Configuration Commands
Page 316 7750 SR OS Interface Configuration Guide
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
Context config>port>aps
Description This command configures a physical port that will act as the working circuit for this APS group. The
working 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 working 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
configuration 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.
The no form of this command removes the working-circuit. The working circuit can only be removed
from the configuration after the protect circuit has been removed.
