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 fail-
ure.
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 configura-
tions on the peer. This means that the working circuit on the 7750 SR must be connected to the peer's work-
ing 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' mes-
sages sent by both protect and working circuits to their neighbor for multi-chassis APS.
