If the user has configured the 802.1p priority attribute of the RADIUS server (for example, priority 7)
and the 802.1X, or Host-based authentication is successful, the device will assign the 802.1p
default priority (according to the RADIUS server) to the port. However, if the user does not
configure the priority attribute and authenticates successfully, the device will not assign a priority to
this port. If the priority attribute is configured on the RADIUS server is a value out of range (>7), it
will not be set to the device.
To assign VLAN by RADIUS Server, the proper parameters should be configured on the RADIUS
Server. To use VLAN assignment, RFC3580 defines the following tunnel attributes in RADIUS
packets.
The table below shows the parameters for a VLAN:
RADIUS Tunnel
Attribute
Tunnel-Type This attribute indicates the tunneling protocol(s)
to be used (in the case of a tunnel initiator) or
the tunneling protocol in use (in the case of a
tunnel terminatior).
Tunnel-Medium-Type This attribute indicates the transport medium
being used.
Tunnel-Private- This attribute indicates group ID for a particular
Group-ID tunneled session.
A summary of the Tunnel-Private-Group-ID Attribute format is shown below.
