configure inline-power disconnect-precedence
configure inline-power disconnect-precedence [deny-port | lowest-priority]
Description
Configures the disconnect precedence priority for the modular switch when a new PD is detected and
the measured inline power for that slot is within 19 W or the slot’s PoE power budget.
Syntax Description
Default
Deny-port.
Usage Guidelines
You configure this parameter for the entire modular switch; you cannot configure this per slot or per
port.
If the power supplied to the PDs on a slot exceeds the power that was budgeted for that slot, the system
disconnects power to one or more ports to prevent power overload. Refer to
configure inline-power
budget slot
for information on configuring and modifying the power budgeted for each slot.
You configure the switch to either deny power to the next PD that requests power on that 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 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 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) on the
modular switch:
configure inline-power disconnect-precedence lowest-priority
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Specifies power be withdrawn from lowest-priority port(s) when next PD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.
