Figure 47. Configuring VLAN for access point interfaces
14.2 Gateway Configuration
For VLAN tags to be preserved on traffic that exits a mesh cluster, VLAN support must be
enabled for the Ethernet interface on the mesh cluster‟s gateway node. 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 cluster.
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
must be in the range from 0 to 4095. Note that 0 and 4095 are reserved values and 1 is the
default VLAN ID.
CLI
The example below shows how to enable VLAN tagging on the backhaul interface on a
gateway node using the „vlan.enable‟ parameter in the „eth0‟ interface.
> use eth0
eth0> set vlan.enable=yes
