We are migrating from Lucent QIP to MetaIP for DHCP services and so far we have had two issues when MetaIP has been implemented for VLAN that has an unauthorized Linksys router giving out IP addresses. Is there a scanning tool out there that can determine if there are unauthorized Linksys (type) routers in a specific VLAN?
Try pinging all hosts using nmap: # nmap -sP 192.168.1.0/24 Then look at the arp cache: # arp | grep ether Then find MAC addresses that are from Linksys's space. I know macchanger [1] has a list of what addresses belong to which vendors. Hope this helps. [1] http://www.alobbs.com/modules.php?op=modload&name=macc&file=index -- gram
