Thanks a lot guys,

I have to agree with Adel's solution, it came to my mind also and I tested it before.
But what bugs me is this the only viable solution?
Because there is no mention of this particular VLAN in the scenario.

Any other ideas?

BTW secure ports and protected ports are mutualy exclusive, right? Can't do L2 security then.

I would assign 10.1.1.2/30 to the vlan interface and limit that vlan only to a particular port. It will not route anything other than 10.1.1.1 from the other side in case this needs to be routed out later on. This is in addition to port-security.
