In my switch closets I have 2948-XL switches. Recently we've had a rash of people plugging devices into the network that act as DHCP servers. Naturally this causes all sorts of conflicts and has to be tracked down and stopped each time it occurs.
I've been unable to find a solution to this problem using my 2948-XL switches (i.e. a way to only allow dhcp responses from our actual dhcp server)... so it looks like its time for replacements. Can anyone recommend a switch that supports this feature (cisco calls it DHCP snooping I think),
48 ports+ 10/100 ports and VLAN capability (port + trunking). Bonus points if its not too pricey (obviously cost is a real issue or I wouldn't still be using 2948s).
Many thanks in advance!
