If I remember correctly the 1950 can only have one IP interface, and when you activate the second one it disables the first one. The 2950 is not really a router so you can only have one ip address on it.
The 2950 is a layer 2 switch and only supports a single SVI (ip address on a vlan interface) for mgmt. purposes. Vlans can be created, but you need to trunk to a router and provision subinterfaces on the router for inter-vlan routing to occur. Hope this helps.
First of all , you cann't give two IP addresses on two different VLANs at a time in any Layer2 switch. If you do so, then one VLAN will be up & running but second one will go down .Cisco 2950 is a Layer 2 switch.That's why this problem is happening with you.
You are correct. You can assign multiple IP addresses (one per VLAN), but only one can be active at a time.
The IP addressing on an L2 switch (like the 2950) is just there for management (so you can telnet to it). You should also remember to put in a Default Gateway so your telnet traffic can be routed throughout the network, not just the local segment.
(also pay attention to which VLAN is your Native and Management VLAN)
