Double Vlan Command List - D-Link DES-3852 - xStack Switch - Stackable Cli Manual

xStack DES-3800 Series Layer 3 Stackable Fast Ethernet Managed Switch CLI Manual
Along with normal VLAN configurations, this Switch now incorporate Double VLANs. Better known as Q-IN-Q VLANs, Double
VLANs allow network providers to expand their VLAN configurations to place VLANs within a larger inclusive VLAN, which adds
a new layer to the VLAN configuration. This basically lets large ISP's create L2 Virtual Private Networks and also create transparent
LANs for their customers, which will connect two or more customer LAN points without over complicating configurations on the
client's side. Not only will over-complication be avoided, but now the administrator has over 4000 VLANs in which over 4000
VLANs can be placed, therefore greatly expanding the VLAN network.
Implementation of this feature adds a VLAN frame to an existing VLAN frame for the ISP VLAN recognition and classification. To
ensure devices notice this added VLAN frame, an Ethernet encapsulation, here known as a tpid, is also added to the frame. The device
recognizes this tpid and therefore checks the VLAN tagged packet to see if a provider VLAN tag has been added. If so, the packet is
then routed through this provider VLAN, which contains smaller VLANs with similar configurations to ensure speedy and guaranteed
routing destination of the packet.
The VLAN commands in the Command Line Interface (CLI) are listed (along with the appropriate parameters) in the following table.
Command
enable double_vlan
disable double_vlan
create double_vlan
config double_vlan
delete double_vlan
show double_vlan
Each command is listed, in detail, in the following sections.

Example usage:
To enable the Double VLAN feature on the Switch, thus disabling normal VLANs and GVRP.
Parameters
<vlan_name 32> spvid <vlanid 1-4094> {tpid <hex 0x0-
0xffff>}
<vlan_name> {[add [uplink | access] | delete] <portlist>
| tpid <hex 0x0-0xffff>}
<vlan_name>
{<vlan_name>}
Used to enable the Double VLAN feature on the Switch.
enable double_vlan
This command, along with the disable double_vlan command,
enables and disables the Double Tag VLAN. When Double VLANs
are enabled, the system configurations for VLANs will return to the
default setting, in order to enable the Double VLAN mode. In the
Double VLAN mode, normal VLANs and GVRP functions are
disabled. The Double VLAN default setting is disabled.
None.
Only Administrator or Operator-level users can issue this command.
