Note: If the incoming packet from the End-user is untagged and the egress
tag VLAN ID is set to transparent, then the outgoing packet is sent as
untagged, regardless of how the second_tag and the tag Ethertype
are configured.
Explanation of terms:
tagged <Idy>: VLAN ID for outer VLAN.
tagged <Idx>: VLAN ID for inner VLAN. Note that <Idx> is also used
when there is only one VLAN tag in the outgoing packet.
<Ethertype>: Ethertype. The following types can be specified:
q_vlan (0x8100)
s-vlan (0x88A8)
vman_vlan (0x9100)
s_vlan (0x9200)
Not applicable: This value must be specified in the CLI, but is ignored later
in the VLAN mapping.
Note that VLAN ID is called tag or second_tag and Ethertype is called
first_ethertype or second_ethertype in the CLI.

switch for ports belonging to a particular VLAN. The switching domain is
