Make sure that speed and duplex are set to auto.

Also, make sure you have spanning-tree portfast set on each port.

I have these switches in multiple locations that all have Macs and have never had a problem with the Macs.

thanks alot your reply!

Could you tell me set the speed and duplex to auto that is in PowerMAC or in switch? and How set?

Thank you very much!

interface FastEthernet0/xx (xx=port number)

duplex auto

speed auto

spanning-tree portfast

i got it! i will test it later , however, thanks your help!

i had test, but i can set the Duplex and speed to auto in same time, prompt"Duplex can no be set until speed is set to non-auto value".

Oh yeah, I forgot. When you set the speed to auto, it automatically sets the duplex to auto.

Hi,

i faced a similar problem when i tried connecting the MAC machines, but it didn't connect. then later i went to the interface

interface fastethernet 0/24

duplex full

speed 100

u need to set this manually when u face this kind of problem, it really workede out for me. since the MAC does have the feature of setting up the speed manually u need to set this in switch port side.
