Hi,
on a 4500 I am currently trying to get the information how much power a connected poe ip phone uses.
I got the following command output:
show power inline gi1/1
Interface Admin Oper Power(Watts) Device Class
From PS To Device
--------- ------ ---------- ---------- ---------- ------------------- -----
Gi1/1 auto on 7.5 7.0 Ieee PD 2
Interface AdminPowerMax AdminConsumption
(Watts) (Watts)
---------- --------------- --------------------
Gi1/1 20.0 15.4
===================
show power inline police gi1/1
Interface Admin Oper Admin Oper Cutoff Oper
State State Police Police Power Power
--------- ------ ---------- ---------- ---------- ------ -----
Gi1/1 auto on none n/a n/a 3.2
It would be fine if somebody could explain exactly the following terms:
- Power from PS
- Power to Device -> amount of power the phone uses?
- Operational Power -> also the amount of power the phone uses?
- Admin Power Max
- Admin Power Consumption
Best Regards,

Your phone is pulling 15.4 watts of power but the port is allowing up to 20.0 watts.

That's not what I think.
In my eyes it pulls 3.2 watts which is the operational power shown in the second output. Further it's a class 2 device which afaik pulls not more than 6,49 watts.
