I've tried version 0.99.2, 1.1.0pre2 and head, always the same result.

I must correct my statement referring to the vlan settings:
- trunks=501 isn't working
- tag=501 was never set, this was a setting of the physical switch

Fact is that configuring vlan trunks causes trouble im my case as described.
It works if vlans are managed by the physical switch.

Sorry for the confusion.
