MS510TXUP - POE doest not provide what is needed by Internet Access Point (Aruba 555)

Question

Not sure if it is the same, but I have a MS510TXUP with Power Over Ethernet.

I am using an Aruba AP-555.

It needs approx 38watts to fully operate. However, when I look at the power consumption it only used 13watt, resulting in a situation where the AP is not working properly, basically in restricted mode, which is a result of not enough power.

It has maybe to do with LLDP.

I hope someone can help me out? Thank you.

Where I have the following settings:

LLDP Configuraton:

TLV Advertise Interval 30 secs

Hold Multiplier 4

Reinitiallizing Delay 2

Transmit Delay 60

LLDP Med Properties: 10

LLDP Portsettings:

for relevant port:

Admin status: TX and RX,

Management IP Address: Auto advertise,

LLDP-Medd Port Setting:

Hi&nbsp;hdewitt001&nbsp;
I'm looking into it to see how to find out possible root cause.&nbsp;

Hi&nbsp;hdewitt001&nbsp;
&nbsp;
From the Aruba is see the following information:
LLDP Power                  : Successfully negotiated at 40.0W
Current Operational State   : No restrictions (Overridden by LLDP)
Eth0 HW POE status          : POE BT, LLDP power: 40.0W
Eth1 HW POE status          : NONE, LLDP power: 0.0W
The Aruba AP has done LLDP communication with MS510TXUP and successfully negotiated at 40W.&nbsp;MS510TXUP cannot push 40W into AP forcedly. The AP pulls the power from PoE switch based on the AP's actual power consumption.
1, Could you ask Aruba why the AP only consumes around 13W when LLDP result is show as abvoe?
&nbsp;
2, Could you ask Aruba how the AP can consumes more power and even to 40W?&nbsp;
&nbsp;
3, Turnning on radios is not equivalent maximum load. Could you add maximum load to all radio bands at the same time to see whether AP's power consumption gets increased (ex: testing it with iPerf on multiple PCs) ?
&nbsp;
&nbsp;
&nbsp;

Reads like a specific LLDP interoperability issue - Netger engineering is requested here.&nbsp;YeZ&nbsp;please.

Hi Sir,&nbsp;Few questions need your help to double confirm:Q1) Could we get the lldp med packets between Aruba AP-555 and MS510TXUP? it will be clear for us to confirm the negotiation between them.Q2) when issue happen, what's the power supply status on MS510TXUP? could we get a screen for it?Q3) could you provide us the firmware version, configuration file? Thanks.&nbsp;/Polly

Questions 1:&nbsp;Could we get the lldp med packets between Aruba AP-555 and MS510TXUP? it will be clear for us to confirm the negotiation between them.How do I get the&nbsp;lldp med packets between Aruba AP-555 and MS510TXUP, visible? Where do I need to look for?&nbsp;&nbsp;From the Aruba is see the following information:LLDP Power                  : Successfully negotiated at 40.0W
Current Operational State   : No restrictions (Overridden by LLDP)
Eth0 HW POE status          : POE BT, LLDP power: 40.0W
Eth1 HW POE status          : NONE, LLDP power: 0.0WSo it look like that there is a proper negotiation between the Aruba IAP 555 and the Netgear Switch POE. I see this information for both IAP's.&nbsp;Question 2: &nbsp;when issue happen, what's the power supply status on MS510TXUP? could we get a screen for it?What do you mean what with power supply status?&nbsp;As what you can see, there are Aruba IAP 555, it only pulls 11300mW and 12100mW, in other words only approx 12w, while you would expect as it was negotiated per port 40W.&nbsp;&nbsp;Question 3) could you provide us the firmware version, configuration file? Thanks.Firmware:&nbsp;Configuration file attached where sensitive info is crossed out&nbsp;XMG6 and XMG8 are the two Aruba IAP 555, which are connected, and should have 40W of power.&nbsp;
