More than one VLAN on a Switch

Unanswered Question
Mar 23rd, 2007

I need to have more than one VLAN UP on a Switch 2950. At present, it has VLAN 10 which is up with a device in it. When I create another VLAN12 and put 2 other ports in it, that?s ok but when I do show vlan12 it shows administratively down and will not allow me ping the gateway.

Please help.


I have this problem too.

That address is to manage the switch only and has nothing to do with using the address as a gateway for attached clients , all your routing is done on a layer 3 device , a 2950 is layer 2 only so it only needs one address to to manage it . You can create as many layer 2 vlans as you want but you would have to trunk the uplink to a layer 3 capable device to route between vlans .

All you need to do is, create the vlans, under interface vlan x, do "no shut", assign vlans to ports/hosts, and trunk the link towards gateway. You can create only a single SVI(vlan wth ip add) on 2950, but reachability would be for all vlans passing thru trunk.
