2960 uplink Giga ports Slow

Unanswered Question
Nov 4th, 2008

Dear Sir's

It is the first time I used this forum, and I wish that you can help me.

I have 2 Catalyst WS-C2960-24-TC-L and WS-C2960-48-TC-L each one of them connected to other network with SPF on one of the Giga uplink ports.

now I have one empty Giga uplink port on each one, so I connect them to 2 servers ( having giga network card inside ).

tha problem is that these 2 servers becomes very slow than connecting them to normal 100 MBPS ports.

My servers network status show 1 GBPS speed, but speed very low.

Is there is some setting for these uplink ports to have a real speed Of 1 GBPS.

Thanks in advance.

Eng. Amgad Steen

I have this problem too.

If you do a show interface status on the switches what does it show for the interface speed and duplex ? Also verify patches are good , to run gig speed you have to have a good patch that has all 8 wires , gig uses all 8 wires . Normally to run gig you just leave the ports as auto and they will negotiate gig if both sides are capable.
