Hi qauravm,
When you say your vlan is down do you mean your interface vlan
The only reason can be nothing connected to that vlan on that switch, You need to have atleats one network device connected to that vlan on any port to bring it up or also if you have any trunk port configured on that switch and if that trunk allows that vlan then it will be up.
Also check if that particular vlan is present in vlan database.

hi,
i have created 2 vlans (VLAN @ and VLAN3)in my L3 Switch .
one of port is configured for vlan 2 (connected to switch 2).
i want to pass on the vlan 3 info also on to the other users on switch2.
interface GigabitEthernet3/5
switchport access vlan 6
switchport trunk allowed vlan 6,7
but it says Vlan7 is up, line protocol is down.
kindly help...

Hi Qaurvm,
You have created 2 vlans . Vlan 2 and Vlan 3 but you are allowing vlan 6 and 7 on trunk. Have you created vlan 6 and vlan 7 in your vlan database.
Can you paste your "sh vlan" information.

Hi Quaravm,
Here you go with the answer and the solution...
You have just created the vlans but for vlan to be active some ports need to be assigned to that vlan or either there should be a trunk and that vlan should be allowed.
I am sure currently you do not have any ports assigned to vlan 7 and because you have connected the 2 switches with vlan 6 on it that is the reason vlan 6 is up.
First create the trunk between the 2 switches and once trunk is up vlan 7 will also be up and later you can restrict only vlan 6 and vlan 7 on the trunk.
Make sure you craete the trunk first.
