Aruba model 320 ap's cannot draw enough POE from SSA

Aruba AP model 320 goes into low power setting when connected to POE on SSA. I set the inlinepower port capability to 8023at for 34w but I see no difference in the usage number. This is happening with several aps. on different ports.

SEC_Core_SSA(rw)->show port inlinepower ge.1.15

Port Type Oper Admin Priority Class Power Power PD

ge.1.15 delivering power auto low 4 34000 6000 8023
8023at 8023at


Is there another setting I could use to force the port to more power?

thnks in advance

There are 2 commands you need to do to give your access point the ability to use "at" power.
Looks like you did the first but probably didn't realize you needed the second:

set port inline ge.1.15 type "power hungry AP" powerlimit 34000 capability 8023at
set lldp port tx-tlv poe ge.1.15

Power is negotiated via lldp at a low level and by default is not enabled on S-series
as well as K-series by default. I have been told that it is OK to enable it on all ports.

"power hungry AP" is just a descriptive string, like the ifAlias. A few (not many) phones require the extra power as well as some (not all) PTZ cameras (Pan Tilt Zoom cameras).

Hope that helps!

Hi Walt,

Each of the following are necessary:

*Upgrade the S-series to 8.42.04.x – released August 2016

As of 8.41 f/w the mdi tlv's and most 802.11ac grade AP interop functional. 8.42 code has some tuning to clear all known interop problems.

*Set lldp port tx-tlv poe ge.1.15 Allows L1 criteria communication

*Set lldp port tx-tlv med-poe ge.1.15 Allows power value negotiation - the most recent fixes (*8.42.etc) have been in this area.

In line with the suggestions added up to this point - but additional code level and command required.

That should work.
