Hi guys,
 
I'd like to know whether there are some mechanism to acchieve the following
issues with DHCP:
 
1. If illegal person set up another DHCP server. Clients will only select
the DHCP server who respond quickly. How to avoid the legal DHCP from being
disturbed by illegal server?
 
2. In an DHCP domain, clients can also configure themselves with static IP.
Can switches refuse those clients to work?
 
3. I've been told that DHCP could work with RADIUS to acchieve
authentication before allocating IP address. Are there any mature products
then?
 
Sorry for disturbing you all. I am looking forward to getting your help.
 
Hai,
