VLAN overview

The following sections provide details about the VLAN types and features supported on the

TurboIron X Series family of switches.

Types of VLANs

This section describes the VLAN types supported on devices.

VLAN support

The first software release for the TurboIron X Series supports Layer 2 port-based VLANs only. A

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

broadcast domain. The next section provides more details.

Layer 2 port-based VLANs

On all devices, you can configure port-based VLANs. A port-based VLAN is a subset of ports on a

device that constitutes a Layer 2 broadcast domain.

By default, all the ports on a device are members of the default VLAN. Thus, all the ports on the

device constitute a single Layer 2 broadcast domain. You can configure multiple port-based VLANs.

When you configure a port-based VLAN, the device automatically removes the ports you add to the

VLAN from the default VLAN.
