Static Virtual LANs (VLANs)
Static VLAN Operation
Port-Based VLANs Protocol-Based VLANs

VLAN
Membership A port can be a member of one untagged, port-
based VLAN. All other port-based VLAN
assignments for that port must be tagged. A port can be an untagged member of one protocol
VLAN of a specific protocol type (such as IPX or IPv6).
If the same protocol type is configured in multiple
protocol VLANs, then a port can be an untagged
member of only one of those protocol VLANs. For
example, if you have two protocol VLANs, 100 and
200, and both include IPX, then a port can be an
untagged member of either VLAN 100 or VLAN 200,
but not both VLANs.
A port’s untagged VLAN memberships can include up
to four different protocol types. This means that a port
can be an untagged member of one of the following:
• Four single-protocol VLANs
• Two protocol VLANs where one VLAN includes a
single protocol and the other includes up to three
protocols
• One protocol VLAN where the VLAN includes four
protocols

based VLAN. See above.
Routing The switch can internally route IP (IPv4) traffic
between port-based VLANs and between port-
based and IPv4 protocol-based VLANs if the switch
configuration enables IP routing.
If the switch is not configured to route traffic
internally between port-based VLANs, then an
external router must be used to move traffic
between VLANs. If the switch configuration enables IP routing, the
switch can internally route IPv4 traffic as follows:
• Between multiple IPv4 protocol-based VLANs
• Between IPv4 protocol-based VLANs and port-
based VLANs.
Other protocol-based VLANs require an external
router for moving traffic between VLANs.
Note: NETbeui and SNA are non-routable protocols.
End stations intended to receive traffic in these
protocols must be attached to the same physical
network.

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 2-51.)
