power inline (interface)

To set the configure interface specific PoE settings, use the power inline command in Interface Configuration Mode.

power inline

power inline { { | auto | | | maxpairs | { < | two | | | four | > } | | | never | | | priority | { < | critical | | | high | | | low | > } | } } { }

Parameters

Parameter	Type	Description
`auto`		Enable and apply Power Over Ethernet if the device requires power.
`maxpairs`		Use this command to specify if PoE power is to provided on up to two or four pairs of wires. It is followed by the value two or four. IEEE 802.3af (up to 15.4 Watts) and IEEE 802.3at (up to 30 Watts) use two pairs of wires to supply PoE power. IEEE 802.3bt can uses four pairs to supply up to 60W of PoE power, however to ensure power consumption limits the adjacent port (odd/even combination) needs to be disabled before this can be set.
`never`		Disables PoE on the port and disables power to the port.
`priority`		Priority related configuration. The PoE port priority may be set as critical, high or low. The priority and port numbering are used to determine which ports are shut down in the event that there is not sufficient power for all PoE ports. The ports are grouped by their priority levels where critical is the last group to get shut down and low would be the first to lose power. Within those groupings preference is determined by port numbering. Example: Port 24 - critical would be shut down after Port 1 - low, but before Port 23 - critical.
