Hi There,
We have 2 Cisco 2960's (WS-C2960-8TC-L) trunked together via interface Gi0/1 on each switch using SFP's (GLC-FE-100FX). Switch Version 12.2(50)SE3
Although the link is up and operational it is only running at half-duplex (a-half a-100) and we are unable to force speed or duplex changes on interface Gi0/1.
Gi0/1 .1Q TRK to SW2 connected 1 a-half a-100 100BaseFX-FE SFP
Should this configuration set-up run at a-full a-100 or do we need a different IOS image.
Thanks in advance
Jim.

Under the gigabit interfaces add this -
int gi0/1
media-type sfp
then you should be able to configure duplex/speed settings.

Jon,
That has worked now allows me to alter the duplex setting (speed cannot be altered due to to fixed rate of SFP).
Thanks for your help
Jim.
