I wanna know what features of cisco 3750 for detecting duplicate ip addresses.let's say I assign 5 IP addresses for my managers by using the dhcp server.If someone(internal users) try to set those ip addresses manually then how do I (prevent/detect) duplicate ip addresses in this case.

What are features of cisco 3750 can do?

please feel free to add any comments


Thanks

I think the DHCP server will check that an IP address is not in use (by ARPing for it) before it issues it.


Conversely, a statically configured PC will also do an ARP for its own address before it boots up, and if it detects a conflict it will tell the user and not boot. I cannot say what other types of host might do.


If you really want to tie it down, you could make a fixed DHCP mapping, but this can get administratively heavy on a big site.
