i have created Vlans on my switch and are active and can be seen when you do a show vlan command however when i do a show interface vlan X (where X is a vlan id ).the vlan interfaces are down.what could be the problem.Please note that vlan 1 is up.
What switch are you using ? If you take switches like 2950 , they donot perform layer 3 functions and allow VLAN for managaement purposes. Any other Layer3 VLAN u create is in shut state. Layer 3 Switches (3550 and 3560) allow u to create multiple VLAN between which u can do routing.
Sounds you are running hybrid mode. If so be aware that your interface vlan comes up as soon as you have clients connected and up. The exception is the vlan where your sc0 interface is assigned (which is most likely vlan 1).
