We have a Softlayer account with multiple VLANs configured in one datacenter. When launching an instance we can specify which vlan it should use for its frontend and backend interfaces, but if we don't seemingly they will be chosen randomly.
First question: - can we set the default frontend/backend VLANs for a datacenter that will be used when there is nothing provided explicitly in the request?
Second question: - can we protect a VLAN so that nobody but a specific user could provision devices in it?
