Network IP Conflict

We currently had a client that plugged in a router into their network without any authority that caused an IP Conflict and just so happened to be the sam IP as their router IE: 192.168.1.X which took out Exchange and a lot of users accessing internet etc. Is there any way to implement onto our Switches(ProCurve Switches) to disable any new IP device especially if it is a conflict.

Normally it's possible to disable or shutdown the unused ports/interfaces at the switch. But that solution is not very flexible, because if you want to connect a new network device, you have to activate this port again.

Seems it's possible.... comes under the term 'Duplicate IP'.

You will need to research 'Network Inmmunity Manager' and NBAD - Network Based Anomaly Detection Protocol...


See this HP document - http://www.hp.com/rnd/pdfs/4AA1-3566ENW.pdf

Hope this helps

You could statically assign the ARP entry for the actual router on the switch.
