VLAN
VLAN Configuration
Port/VLAN VLANs are logical subgroups of a Local Area Network (LAN) created via software rather than defining a
hardware solution. VLANs combine user stations and network devices into a single domain regardless of the
physical LAN segment to which they are attached. VLANs allow 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 functioning 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.
RADIUS
Mode. Choose the function to Enable or Disable RADIUS.
RADIUS IP. Enter the 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 device and the RADIUS server. This key must match the RADIUS server encryption key. If no
host-specific value is specified, the global value applies to each host.
Administration State. Specifies the port authorization state. The possible field values are:
• Auto. The controlled port state is set by the Authentication method.
• Force Authorized. The controlled port state is set to Force-Authorized (forward traffic).
• Force Unauthorized. The controlled port state is set to Force-Unauthorized (discard traffic).
