Hello,

After some search I found something
In fact only one port is consuming enery (Gi2/0/7) in this stack of 2 N2048P
So I tried to understand why it is known as 61
After many snmpwalk I found the solution.
If you look at the ending index, you will see when it reach 48, it jumps to 55
So we have 1st switch from 1 to 48 and 2nd switch from 55 to 102, 48 ports each time
With this, interface Gi2/0/7 is corresponding to 61 so si the answer.
But a gap is remaining. The only reason I see is because of additionnal card.
In fact you can add a 4 ports 1G card or a 2 ports 10G card.
This meens ifIndex for theses ports should be reserved by a total of 6 (4 + 2) from 49 to 54
Do you think I should "power inline never" the interfaces not consuming power to solve the problem ?

Cordialement,

So I used this site to find the oid :
http://cric.grenoble.cnrs.fr/Administrateurs/Outils/MIBS/?module=POWER-ETHERNET-MIB&fournisseur=DELL

and you can see the result in joined file after a snmpwalk

Well, it appears the switch is only reporting the power classification
of a single port, identified as 1.61 (group 1, index 61).

I'm not too familiar with the MIB, but there seems to be no definite way
of mapping ths port index to an ifIndex, as used by other MIBs, but on
most vendors, the port index seems to coincide with the ifIndex (except
on Cisco, where we need to get a mapping from a proprietary MIB). Not
sure how Dell switches treat this.

Does your switch have an interface with ifIndex 61, and is there
something unique about this interface?
