6500 Gig port Negotiation

I have a 6500 trunked to a 3548. When I do a show port or show port m/p, on the 6509 it indicates the auto-negotiation is not turned on, but if I issue the show port negotiation command it indicates it is turned on.

If I check the 3548 it says it is autonegotiating.

I had a friend try this at his site and he had the same results.

So which is telling the truth.

Re: 6500 Gig port Negotiation

What does the 6500 config say?

show config # all

#= board where port in question is

See if the port is trunk

show port trunk

see if port is channel

show port channel

What do you want to negotiate, trunking or channeling?

Re: 6500 Gig port Negotiation

The port is a Gig trunk. I was trying to ensure that negotiation was on which is required for flow control on the gig ports. When I first looked at it I thought the customer had turned it off. The show config # all is a good suggestion. When I go back on site I will try it.
