Is cisco 2950 or 3548xl switch a layer 3 switch?

It confues me at the moment whether cisco 2950 switch or 3548xl is a layer 3 switch. (Do they have routing function?)

I can put the following commands into 3548xl switch:

int vlan 1

ip address

no shut

int vlan 10

ip address

no shut

When I do the "show int vlan 10", it says it is administratively shut down.

but int vlan 1 is up. so after I shut down int vlan 1, then do 'no shutdown' in interface vlan 10, int vlan 10 is up. But when I go back to do 'no shutdown' in int vlan 1, it says the interface is up, but the protocol is down when I do 'show int vlan 1'.

Also I cannot input the following commands into the 3548xl switches.

vtp mode server

vlan database

But accordin to cisco documentation, I should be able to do the above commands without problems.

Is it a IOS version problem? or maybe my 3548xl donot have enough RAM ? or maybe my understanding is wrong? (I think that 3548 and 2950 can do the vlan routing by themselves, like cisco 4000 ? )So do I need an external router to do the vlan routing for 3548xl or 2950 switches? but if that is the case, why can I input those commands in?)

Thanks very much for your reply.

Re: Is cisco 2950 or 3548xl switch a layer 3 switch?

Neither the 2950 series nor the 3500XL series of switches can perform

routing. (The 3550 series, on the other hand, can route.)

Both the 2950 and the 3500XL series can have only *one* interface

with an IP address active at a time. This is for switch management.

The "vlan database" is a separate command mode, *not* used within

normal configure mode. 3500XL will not accept "vtp mode server", instead

you have to use "vtp server" within "vlan database" command mode.
