Debugs to see power negotiation

[ankugarg]

Can someone let me know the debugs which can be used to see cdp and lldp power negotiation of cisco poe switches with phones etc.I have some phones which take abt 15w with one switch,and same phone takes abt 7w with another switch.Just want to see the debugs why the power negotiation is not happening...thanks.

I can't answer that, but how about this: Troubleshooting Power over Ethernet (PoE)

There's a section called Debug and PoE.

I was looking for debug ilpower.

So I didn't answer your query? 

[ankugarg]

Well,i got only from the document you referred

[Leo Laohoo]

Ok.  There are some stuff there about "debug ilpower".

As you can see, this document is fairly outdated.  Maybe you can create a document bug and include TDR in it?

[ankugarg]

Well,documentation team will take care of only those documentation bugs which are in the config guide..Let me send a mail to Documentation team of 3k series to make one similar document for 3750 X(which has additional poe capabilites),and include tdr in it..Chances of getting to conclusion are pretty less,but lets try.

Or let me ask them if i can write one myself,if they can publish that after review.

What models are these two switches?

[ankugarg]

These are 3750 X ..This is just the test setup...Many other things can go wrong even without a wrong in switch
