DOUBLE VLAN TUNNELING Double VLAN Tunneling allows the use of a second tag on network traffic. The additional tag helps differentiate between customers in the Metropolitan Area Networks (MAN) while preserving individual customer's VLAN identification when they enter their own 802.1Q domain. With the introduction of this second tag, you do not need to divide the 4k VLAN ID space to send traffic on an Ethernet-based MAN. With Double VLAN Tunneling enabled, every frame that is transmitted from an interface has a DVlan Tag attached while every packet that is received from an interface has a tag removed (if one or more tags are present). Use the Double VLAN Tunneling page to configure Double VLAN frame tagging on one or more ports. To access the Double VLAN Tunneling page, click LAN > L2 Features > VLAN > Double VLAN in the navigation tree. Document 34CSFP6XXUWS-SWUM100-D7 Multiple Port Mirroring Page 117
