Howard, Solve rouge DHCP server issues by enabling DHCP snooping on your closet switch(es) for the VLAN(s) in question. If the kids are smart enough to NAT you need to hire them for work study students.

We have some large dorms that use multiple VLANs, and they seem to be messing with the port based VLAN on the switch between the CAS and the buildings. I have a router capable of 80 million PPS, and it's idling, but stops passing traffic intermittently on that VLAN. Driving me to distraction.

Enough so, it might call for some research on my part if no one responds... Way to make people think! :) Not sure if it's like Network connection sharing for XP, but it usually involves putting the fluke in that VLAN and looking for rouge DHCP servers...

Does anyone know of a rule we could define, or a clever way to find them? Any ideas would be welcome. ****************************** Dave Bachand Data Network Manager Eastern Connecticut State University E-mail [EMAIL PROTECTED] (860)465-5376 ******************************
