How to Get PoE Info From AP

Is there a way to see PoE info from an AP (GUI or CLI)? I'd like to see the actual current, voltage and power info.

Would also like to see if there are any issues with PoE. For example, an AP370 or AP390 using 80MHz channels requires 802.3at but the switch only provides 802.3af...how would I see problems with this from the AP perspective?

Jade,

We can't determine the loss from the cabling (it varies with length and type), so to check the actual power consumption you need to go to the POE switch. The closes you can get is probably to check the LLDP output for what we are currently requesting from the PSE.

You can see the power level that we are requesting from the "show lldp" command (which is also available from within Hivemanager on the monitor page under the "Utilities" button):
11ac-test-1#show lldp
LLDP general information
----------------------------
Enabled: yes
Number of LLDP neighbors: 1
Max number of LLDP neighbors: 64
Sending LLDP packets interval (seconds): 30
Sending a holdtime value (seconds): 90
Sending a required power value (watt): 15.4
11ac-test-1#

The AP370/390 will automatically determine whether the PSE supports 802.3af or 802.3at, and adjust it's power consumption accordingly.

Are the AP's able to request power through LLDP parameters? I'm specifically looking for anything related to 802.3at.

Another switch manufacture I'm working with doesn't seem to be following PoE standards. Referencing Wikipedia:

http://en.wikipedia.org/wiki/Power_ov...

To me, PoE is an L1 feature and L2 configuration should be optional. According to Wikipedia, layer 2 PoE configuration is optional. The switching vendor I'm working with seems to require LLDP based on case notes for a bug I found on their support portal (That I can't share publicly).
