Dear all,

I have a strange problem. i've got a pc connected to a alcatel ip phone, which is connected to a cisco 3560. if i remove the pc. and connect an other one, the switch still sees the mac of the first pc. how do I change the setting that the switch will remove the mac entry?

regards,

Gerard

Turn on the following debugs to determine if the PC is sending EAP packets.

Dear Wong,

just recieved a phone call from our alcatel profider, they have changed some settings in the telephone central. now it releases the mac address within seconds. so it seems it has been solved.

thanks anyways.

Regards,

Gerard
