Setting Port Priority Levels

As not all Powered Devices (PDs) connected to the switch have the same priority within a customer

network setting, the switch allows the user to specify priority levels on a port-by-port basis. Priority levels

include low, high, and critical. The default priority level for a port is low.

• Low. This default value is used for port(s) that have low-priority devices attached. In the event of a

power management issue, inline power to low-priority is interrupted first (i.e., before critical and high-

priority).

• High. This value is used for port(s) that have important, but not mission-critical, devices attached. If

other in the chassis have been configured as critical, inline power to high-priority is given second

priority.

• Critical. This value is used for port(s) that have mission-critical devices attached, and therefore require

top (i.e., critical) priority. In the event of a power management issue, inline power to critical is

maintained as long as possible.

To change the priority level for a particular port, use the lanpower priority command. Since the switch

allows you to set priority levels on a port-by-port basis, be sure to specify slot/port information in the

command line. For example, the syntax

-> lanpower 1/1 priority critical

changes the priority value of port 1 to the highest priority level of critical. Now that the default value has

been reconfigured, this port should be reserved for those PDs that are mission critical for network

operations.
