Attribute-Specific Field Used to assign the 802.1p default
priority of the port.
0-7 Required
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:
