Figure 57. Configuring VLAN for VAP interfaces
17.2 Gateway Configuration
For VLAN tags to be preserved on traffic that exits a mesh neighborhood, VLAN support must
be enabled for the Ethernet interface on the mesh neighborhood’s gateway device (the
backhaul interface). The “Enable VLAN” parameter for the Wired/Backhaul interface controls
the state of VLAN tagging. If VLAN tagging is enabled on the gateway’s interface to the WAN,
all outbound traffic will have its VLAN tags preserved. If VLAN tagging is disabled for the
backhaul interface, all VLAN tags will be stripped from frames entering the mesh
neighborhood.
When VLAN is enabled for the backhaul interface, data frames forwarded by the gateway to
the WAN will preserve their existing VLAN tag, if they have one. Frames that do not have a tag
will be tagged with the default VLAN ID for the gateway’s Ethernet interface. The VLAN ID
