■
Protocol suite — The protocol family that is associated with a
protocol-based VLAN. Protocol-based VLANs can be associated with
one or more protocol suites. The protocol suite is unspecified for the
default VLAN and all port-based VLANs.
■
Layer 3 address — The network or subnetwork address that is
associated with a network-based IP VLAN.
■
Tagging type — On a per-port basis, whether there is explicit VLAN
membership information (the IEEE 802.1Q header and the VLAN ID or
VID) in each frame. You can specify no tagging or IEEE 802.1Q
tagging.
■
Port membership — The bridge ports that you assign to be part of
the VLAN.
If you have created trunks, you must specify the anchor port (the
lowest-numbered port) port in the trunk when you define the VLAN
interface. All bridge ports are initially part of the default VLAN.
■
VLAN name — The name that you assign to the VLAN. It can contain
up to 32 ASCII characters. If the name includes spaces, enclose the
name in quotation marks. The default VLAN uses the name Default.
■
Dynamic VLAN configuration — Using the GARP VLAN Registration
Protocol (GVRP), this configuration enables dynamic VLAN
configuration of port-based VLANs and dynamic updates of IEEE
802.1Q tagged port-based VLANs.
■
Ingress and egress rules — Ingress rules determine the VLAN to
which an incoming frame belongs. If it cannot be assigned to any
VLAN, it is assigned to the null VLAN, which contains no ports and has
no associated address table in allClosed mode.
Egress rules determine
whether the frame is forwarded, flooded, or filtered, as well as the tag
status of the transmitted frame. For more information, see “Rules of
VLAN Operation” later in this chapter.
