Catalyst 2100 and duplex

When i setup the 100 mbit port to full duplex, it cant agree with the other side, the speed is about 1 mbit

but if i make it to half duplex it is faster , i has tried to connect it to many switches and Nic´s but it is all the same

Are you sure the other end of the connection supports 100mbps ? Do the NICs you use support autonegotiation ?

I don't really know if I understood your question correctly

hey , yes , all nics and switches are 100 mbit
and they support autonegotiation , but they cant be friends with that
i need to set it to 100 mbit half duplex
and i dont want to have half duplex

well i guess you gat no other choice that to have the half duplex done.
