I have two Catalyst 2950 series. I just deleted the vlan.dat file and reloaded both of the switches. Now, when I try to configure the VTP domain on one of the switches in CLI, I am missing the "mode" option. I've enclosed a copy of the CLI from both switches.
Looks like one has a really old code version on it and you may have to use the vlan database to configure . Check versions to see if the one is a really old version of IOS . Current versions are like 12.1.22a.ea12.
You will see the deprecated message on newer versions . Supposedly at some point cisco will drop the vlan database . Haven't used it in years anyway . Just set the switch as transparent and configure everything from the global command line . All your vlan info will show up in transparent mode in the running config. Those versions you are running are some of the oldest I have ever seen in that series .
