DGS-6604 m poe port priority 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 Syntax Description {1st | 2nd | 3rd} The 1st, 2nd and 3rd port priority. The lower number has the higher priority Default Command Mode Usage Guideline Example The default priority for all of ports is the lowest one (3rd). Interface configuration 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. This example shows how to configure PoE port priority at port eth3.1 with the first priority.
