5.5 VLANs
A local area network (LAN) can be divided into
multiple distinct virtual LANs (VLANs) with the use of
VLAN switches. This improves the management and
security of the network. The broadcast domain of a
device on a VLAN is confined to all devices on the
same VLAN.
The Network → VLAN page contains the sections for
VLAN Management and VLAN Ethernet Trunk.
5.5.1 VLAN Management
The VLAN Management section controls individual
VLANs according to the IEEE802.1Q standards. Within
the subsection for VLAN entries, each row represents
one VLAN ID.
The first row is given by default. It is the native or
untagged VLAN.
Add: Inserts a new row corresponding to a new VLAN.
The IP address field should be distinct for different
devices.
Managed VLAN: Allows computers on this VLAN to
access the device's configuration web page.
VLAN ID: Specifies the identifier for the VLAN. It is an
integer from 2 to 4094. Let VID be this number. The
“eth0” port is tagged with VID to give “eth0.VID”. T his
port can have multiple tags corresponding to different
VLANs. An “eth0.VID” port would only accept frames
that have been tagged with the VLAN ID VID.
Priority: Chooses the priority for transmitting packets.
This is a number from 0 to 7. The number 7
represents the highest priority.
IP address: Sets the IP address of the radio as seen by
other devices on this VLAN.
Netmask: States the netmask of the subnet defined
by this VLAN.
Bridge WIFI: Selects the wireless network for which
its interface would be bridged to the “eth0.VID” port.
The choice All Others would select all other wireless
networks that are currently not selected.
Wifi Tagging: Should be set to Enabled. This tags the
Ethernet frames sent over Wifi. This does not add a
second tag (QinQ). The wireless interface “ath0” of
this VLAN would be tagged to give “ath0.VID” for
example.
Description: Provides a short description of the VLAN.
5.5.2 VLAN Ethernet Trunk
The VLAN Ethernet Trunk uses a wireless network as a
trunk link to connect physically separate VLANs
having the same VLAN ID.
Within the subsection for the VLAN Ethernet Trunk
Entries, each row represents one VLAN ID.
Ethernet Trunk VLAN ID: Sets the VLAN ID of the
separate VLANs to connect.
Priority: Chooses the priority for transmitting packets.
This is a number from 0 to 7. The number 7
represents the highest priority.
Bridge WIFI: Selects the wireless network that would
act as a trunk link.
5.6 Hostnames
In the Network → Hostnames page, you can specify
custom hostnames (URLs) with their respective IP
addresses. This is an additional local DNS.
