Notes
TX1
Untagged
01:00:00:00:00:01 TX2
Goes to ports TX1-TX8, but TX1 can only
send to TX2 (VLAN 4)
TX3
Untagged
01:00:00:00:00:02 TX6, TX8
Goes to ports TX2, TX6-TX8 (VLAN 3) but
filter keeps it on ports TX6 and TX8 only
TX2
Untagged
01:00:00:00:00:01 TX1,TX3-TX8
Goes to ports TX1-TX8, but won’t go back
out the port it came in on
TX2
Untagged
01:00:00:00:00:02 TX1,TX3-TX8
Goes to ports TX1,TX3-TX8
TX3
Untagged
01:00:00:00:00:01 TX2, TX4-TX8
Goes to ports TX2, TX4-TX8
TX6
Untagged
01:00:00:00:00:02 TX8
Goes to port TX8
TX3
Untagged
01:00:00:00:00:02 TX6, TX8
Goes to ports TX6 and TX8
Note: If there are multiple ports on different VLANs, the 7012FX2 will apply the static multicast address to
the lowest VLAN-ID that is associated with one of the ports assigned to the static multicast address. If the
lowest VLAN-ID contains all the ports assigned to the static multicast address (an umbrella VLAN), it will
function for all those ports with no problems. This can be achieved with overlapping VLANs.
For further information and examples on overlapping vlans, see:
