MAS 3500 poe disabled, port still has power

[Yann]

Hello everyone,

I ran into an issue today and I was hoping some of the veterans would be able to shed light on it.

I'm in the process of installing some IAP-225s, they are all plugged in (dual homed) but the ports are in shutdown since you need to do things in order so I can configure the virutal controller. 

I'm trying to reboot a few APs via POE cycling but the port still provides power...

These are the 2 ports of an IAP-225, and I'm a little confused as to why POE is diabled but the port still provides power.

Any thoughts?

(IAP-225, Version 6.4.2.6-4.1.1.8_50989)

There was related known issue.  Will get back after checking if it is the same as that.

And also if any fix was made available in any of the higher version images.

Thanks,

[vkammar]

is 'poe-factory-initial' is applied on interfaces. and PoE is disabled under that ?

Can you try creating your own user defined poe-profile with PoE disabled, And apply that profile to target interfaces ?

[Yann]

No the poe profile isn't poe-factory-initial, I created a new profile for which poe is disabled.

[vkammar]

Can you provide below details:

show interface-config gigabitethernet 0/0/31 | include PoE

show poe interface gigabitethernet 0/0/31

show interface-profile poe-profile  <profile-name>

[Yann]

#show interface-config gigabitethernet 0/0/31 | include PoE
Interface PoE Profile disable gigabitethernet0/0/31

 #show poe interface gigabitethernet 0/0/31

Yann,

Config looks fine. Hence, there should not be issue. open a support ticket along with 'tar logs tech-support' for further investgation.

Hello Yann,

Did you find a solution for this problem? I'm experiencing the exact situation. Appreciate it you could share some information.

[VincentArriola]

I am experiencing this exact problem on a single S2500. I disabled the PoE profile and pushed it out to all of the switches through airwave and this single switch refuses to power off the IAP even though the interface and poe profile both say that it is off.

Rebooted and power cycled the switch in person, but that didn't help either.

Hi Vincent,

I had the same issue with MAS running with 7.3 firmware. This seem to be caused by a bug and had been fixed on 7.4 firmware.
