The switch absolutely has to be configured so that the port where
Linux is connected is a member of all relevant VLANs if the Linux
VLAN support is to be involved.

Depending on the addressing plan that could get really messy really
quickly, especially if the application has no knowledge about the
network and lots of translation is required.


I would prefer many VLAN interfaces in the Linux system. Linux can
have all 4095, but the /proc/net/vlan interface has a static memory
limit in the driver which should be increased if you want access to
information for all interfaces.
