Menu: Configuring VLAN Parameters
In the factory default state, support is enabled for up to eight VLANs. (You can
change the switch VLAN configuration to support up to 30 VLANs.) Also, all
ports on the switch belong to the default VLAN (DEFAULT_VLAN) and are in
the same broadcast/multicast domain. (The default VLAN is also the default
primary VLAN—see “Which VLAN Is Primary?” on page 14-7.) In addition to
the default VLAN, you can configure up to 29 other static VLANs by changing
the “Maximum VLANs” parameter, adding new VLAN names and VIDs, and
then assigning one or more ports to each VLAN. (The switch accepts a
maximum of 30 VLANs, including the default VLAN and any dynamic VLANs
the switch creates if you enable GVRP—page 14-30.) Note that each port can
be assigned to multiple VLANs by using VLAN tagging. (See “VLAN Tagging
Information” on page 14-23.)
