VLAN Management

VLAN Manager

VLAN Manager allows you to manage Virtual Local Area Networks (VLANs) on Brocade products.

You can use VLAN Manager to configure port VLANs. By default, interfaces on a Brocade device

that are not assigned to a VLAN are members of the default port VLAN; therefore, all device

interfaces assigned to the default VLAN constitute a single Layer 2 broadcast domain.

When you assign an interface to a port VLAN, that interface is automatically removed from VLAN 1.

Interfaces assigned to port VLANs can be defined as untagged, tagged, and converged ports. An

untagged port can be a member of only one VLAN, while a tagged port can be a member of more

than one VLAN. Interfaces defined as converged allow tagged and untagged traffic to pass through

an interface at the same time.

When you enable port-based VLANs, all ports in the system are added to the default VLAN. By

default, the default VLAN ID is 1. The default VLAN is configurable. If you want to use the VLAN ID

"VLAN 1" as a configurable VLAN, you can assign a different VLAN ID to the default VLAN.

You must specify a valid VLAN ID that is not already in use. For example, if you have already defined

VLAN 10, do not try to use "10" as the new VLAN ID for the default VLAN. Valid VLAN IDs are 1

through 4095.

Default VLANs are not configurable on Data Center Bridging (DCB) products.

A super aggregated VLAN allows multiple VLANs to be placed within another VLAN. This feature

allows you to construct Layer 2 paths and channels. It is useful for Virtual Private Network (VPN)

applications in which you need to provide a private, dedicated, Ethernet connection for an

individual client who can transparently reach its subnet across multiple networks.
