For a device to be authenticated and authorized at a port which is DVA-enabled:
•
The RADIUS server must authenticate the device and dynamically assign a
VLAN to the device. You can set the RADIUS VLAN Assignment field to
static in the Port Authentication page. This enables the host to be bridged
according to static configuration.
•
A RADIUS server must support DVA with RADIUS attributes tunnel-type
(64) = VLAN (13), tunnel-media-type (65) = 802 (6), and tunnel-private-
group-id = a VLAN ID.
When the RADIUS-Assigned VLAN feature is enabled, the host modes behave as
follows:
•
Single-Host and Multi-Host Mode
Untagged traffic and tagged traffic belonging to the RADIUS-assigned
VLAN are bridged via this VLAN. All other traffic not belonging to
unauthenticated VLANs is discarded.
•
Full Multi-Sessions Mode
Untagged traffic and tagged traffic not belonging to the unauthenticated
VLANs arriving from the client are assigned to the RADIUS-assigned VLAN
using TCAM rules and are bridged via the VLAN.
•
Multi-Sessions Mode in Layer 3 System Mode
This mode does not support RADIUS-assigned VLAN,
The following table describes guest VLAN and RADIUS-VLAN assignment support
depending on authentication method and port mode.
