Item

Description

Protection Groups

Lists the protection groups that have been created on the node.

Selected Group

Displays the slot and cards that are in the protection group and their protection status, either Protect or Working.

Switch Commands

Manages protection group switch commands:

  • Clear: Clears a traffic switch on the card or port highlighted under Selected Group.

  • Switch: (1:1 protection groups only) Switches traffic from the highlighted working card or port to the protect card or port.

  • Manual: (1+1 protection groups only) Initiates a manual switch on the selected port. This command switches traffic only if the path has an error rate less than the signal degrade (SD) bit error rate threshold.

  • Force: (1+1 protection groups only) Initiates a forced switch on the selected port. This command switches traffic even if the path has SD or signal fail (SF) conditions. A Force switch has a higher priority than a Manual switch.

Inhibit Switching

Manages protection group lock out commands:

  • Unlock: Clears a lock out.

  • Lock Out: Prevents traffic from being switched to the card. Lockouts can only be applied to protect cards (in 1+1 configurations) and prevent traffic from switching to the protect port under any circumstance. Lockouts have the highest priority.

  • Lock On: Locks traffic onto the working card, that is, prevents a traffic switch from occurring. In a 1+1 configuration you can also apply a lock on to the working port. A working port with a lock on applied cannot switch traffic to the protect port in the protection group (pair).
