PropertyDescription
name ()Name of an interface
poe-out (auto-on | forced-on | off; Default: auto-on)Specifies PoE-Out state
  • auto-on - the board will attempt to detect if power can be applied to the port. For powering there should be resistance in the range from 3kΩ to 26.5kΩ
  • forced-on - detection range is removed. As a result power over Ethernet will be always on
  • off - all detection and power is turned off for this port
poe-priority (integer:0..99 | any; Default: 10)poe-priority specifies the importance of PoE-Out ports, in cases when a total PoE-Out limit is reached, interface with the lowest port priority will be powered off first.

Highest priority is 0, the lowest priority is 99. If there are 2 or more ports with the same priority then port with the smallest port number will have a higher priority. For example, if ether2 and ether3 have the same priority and over-current is detected then PoE-Out on ether3 will be turned off.

Every 6 seconds ports will be checked for a possibility to provide PoE-Out if it was turned off due to port priority.
poe-voltage (auto | low | high; Default: auto)

A feature that allows us to manually switch between two voltage outputs on PoE-Out ports. It will take effect only on PSE with switchable voltage modes (CRS112-8P-4S-IN, CRS328-24P-4S+RM, netPower 16P, CRS354-48P-4S+2Q+RM).

poe-lldp-enabled ( yes / no; Default: no)

Link Layer Discovery Protocol (LLDP) is a layer-2 Ethernet protocol for managing devices. LLDP allows an exchange of information between a PSE and a PD. 

Starting from RouterOS version 7.15, the setting has been replaced with the Neighbor Discovery lldp-poe-power property.


Info

Note: Enabling poe-lldp in RouterOS 7.8 can potentially solve issues encountered in VoIP setups.

...

Info

Note: If poe-voltage=auto and poe-out is set to "forced-on", LOW voltage will be used by default. If the PD supports only high voltage, make sure you also set poe-voltage=high when forcing the PoE output.

 

Power-cycle settings

RouterOS provides a possibility to monitor PD using a ping, and power-cycle a PoE-Out port when the host does not respond. power-cycle-ping feature can be enabled under /interface ethernet poe menu.
