Make a vlan up with only a trunk port assigned

[erasedhammer]

I'm trying to get a 2960g IOS 15.0 to bring up its management vlan without an interface specifically assigned to it. The uplink trunk has the vlan listed as allowed but the vlan interface itself won't come up.
All the physical ports are assigned to different vlans and shouldn't have the management vlan on them, so how I do get this vlan interface without assigned a physical interface?

!
interface GigabitEthernet0/8
description TRUNK-UPLINK
switchport trunk allowed vlan 110,111
switchport mode trunk
switchport nonegotiate
no cdp enable
!
interface Vlan111
description MGMT
ip address 192.168.11.2 255.255.255.252

can you post- show VLAN  and show spanninig  ( make sure vlan 111 110 created)

or

config t

!

VLAN 111

!

end

test and advice.

Ah! that seems to be the problem. Are vlans not created when I run int vlan XX initially?

Sure you need to create a VLAN then the  SVI comes up automatically - add VLAN 111 - test and advise.

How do I manually add the vlan to the database on ios 15.0?

Hope Device in VTP Transparent,

below command not working?

config t

!

VLAN 111
