Wireless Access

Hello everybody,

we have an Mobility-Master managed Aruba deployment and I want to get the power consumption of an AP via ArubaAPI on the MM. Is this possible? Or are there other ways to get this data?

I could get it from our switches but i don't want to walk over every switch an ap is connected to.

Thanks for your help.

Following... and hope someone from Aruba chimes in.

I've been looking into this as well and cant find anything. I was hoping there would be an OID I could run against the controllers to return actual power consumption but I couldn't find anything.

Closest on the controller CLI I can find is the "Power Status" section of show ap debug system-status but even this doesnt display actual power consumed. Ive had to revert to the switches to get actual power usage. Probably going to have to end up writing a script to walk and poll all of the switchports for my APs to get actual power usage. Wish there was a way to poll this from the controllers.

Part of my research is two fold - one for just auditing power in general... the other is I'm playing with 802.3az and I'm having trouble confirming if the APs are actually reducing power.

unfortunately there is no way to gather all power usage of multiple APs in an easy manner. We have some minor CLI improvements in newer code with newer APs, see "show ap power-mgmt-statistics ap-name <>" but not all APs support this, nor all AOS versions.

In the ap debug system status, just below the "Power Status" output you should find the the power consumption:

Power Monitoring Information
----------------------------
Current(mW)  Average(mW)  Minimum(mW)  Maximum(mW)
-----------  -----------  -----------  -----------
5841         5730         5640         6542

Note : Avg, Min and Max power are calculated using values sampled over the previous 60 seconds

that information together with power status should give you an idea of what the AP is doing (together these are rolled up into "ap power-mgmt-statistics" on AOS versions that support it, I think 8.6 and up.

With that said, trying to use a script to continually poll many APs using "show ap debug system-status" is not recommended on a production system.

@jgoff - Thanks for this update...

Any idea which models will support the new commands? Only 5xx series? What about any 3xx series, or current hospitality models (303H & 205H)?

@censania - the "ap power-mgmt-statistics" if i recall exists on AP 345 in addition to all AP 5xx, but it won't be back-ported to older APs like 303H and 205H unfortunately.
