We have (2) core switches which are 4503-E devices runnign in VTP transparent mode. We are finding a large amount of VLANs on the switch coming though many interfaces (some from the same interfaces of course) and have no real history or documentation to help us put them in context. The only way I know to track down where and for what purpose each VLAN was intended is to hop to each switch and compare the vlan interfaces with the trunk ports (and do the subtraction) until I find the end of the chain and hopefully see a server ir access point or something that makes sense as to why this vlan exists. Just like finding the location of a particular mac address. Is there another method? Is there a way to determine which VLAN's are getting hits or which way the traffic is coming from? Thanks so much folks!
