bit[7:4] --- the flooding port_no of Port1
bit[3:0] --- the flooding port_no of Port0
*ex1: bit[7:4] = “0011”b, means that if the incomin
packet of Port1 got the “un_routed” result, then
this incoming packet will be flooded to Port3.
*ex2: bit[3:0] = “0111”b, means that if the incomin
packet of Port0 got the “un_routed” result, then
this incoming packet will be flooded to Port7.
(note: set value “4’hf”, means flooding to all the
other ports; set value “4’h8”~“4’he” is forbidden)
bit[7:4] --- the flooding port_no of Port3
bit[3:0] --- the flooding port_no of Port2
(note: set value “4’hf”, means flooding to all the
other ports; set value “4’h8”~“4’he” is forbidden)
bit[7:4] --- reserved
bit[3:0] --- the flooding port_no of Port4
(note: value setting “f”, means flooding to all the
other ports; value setting “8” ~ “e” is forbidden)

3.10 Port Based VLAN
The MTD505 supports VLAN configuration by port based methodology. One port select the certain
ports to form its VLAN group by configuring the VLAN register. The packet (including broadcast packet)
is not forwarding to the destination port whose VLAN group is different from the source port.
