Getting R710s to use POE+ (802.3at) mode on Netgear GS752TP switch

[rohan_vanden_dr]

Hi.
I have 4 R710s connected to a Netgear GS752TP PoE switch which I cannot get to use PoE+ (802.3at) mode.

Looking at some of the previous posts and information, I SSHed into each R710 and found LLDP initially disabled, so I enabled via CLI. Now get lldp for all APs reads:

LLDP state: Enabled
LLDP interval: 30
LLDP holdtime: 120
LLDP mgmt: Enabled
LLDP bond type: Source MAC for LLDP frames on bond slaves: fixed
LLDP poe: Enabled
LLDP power: 25000
LLDP interface:
LLDP on eth0 : Enabled
LLDP on eth1 : Enabled
OK

On the GS752TP switch, all access points are connected to the first 8 ports (which are POE+ 802.3at capable). 

On the LLDP settings for the switch, I've enabled transmit optional TLVs for ports 1-8, which should include Power via MDI.

Unfortunately all APs still remain in 802.3af PoE Power Consumption Mode.

Any ideas on how to fix this ?

Thanks.

ok, and which ports on the screenshot do you have R710 connected to?

Sorry. To be clear I have R500s attached to 3, 7, 10 - which covers both power options on the switch.

The R500 is a lower power device than R710 so only needs "af". 

This was to give you a view of what is available on switch and to that R500 works off off boths kinds of POE port on default settings. If I had an R710 I'd put it on and see what happened!

Release notes for firmware 9.1.2.0.204
include...

Resolved Issues 1. Resolved an R710 PoE issue that occurred when the AP was connected to a switch that only supported 802.3af PoE mode. [ER-3225, SCG-47346]

This might be fixed but you are seeing other POE issues that are lurking in background.

for instance: from firmware release 9.12.1 December 2015

R710 Known Issues • No Syslog message is sent for 802.3af PoE mode change. [ZF-13160]

R710 AP continues to request 25W power from the PoE switch even when the AP is configured to 802.3af mode. [ZF-14489] R710 Features Not Supported in This Release ZoneDirector Version 9.12.1 Release Notes, 800-71040-001 Rev E 17

Workaround: Disable LLDP Power-Via-MDI TLV on the PoE switch (this is only necessary if you wish to force the AP into 802.3af PoE mode on an 802.3at PoE+ switch for power budgeting reasons). On some switches, you may need to reset the AP connected Ethernet port/s to force the switch to renegotiate the new power level.
