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.
