poe port priority
Use this command to configure the priority of power-sourcing for ports. Use the
no poe port priority command to return to the default settings.
poe port priority {1st | 2nd | 3rd}
no poe port priority
Default
The default priority for all of ports is the lowest one (3rd).
Command Mode
Interface configuration
Usage Guideline
PoE supervisor system will calculate the available power which is called the
power budget when system initializes. Once the system is running out of power
budget, cannot provide enough power to the connected PDs. Supervisor system
will reallocate the power for all active PoE ports. The port with higher priority will
get power first. Then there is a possibility - low priority port power could be cut off
because of a new higher priority port is connected with a PD and power budget is
limited.
The relinquishment of PoE port power can cross unit by the management of PoE
supervisor system that means if there are multiple ports have been assigned with
same priority, then these ports will be powered off when system power is going to
be insufficient after inserting a PD at higher priority port. In the condition of
multiple ports with the same priority, the port ID with less number take
precedence.
Example
This example shows how to configure PoE port priority at port eth3.1 with the first
priority.
