IE-4000: Unable to set speed to 100 Mb/s between 2 Switches

[mdrm]

Hello,

I'm not able to set the speed between 2 IE-4000 Switches to 100 Mb/s. If I set the speed in both ports to 100 Mb/s nothing happens. The link only functions with an speed of 1000 Mb/s.

This is my configuration:

Switch1(config)#int gi1/1
Switch1(config-if)#speed 100
Switch1(config-if)#duplex full
Switch1(config-if)#end

It only functions with "speed 1000"...

Can someone help me?
