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.

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".

timm.benkula · ‎03-16-2005

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.
