VLAN Manager
NOTE
VLAN Management is not supported on Fabric OS devices.
VLAN Manager allows you to manage Virtual Local Area Networks (VLANs) on Brocade products.
You can use VLAN Manager to view existing VLAN configurations on the products and the network,
and edit the configuration on supported platforms, including Network OS platforms but not the
Brocade 6910. By default, interfaces on a 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 the
default VLAN, 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.
Default VLAN
When you enable port-based VLANs, all ports in the system are added to the default VLAN. The
default VLAN ID is 1. The default VLAN is configurable except on Network OS devices. 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
from 1 through 4095. For DCB and Network OS products, the user-configurable range is from 1
through 3583 (3584 through 4095 are reserved). When GVLAN is enabled, the VLAN range
supported for the Brocade VDX 8770 and Brocade VDX 6740 and VDX 6740-1G is from 4091
through 4095.
