I believe that each VLAN on the 2950 (active or not) can have multiple IP addresses, by making them secondary.

As soon as I add another vlan (vlan y) vlan y will come up but vlan x will administratively go down. This process is repeated each time I add a vlan so that only one vlan is up at any one time, which is the last vlan created. Please note that I have vlan 1 shutdown and it is not used. > > Question is how do I keep all my vlans up simultaneously? You don't, at least not like that. A 2950 is a pure L2 switch, and it can have only one IP address at the same time, purely for management purposes. So as soon as you assign an IP adress to a VLAN interface (the 'int vlan xxx' command), the other one will go admin down. You create L2 VLANs with the 'vlan xxx' command.
