The no form of this command restores the default (non-revertive mode).
Default The default is to not revert back unless the protect circuit fails or operator intervention.
Parameters minutes — Specify the time, in minutes, to wait before reverting back to the original working circuit after it
has been restored into service.
Values 0— 60 minutes
Default 5
switching-mode
Syntax switching-mode {uni-1plus1 (R8.0)| bi-directional | uni-directional}
Context config>port>aps
Description This command configures the switching mode for the APS group.
Parameters bi-directional — Configures the group to operate in Bidirectional 1+1 Signalling APS mode.
uni-directional — Configures the group to operate in Unidirectional 1+1 Signalling APS mode.
uni-1plus1 — Configures the group to operate in Unidirectional 1+1 Signalling and Datapath APS mode
(7750 SR-c4/c12 platforms only).
working-circuit
Syntax working-circuit port-id [number number]
Context config>port>aps
Description This command configures a physical port that will act as the working circuit for this APS group. The work-
ing circuit port must contain only the default configuration and cannot be part of another APS group. The
working circuit must be created before the protection circuit.
When a port is a working circuit of an APS group, the configuration available under config>port port-id
context (including submenus) is not allowed for that port unless it is a part of the noted exceptions.
When a port is being configured as a working circuit of an APS group, all common configuration as
described above and all service configurations related to the APS port is operationally inherited by the work-
ing circuit from the aps-group-id. If the working circuit cannot inherit that configuration, for example, due to
resource limitations, the configuration attempt fails and an error is returned to the user.
Before a working circuit can be removed from an APS group, the working circuit port must be shutdown.
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.
Note that all configurations for aps-group-id under the config>port context and its submenus and all config-
uration for services that use this aps-group-id is preserved as a non-activated configuration since the APS
group no longer has any physical circuits assigned.
