The services of different virtual bridges are isolated and the services with different VLAN
IDs in the same virtual bridge are also isolated. The switching domain of the entire virtual
bridge is divided into multiple sub-switching domains according to the VLAN IDs.
As shown in Figure 4-17, the same logical port may belong to one or more sub-switching domains with
different VLAN IDs. On the U2000, the same logical port can belong to multiple filtering tables with
different VLAN IDs.
