VLAN overview

The following sections provide details about the VLAN types and features supported on the FastIron
family of switches.

Types of VLANs

This section describes the VLAN types supported on Brocade devices.

VLAN support on FastIron devices

You can configure the following types of VLANs on FastIron devices:

• Layer 2 port-based VLAN - a set of physical ports that share a common, exclusive Layer 2

broadcast domain

• Layer 3 protocol VLANs - a subset of ports within a port-based VLAN that share a common,

exclusive broadcast domain for Layer 3 broadcasts of the specified protocol type

• IP subnet VLANs - a subset of ports in a port-based VLAN that share a common, exclusive subnet

broadcast domain for a specified IP subnet

• IPv6 VLANs - a subset of ports in a port-based VLAN that share a common, exclusive network

broadcast domain for IPv6 packets

• IPX network VLANs - a subset of ports in a port-based VLAN that share a common, exclusive

network broadcast domain for a specified IPX network

• AppleTalk cable VLANs - a subset of ports in a port-based-based VLAN that share a common,

exclusive network broadcast domain for a specified AppleTalk cable range

When a FastIron device receives a packet on a port that is a member of a VLAN, the device forwards
the packet based on the following VLAN hierarchy:
