configure inline-power disconnect-precedence

configure inline-power disconnect-precedence [deny-port | lowest-priority]

Description

Configures the disconnect precedence priority for the switch when a new PD is detected and the measured inline power for that switch or specified slot is within 19 W of the switch‘s or slot‘s PoE power budget.

Syntax Description

deny-port Specifies power be denied to PD requesting power, regardless of priority.
lowest-priority Specifies power be withdrawn from lowest-priority port(s) when next PD requesting power connects.

Default

Deny-port.

Usage Guidelines

You configure this parameter for the switch and for the entire modular switch; you cannot configure this per slot or per port.

If the power supplied to the PDs on a switch or specified slot exceeds the power that was budgeted for that switch or specified slot, the system disconnects power to one or more ports to prevent power overload. Refer to configure inline-power budget for information on configuring and modifying the power budgeted for each switch or specified slot.

You configure the switch to either deny power to the next PD that requests power on that switch or slot, regardless of the priority, or to disconnect those PDs on ports with lower priorities until there is enough power for the new PD. If you select this last argument and you did not configure port priorities or if several ports have the same priority, the switch withdraws power (or disconnects) those ports with the highest port number (s). Refer to configure inline-power priority ports for information on configuring the PoE priority for the ports.

The default value is deny-port. So, if you do not change the default value and the switch‘s or slot‘s power is exceeded, the next PD requesting power will not be connected.

When the setting is lowest priority, the switch continues dropping ports with the lowest configured PoE port priorities, or the highest port number in the case of equal PoE port priorities, until there is enough power for the requesting PD.

Example

The following command sets the switch to withdraw power from the lowest-priority port(s):

configure inline-power disconnect-precedence lowest-priority
