Configuring Switching Between the Working and Protect Circuits

 

You can perform a manual switch between the working and protect circuits.

  1. In configuration mode, go to the [edit interfaces interface-name sonet-options aps] hierarchy level.
  2. Configure the request option as protect or working to perform a manual switch. This option is honored only if there are no higher-priority reasons to switch.

To switch the circuit manually to being the working circuit or to override the revert timer when the working circuit is operating in nonrevertive mode:

  1. In configuration mode, go to the [edit interfaces interface-name sonet-options aps] hierarchy level.
  2. Configure the request working option to switch the circuit manually to being the working circuit or to override the revert timer when the working circuit is operating in nonrevertive mode.

To perform a forced switch:

  1. In configuration mode, go to the [edit interfaces interface-name sonet-options aps] hierarchy level.
  2. Configure the force option to perform a forced switch. This option is honored only if there are no higher-priority reasons to switch. This configuration can be overridden by a signal failure on the protect circuit, thus causing a switch to the working circuit.

To configure a lockout of protection, forcing the use of the working circuit and locking out the protect circuit regardless of anything else.

  1. In configuration mode, go to the [edit interfaces interface-name sonet-options aps] hierarchy level.
  2. Configure a lockout of protection, forcing the use of the working circuit and locking out the protect circuit regardless of anything else.

To display an Annex B lockout configuration, use the show aps extensive operational command.
