BTW, VaibhaV….if you span that VLAN across your network (IE…Roaming VLAN) you better understand and DOCUMENT your layer 2 network to the ninth degree because an issue in/with that VLAN will effect every switch in the network because each switch in the network has that vlan residing on it.

I also want to know about Roaming VLAN ie same vlan for whole campus is it possible Hi

I also want to know about Roaming VLAN ie same vlan for whole campus is it possible

It seems like it is the piece of the puzzle that broke the camels back. Never a fan of automatic network configuration in most cases. Not to say I do not use templates, because I do. But I've seen my share of quirks with CiscoWorks and the WLSE for that matter. Is VTP the crux of the problem or automatically letting CiscoWorks configure the switch in the first place? Now the idea that misconfiguration can occur with VTP is not lost upon me at all. But human oversight is as much to blame here as mostly anything else. Why was the switch left a VTP Server in the first place? Sounds like Lucy has some explaining to do. Funny, I would think to question the operational functionality of Ciscoworks Server.

VTP "shouldn't" be use at all cost. I rather manually configure the VLANs than let VTP destroys the network and then configure the VLAN afterward. My customer has experienced a similar situation. Their CIO seats not far from the switch closet and saw them changing the switch out before the whole network dropped. Talk about maximum exposure to your upper managements.. Yup, I totally agree.
