Aruba AP is not getting POE Power.

If your Aruba AP is not getting proper POE power, then we can check and consider the below point. Aruba IAP ,Aruba AP or RAP.

1.Check if LLDP is enabled On switch.

2.LLDP transit and receive both must be enabled on the switch.

3.Check if your switch has a POE budget.

4.Check if your switch has POE standards like POE, POE+, and POE++.

5.We have APs that need POE, POE+, and POE++ power from the Aruba or cisco switch.

6.Check if you have a proper Ethernet cable and a working Ethernet cable.

7.If the AP supports POE+ and POE++ power, then select a Cat6, Cat6E, or above Ethernet cable.

8.Check output  show ap debug lldp neighbour interface eth0 detail.

Aruba AP is not getting POE Power.

as you can see in the middle output.
9.It is showing 2 pairs in Category 5 UTP, full duplex mode. it means AP is negotiating 100MB link Speed.
10.This output must show as 4 pairs in Category 5 UTP, full duplex mode.  it means AP is negotiating 1000MB link Speed.

You can check interface or switch Port supported speed i.e. 1Gig or 100Mb

It means my AP is negotiating only 100 MB Ethernet speed.

11.Make sure the Ethernet cable is connected to the correct port on the Aruba AP or Aruba IAP i.e., Eth0 or Eth1.

12.Check that the switch port is working properly.

13.Connect the AP to another working switch port.

14.Check the AP’s Ethernet port and make sure it is working properly (bond0, eth0 and eth1)

15.You must check the output on the switch side as well, and it may change depending on the vendor, like Aruba, Cisco, Arista, Extreme, and Juniper.

you can use below commands for more troubleshooting:

show ap debug lldp neighbor

show ap debug lldp neighbor interface eth0 detail

show ap debug lldp counters

show ap debug lldp state
