VTP - Client Mode

[nishantusa]

Mr. Lammle,


On Page 564, you wrote "VTP client mode.... This switch will learn about but won't save the VTP configuration in the running configuration, and it won't save it in NVRAM."

I do understand the part it won't save it in NVRAM (startup-config). But while switch is on and running, it has to save the VTP -VLAN info somewhere, right and one place it make sense to me is the running-config (RAM).

Please explain.

Thanks,
Nishant

From my cisco press book:

you can not creat, change,modify or delete vlans when in client mode.Vlan information is not saved in NVRAM

thats all it says so it must save it in running config which is ram or it wouldnt learn about the vlans.

Vlan information is stored in vlan.dat. (use sh flash)

You should be careful when plugging in a switch that it has vlan on it.
Even if you write erase, you will not clear the vlans.
To erase vlans.
switch1#delete vlan.dat
Delete filename [vlan.dat]?
Delete flash:vlan.dat? [confirm]
switch1#reload
