VLAN Environments
You can configure different VLAN types in any combination. Note that the
default VLAN will always be present. (For more on the default VLAN, refer to
“VLAN Support and the Default VLAN” on page 2-45.)

Port-Based VLANs Protocol-Based VLANs
VLAN Environment Elements
The default VLAN (port-based;
VID of “1”) Only
In the default VLAN configuration, all ports belong to VLAN
1 as untagged members.
VLAN 1 is a port-based VLAN, for IPv4 traffic.
Multiple VLAN Environment In addition to the default VLAN, the configuration can include
one or more other port-based VLANs and one or more
protocol VLANs. (The switches covered in this guide allow
up to 256 (vids up to 4094) VLANs of all types.) Using VLAN
tagging, ports can belong to multiple VLANs of all types.
Enabling routing on the switch enables the switch to route
IPv4 traffic between port-based VLANs and between port-
based VLANs and IPv4 protocol VLANs. Routing other types
of traffic between VLANs requires an external router
capable of processing the appropriate protocol(s).
