Hi Dan,

There are three requirements for the SVI to be up/up:

- The VLAN must exist and be active in the VLAN database.
- At least one interface should be active for the VLAN.
- That interface has to be in STP forwarding state.

The **switchport autostate exclude** command on the interface can be used to exclude interfaces from this check. The **no autostate** command on the vlan can be used to disable all checks completely. Not all IOS versions support these commands though.

Rene
