PoS Commands
configure aps
configure aps <group#> [nonrevert | revert <minutes>]
Description
Configures APS operation in either nonrevertive or revertive switching mode.
Syntax Description
Default
The default mode is
nonrevertive
switching.
Usage Guidelines
You specify the
group#
parameter, which is an integer in the range [1-65535]. The
group#
identifies the
APS group that the configuration command applies to. The default mode is
nonrevertive
switching.
This parameter determines what action should be taken when traffic is active on the protection line and
the working line becomes operational. In
revertive
mode, traffic will automatically be switched from
the protection line to the working line, after the user-defined wait-to-restore (WTR) period, which may
be specified via the
minutes
parameter. The WTR period is intended to prevent frequent switches due
to intermittent errors on the working line; service is restored only if no errors are detected on the
working line during the WTR period. The minutes parameter is an integer in the range [0-12].
Conversely, in nonrevertive mode, traffic will remain on the protection line (until either manual
intervention or a failure on the protection line forces a switch back to the working line). This parameter
is only applicable to SONET ports performing the protection line function.
Example
The following command configures an APS operation on group
1001
in revertive switching mode for 5
minutes:
configure APS 1001 revert 5
