protection Switching). APS is used by SONET/SDH add/drop
multiplexers (ADMs) or other SONET/SDH-capable equipment to protect against circuit or equipment
failure.
An APS group contains a working and a protect circuit and can span a single node (SC-APS) or two nodes
(MC-APS).
The working and protection configurations on Alcatel-Lucent 7750 SRs must match the circuit
configurations on the peer. This means that the working circuit on the 7750 SR must be connected to the
peer’s working circuit and the protect circuit must be connected to the peer’s protection circuit.
The
aps
command is only available for APS groups and not physical ports.
Default
none
advertise-interval
Syntax
advertise-interval advertise-interval
no advertise-interval
Context
config>port>aps
Description
This command specifies the time interval, in 100s of milliseconds, between 'I am operational' messages sent
by both protect and working circuits to their neighbor for multi-chassis APS.
The
advertise-interval
value is valid only for a multi-chassis APS as indicated by the value of the
neighbor
command value if it is not set to 0.0.0.0.
Default
10
Parameters
advertise-interval —
Specifies the time interval, in 100s of milliseconds, between 'I am operational'
messages sent by both protect and working circuits to their neighbor for multi-chassis APS.
Values
10 — 650
