For example, port 1, 2, 3 and 4 belong to static VLAN 100, and port 4, 5, 6, 7 belong to static
VLAN 120. You configure a protocol based VLAN A with priority 3 for ARP traffic received
on port 1, 2 and 3. You also have a protocol based VLAN B with priority 2 for Apple Talk
traffic received on port 6 and 7. All upstream ARP traffic from port 1, 2 and 3 will be grouped
together, and all upstream Apple Talk traffic from port 6 and 7 will be in another group and
have higher priority than ARP traffic, when they go through the uplink port to a backbone
switch C.
