Netgear M4300-24X24F (XSM4348S) - Stackable Managed Switch with 48x10G including 24x10GBASE-T and 24xSFP+ Layer 3 Guia Do Programa

This section describes the commands you use to configure double VLAN (DVLAN). Double 
VLAN tagging is a way to pass VLAN traffic from one customer domain to another through a 
Metro Core in a simple and cost effective manner. The additional tag on the traffic helps 
differentiate between customers in the MAN while preserving the VLAN identification of the 
individual customers when they enter their own IEEE 802.1Q domain.

This command configures the ethertype for the specified interface. The two-byte hex 
ethertype is used as the first 16 bits of the DVLAN tag. The ethertype can have the values of 
802.1Q

, vman, or custom. If the ethertype has an optional value of custom, then it is a 

custom tunnel value, and ethertype must be set to a value in the range of 1 to 65535.

This command removes the ethertype value for the interface. 

Use this command to create a new TPID and associate it with the next available TPID 
register. If no TPID registers are empty, the system returns an error. Specifying the optional 
keyword primary–tpid forces the TPID value to be configured as the default TPID at index 
0. The ethertype can have the values of 802.1Q, vman, or custom. If the ethertype has an 
optional value of custom, then it is a custom tunnel value, and ethertype must be set to a 
value in the range of 1 to 65535.
