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lowest-priority	Specifies power be withdrawn from lowest-priority port(s) when next PD requesting power connects.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 SummitStack; 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.

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). For information about configuring the PoE priority for the ports, see configure inline-power priority 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.

From ExtremeXOS 30.2 , in ExtremeSwitching X465 series switches, when deny port is configured when ports are given priority, priority overtakes deny port action.

Example

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

configure inline-power disconnect-precedence lowest-priority
