29.4.10.2 VLAN Domain Verification
When the L2 MAC Address Lookup was successful and identified a dedicated output port
for the frame, the output and input port can be verified to be within the correct VLAN
domain if VLAN verification is enabled for the port (register VLAN_VERIFY) and the
frame contains a VLAN tag. The VLAN resolution table (see 5.10.3.2 page 41 below) is
used as follows:
Freescale Semiconductor, Inc.
• If the frame's VLAN id is found within the table but the output port number is not a
• If the frame's VLAN id is found within the table and the output port and input port are
• If the frame's VLAN id is not found in the VLAN table, or the frame has no VLAN
member of the VLAN domain, or the input port is not a member of the VLAN domain,
the frame will be marked invalid and will be discarded eventually.
both members of the VLAN domain the frame will be forwarded normally.
tag, the frame will be forwarded normally (default broadcast domain), or, if the discard
bit for the port is set (also in register VLAN_VERIFY) it will be discarded.
