Issue in Negotiation 1 Gbps

Hi,

Facing issue in Cisco 6509 switch with the port speed and duplex servers are not negotiating on 1 Gbps but it is working on 100 Mbps.

We have tried by making combination of Auto / 1000 Full Duplex on both switch and server side but still it is not working.

Logs are attached

Rakesh,

Are all servers connecting with 100Mbps?

You did hard code on both ends. Still not working. It sounds a bit crazy but what is the media type you are using? Cat5?

Check the wiring , you need 4 good pairs all the way thru to the servers as gig uses all 8 wires to run. 1 bad wire or pair will not allow gig service.

In addition to glen check whether the server NIC drivers are upto date

Have seem some problems due to them in the past

Are you sure the server's NIC will go 1Gb???

Can you post what is the NIC's model number?
