Why does one vlan go up and the other immediately goes down (cisco 2950)?

Question

Network administration

I am studying ccna course. Reached VLANOV. I wanted to try L3 switch but I can't raise 2 vlans at once.
As soon as I do no shutdown on one, the second one immediately falls off? Are there any licenses missing?
Catalyst 2950
Moscow(config-if)#no shutdown
01:29:14: %LINK-3-UPDOWN: Interface Vlan60, changed state to up
01:29:14: %LINK-5-CHANGED: Interface Vlan50, changed state to administratively down
01:29:15: %LINEPROTO-5-UPDOWN: Line protocol on Interface Vlan60, changed state to up
01:29:15: %LINEPROTO-5-UPDOWN: Line protocol on Interface Vlan50, changed state to down

Answer 1

Because the 2950 is an L2 switch and can't have more than one L3 interface?
