Syntax
[ default | no } preferred slot slot_number
default
Sets the port for non-revertive operation for port redundancy auto-recovery; requiring an administrative user
to manually issue a
to manually issue a
port switch to
command to return service to the original port.
no
Disables revertive, or auto-recovery, operation for selected port.
slot_number
Identifies the physical chassis slot where the SPIO card is installed.
Usage
This command enables or disables revertive port redundancy, wherein after a port failover, when the original
port is restored to service (such as 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.
This command must be issued on a per port basis, allowing you to configure specific ports to be used on
individual line cards or SPIO cards. For example, ports 1 through 4 could be configured as “preferred” on the
line card in slot 17, while ports 5 through 8 are “preferred” on the line card in slot 33. In this scenario, both
line cards would be in an Active operational state while still providing LC and port redundancy for the other.
