network traffic to flow more efficiently within subgroups. VLANs managed through software
reduce the amount of time in which network changes are implemented.
VLANs have no minimum number of ports, and can be created per unit, per device, per stack, or
any other logical connection combination, as VLANs are software based and not defined by
physical attributes.
VLANs function at layer 2. Since VLANs isolate traffic within the VLAN, a Layer 3 router is needed
to allow traffic flow between VLANs. Layer 3 routers identify segments and coordinate with
VLANs.
VLANs are broadcast and multicast domains. Broadcast and multicast traffic is transmitted only
in the VLAN in which the traffic is generated.
This device supports up to 4 VLANs, including the default VLAN.
VLAN ID
—The VLAN ID number. This can be any number from 2 to 3290, or from 3293 to 4094.
(VLAN ID 1 is reserved for the default VLAN, which is used for untagged frames received on the
interface. VLAN IDs 3291-3292 are reserved and cannot be used.) To create a VLAN, enter the ID
number and click Add VLAN.
VLAN ID Range
—To create multiple VLANs with a range of ID numbers, enter the starting and
ending ID numbers and click Add Range.
Delete Selected VLAN
—To delete a VLAN, select it form the VLAN list and click Delete Selected
VLAN.

VLAN & Port Assignment
This Tab is a combination of Port settings and VLAN membership tabs in one on this device and
other routers.
The first section is port specific settings regarding the use of VLAN (nothing to do with
individual VLANs).
It requires users to specify the port mode for each port.
The "acceptable
frame type" and "PVID" options are for "General" port mode only
Port Mode—
select one of the three modes:
•
Access
—All frames are untagged coming in or going out of the switch port.
Wireless
port can be set to this mode only.
•
Trunk
—All frames are tagged coming in or going out of the switch except for VLAN ID 1
(called native VLAN or default VLAN in Cisco)

•
General
—All frames can be tagged or untagged coming in
to the switch.
If it is
untagged, default PVID will apply to the packet. Only the General mode users can
choose the following two options.
–
Acceptable Ingress Frame Type
—All Frames: all the incoming frames are
acceptable.
Tagged Only: only tagged incoming frames are acceptable
–
Ingress Filtering
—Check the VLAN ID on the incoming packet.
If the port is a
member of this VLAN, accept the frame. Otherwise, drop it. If not enabled, all frames
are accepted.
•
PVID
—The VLAN ID of the default (untagged) VLAN
The second section is per VLAN settings to be used with each port.
It requires users to specify
each VLAN to be tagged, untagged, or excluded on the specific port.
•
VLAN
— Select a VLAN ID to be configured
•
VLAN NAME
— VLAN description (read-only) to help user identify this VLAN
•
Tagged
— Egress frames from this port is tagged for this VLAN
•
Untagged
—Egress frames from this port is untagged for this VLAN
•
Excluded
—The port does not participate in this VLAN at all
For Access port, the available options are either untagged or excluded. Therefore, wireless port
can set to one of these two modes for each VLAN. Only one of the VLAN ID can be selected
(untagged).
For Trunk port, the options are tagged or excluded for all VLAN IDs except VLAN 1.
VLAN 1 must
be untagged.
For General port, the options are tagged or untagged for PVID; tagged or excluded for all other
VLAN IDs.
The third section is a summary of VLAN subscriptions on each port. "U" means untagged while
"T" means tagged.

The following cannot be supported on Vitesse

RADIUS
RADIUS mode provides authentication on devices connecting to the LAN ports. It requires
installation of a RADIUS server on your local network.
Mode
—Select
Enabled
or
Disabled
, as desired.
RADIUS IP
—Enter the RADIUS server IP address.
RADIUS UDP Port
—Identifies the UDP port. The UDP port is used to verify the RADIUS server
authentication.
RADIUS Secret
—Indicates the Key string used for authenticating and encrypting all RADIUS
communications between the Wireless Router and the RADIUS server. This key must match the
RADIUS server’s configuration.
Administration State
—Specifies if each port needs RADIUS authentication. The defaults are
Force Authorized
so no authentication is needed. The possible field values are:
•
Auto
—Controlled port state is set by the
RADIUS Mode
.
•
Force Authorized
—Controlled port state is set to Force-Authorized (forward traffic). All
connections can be made.
•
Force Unauthorized
—Controlled port state is set to Force-Unauthorized (discard
traffic). All connections are blocked.

Port Settings
Port
—Specifies the number of the four LAN ports.
Link
—Displays the port duplex mode (Full or Half) and speed (10/100/1000 Mbps). Full
indicates that the interface supports transmission between the device and its link partner in
both directions simultaneously. Half indicates that the interface supports transmission
between the device and the client in only one direction at a time.
Mode
—Specifies port duplex mode (Full or Half) and speed (10/100/1000 Mbps). Auto
Negotiation is a protocol between two link partners that enables a port to advertise its
transmission rate, duplex mode and flow control abilities to its partner. Default is
Auto
Negotiation
.
Flow Control
—Configures the flow control setting on the port. Select to enable. The default is
disabled.
MaxFrame
—Configures the maximum ethernet frame size sent or received on the port.
Default is 1518. You can set only to a value lower than 1518.
