preferred slot
Identifies which card in a chassis should assume revertive (redundancy auto-recovery) functionality should the slot/port
being configured go down. This command must be issued on a per port basis, allowing you to configure specific ports to
be used on individual LCs or SPIO cards. For example, ports 1 through 4 could be configured as “preferred” on the LC
in slot 17 while ports 5 through 8 are “preferred” on the LC in slot 33. In this scenario, both LCs would be in an Active
operational state while still providing LC and port redundancy for the other.

Disables revertive, or auto-recovery, operation for the port.
Usage
This command enables or disables revertive port redundancy. So after a port failover, when the original port
is restored to service (i.e. link up) the system will return service to that port automatically.
Disabled, which is the default setting, causes non-revertive operation; requiring an administrative user to
manually issue a port switch to command to return service to the original port.
