There are limitations when configuring multiple VLANs on a port and when
configuring VLANs that cross multiple switches. For example, to have multiple
VLANs that span multiple switches, no port should be configured to exist in more
than one VLAN in any of the switches. This method partitions the switches into
different, non-overlapping VLANs as shown previously in Figure 1-7
.
It is also possible to have resources exist in multiple VLANs on one switch as
shown in Figure 1-8
. In this example, clients on different broadcast domains share
resources. The broadcasts from ports configured in VLAN V1+V2 can be seen by
both VLAN V1 and VLAN V2 ports. Broadcasts from VLAN V1 ports can only
be seen by other VLAN V1 ports or VLAN V1+V2 ports. This analogy is also
true for ports that are assigned to VLAN V2.
