Static Virtual LANs (VLANs)
Port-Based Virtual LANs (Static VLANs)
showing the (different) source VLAN and source port. Other switch models
have a single-forwarding database, which means they allow only one data­
base entry of a unique MAC address, along with the source VLAN and source
port on which it is found (see Table 2-6). Not all VLANs on a switch covered
by this guide use the same MAC address (see “VLAN MAC Addresses” on page
2-39). Connecting multiple-forwarding database switch to a single-forwarding
database switch where multiple VLANs exist imposes some cabling and port
VLAN assignment restrictions. Table 2-6 illustrates the functional difference
between the two database types.
