How does the VTP database get saved on a CATOS switch?

If a CATOS switch is put in text config mode where the config is not automatically saved to NVRAM but saved with the write mem command to flash then how is the VTP information saved?

If you're in TEXT MODE, it's not going to be saved unless you set the AutoSave interval.

thanks TonyPh12345,

But if I "wr mem" the vlan database and the vtp config should be safed to the startup-config?

TonyPh12345

Well, certainly the VTP config will. The VLAN configuration, which is learned from the VTP Server is NOT stored in NVRAM. It is stored in Volatile RAM. Only the SERVER stores the VLAN Database in NVRAM.

So if a switch is in vtp client mode then you do not have to worry about it overwriting other switches vlan configuration?

If you install/reinstall a switch and it is in server mode then the revision number should be reset to 0 but if the switch is in client mode then it will boot with a revision number of 0?

If a switch is in VTP client mode do you have to worry about the revision number if you return it to the network after being down or in a lab?

thanks decoleur and DevilWAH,

So if I am in text configuration mode instead of binary configuration mode then it does not affect how the vlan.dat is saved?

If the VTP mode is server then the Vlan.dat will be saved to nvram regardless of the switch configurtion mode?
