The snooping function can be enabled/disabled individually for each of the entries. If no
entry matches, or a match occurs but snooping is disabled or the frame is coming from the
management port itself, the frame is processed normally.
29.4.5.1 Overview
The VLAN output processing function is used on a switch output port to manipulate the
VLAN tag of the outgoing frames that leave the switch. Frames are processed based on the
output Processing mode, and the number of Tags the frame contains.
29.4.5.2 Configuration Information
The switch management provides the information on operating mode to configure and
control the operation of the function using the register
are three different modes of operation, which define how the outgoing frames should be
processed.
29.4.5.3 Modes of Operation
29.4.5.3.1 Overview
The VLAN output processing function is configured to operate in one of the following
modes, which define the way outgoing frames should be treated.
29.4.5.3.2 Mode 0: disabled
No frame manipulation occurs.

Port Number Snooping is possible only if the IP header ends up
to 10 words (40 bytes) after the MAC header. If the IP header is
ending later (e.g. IPv6+VLAN or IPv4+>20byte Options) the port
numbers cannot be parsed any more and the port number snooping
will be ignored (protocol based snooping is not affected by this
limit).
For IPv6 frames the port number can only be compared if the
UDP or TCP header is the very next header to the IPv6 header
(i.e. it does not detect such headers if any extension headers are
present in an IPv6 frame before the TCP or UDP header).
