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.
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.
Hi everyone, I would like to thank you in advance for any help you can provide a newcomer like myself!
