HPE Switch Does Not Provide 45W To The CLASS 6 AP Device
The switch does not provide 45W to the AP which in this case is a CLASS 6 device. The switch in question is a 2930M which does support CLASS 6 PoE devices.
Switch – Aruba-2930M-40G-8SR-PoE-Class6 (R0M67A)
AP – Aruba AP 303
Somehow the AP shows itself as a class 4 device in the pcap in the LLDP information.
The AP announces itself being a class 4 device in the LLDP information that it sends to the switch.
Quite obviously, this leads to suspect that the issue is with the AP.
However, turns out that there are things that need to be taken care on the switch end as well.
1) Upgrade the software to 16.09
Once upgraded you will see a line in the config that pops up on its own:
untagged vlan 1
lldp admin-status disable
The line highlighted in yellow will show up on its own once the software is upgraded.
Change it by running the following command:
lldp admin-status 7 tx_rx [this command will change the LLDP status for port 7 alone]
lldp admin-status eth all tx_rx [this command changes the LLDP status for all ports on the switch to enabled mode]
2) Make sure to change the PoE allocation by class
The config should look something like:
untagged vlan 1
The switch should understand by negotiating with the AP that it is a CLASS 6 device. You might then need to configure the AP for PoE and other port options.
Finally the power on the port should look something like:
Aruba-2930M-40G-8SR-PoE-Class6(config)# show power brief eth 7
