Help with 6506-E Config

I have a 6506-E with 720 Sup. I am trying to connect a server with HP 550SFP Nic to my 6506.

If I plug the SFP from my server into my 6506 it will not link. When I plug that very same SFP into a 3750 it links fine. Makes me think that there is something I am doing worng on the 6506 Config.

But, If I plug another server using a IBM LAN Card into the same port on my 6506 it connects and works fine so now I am starting to wonder.

Any toughts or suggestions would be helpful.

Help with 6506-E Config

Defaulted the config on interface



switchport host

switchport nonegotiate

Tested connections and I am still at the same point.

Any other thoughts?

I think that interface is configured for non negotiate, so its better to change it to

Switchport mode access

Switchport access vlan 1

no shut

Thanks for the input

I finally figured out today that I had to set the following to get it to work.

speed nonegotiate

speed 1000

Once I did this they started linking correctly.
