Enable Pre-Tag on
Switch SW5-MII/RMII
Interface
1, packets forwarded to Switch MII/RMII interface will
be pre-tagged with the source port number (preamble
before MRXDV).
0, normal operation.

1
Enable “Tag” Mask
1, the last 5 digits in the VID field are used as a mask to
determine which port(s) the packet should be forwarded
to.
0, no tag masks.
Note: you need to turn off the 802.1q VLAN mode
(reg0x5, bit 7 = 0) for this bit to work
R/W
0
Sniff Mode Select
1, will do Rx AND Tx sniff (both source port and
destination port need to match).
0, will do Rx OR Tx sniff (Either source port or
destination port needs to match).
This is the mode used to implement Rx only sniff.
