Tunnel-Private-Group-ID = 1u,2t [VLAN ID list]
The VLAN identifier list is carried in the RADIUS “Tunnel-Private-Group-ID”
attribute. The VLAN list can contain multiple VLAN identifiers in the format
“1u,2t,3u” where “u” indicates an untagged VLAN and “t” a tagged VLAN.
◆ The RADIUS server may optionally return dynamic QoS assignments to be
applied to a switch port for an authenticated user. The “Filter-ID” attribute
(attribute 11) can be configured on the RADIUS server to pass the following
QoS information:
◆ Multiple profiles can be specified in the Filter-ID attribute by using a semicolon
to separate each profile.
For example, the attribute “service-policy-in=pp1;rate-limit-input=100”
specifies that the diffserv profile name is “pp1,” and the ingress rate limit profile
value is 100 kbps.
◆ If duplicate profiles are passed in the Filter-ID attribute, then only the first
profile is used.
For example, if the attribute is “service-policy-in=p1;service-policy-in=p2”, then
the switch applies only the DiffServ profile “p1.”
◆ Any unsupported profiles in the Filter-ID attribute are ignored.
For example, if the attribute is “map-ip-dscp=2:3;service-policy-in=p1,” then
the switch ignores the “map-ip-dscp” profile.
◆ When authentication is successful, the dynamic QoS information may not be
passed from the RADIUS server due to one of the following conditions
(authentication result remains unchanged):
■
The Filter-ID attribute cannot be found to carry the user profile.
■
The Filter-ID attribute is empty.
■
The Filter-ID attribute format for dynamic QoS assignment is
unrecognizable (can not recognize the whole Filter-ID attribute).
