Where is VTP config info stored?

[Samuel8rown]

I notice that many vlan & vtp configuration commands don't appear in the config file for integrated IOS. What's a quick way to see and back up the current vlan & vtp configuration information? Ideally, what I'd like is something like the config file that I can save to restore if my core switch/VTP server melts.

Hi

Vlan information is stored in a file called vlan.dat which is located in flash. You can copy it to a tftp server for backup.

To view the vlans -

"sh vlan"

to view VTP info

"sh vtp status"

Turns out on my system (6509 w/ Sup720) that vlan.dat showed up in const_nvram:, but otherwise, spot on.

Thanks, man.
