OMMANDS
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.
