29.4.10.3.3 VLAN Switching and Resolution Mechanism
The VLAN table is used for both, VLAN domain verification (see section
Verification) as well as VLAN resolution. Once the frame has passed any VLAN domain
verification (that is, will not be discarded by the verification function already) the forwarding
resolution applies.
To disable the VLAN resolution, set all VLAN IDs to 0xFFF or (0x000 if that id is not
used) and all Port Mask bits to '1'. If the VLAN resolution is disabled, normal port flooding
is implemented as described in section
be used to restrict broadcast to only dedicated ports, if not programmed to all '1'.
