802.1X port security configuration
If one of the attributes in the Access-Accept message specifies a VLAN identifier, and if this VLAN is
available on the Brocade device, the client port is moved from its default VLAN to this specified
VLAN.
NOTE
This feature is supported on port-based VLANs only. This feature cannot be used to place an
802.1X-enabled port into a Layer 3 protocol VLAN.
Automatic removal of dynamic VLAN assignments for 802.1X ports
For increased security, this feature removes any association between a port and a
dynamically-assigned VLAN when all 802.1x sessions for that VLAN have expired on the port.
NOTE
When a show run command is issued during a session, the dynamically-assigned VLAN is not
displayed.
Enable 802.1X VLAN ID support by adding the following attributes to a user profile on the RADIUS
server.
The device reads the attributes as follows:
•If the Tunnel-Type or the Tunnel-Medium-Type attributes in the Access-Accept message do not
have the values specified above, the Brocade device ignores the three Attribute-Value pairs.
The client becomes authorized, but the client port is not dynamically placed in a VLAN.
•If the Tunnel-Type or the Tunnel-Medium-Type attributes in the Access-Accept message do have
the values specified above, but there is no value specified for the Tunnel-Private-Group-ID
attribute, the client will not become authorized.
•When the Brocade device receives the value specified for the Tunnel-Private-Group-ID
attribute, it checks whether the vlan-name string matches the name of a VLAN configured on
the device. If there is a VLAN on the device whose name matches the vlan-name string, then
the client port is placed in the VLAN whose ID corresponds to the VLAN name.
•If the vlan-name string does not match the name of a VLAN, the Brocade device checks
whether the string, when converted to a number, matches the ID of a VLAN configured on the
device. If it does, then the client port is placed in the VLAN with that ID.
•If the vlan-name string does not match either the name or the ID of a VLAN configured on the
device, then the client will not become authorized.
The show interface command displays the VLAN to which an 802.1X-enabled port has been
dynamically assigned, as well as the port from which it was moved (that is, the port default
VLAN).Refer to “Displaying dynamically assigned VLAN information” on page188 for sample output
indicating the port dynamically assigned VLAN.
TABLE 26 802.1X VLAN ID attributes
Attribute name Type Value
Tunnel-Type 064 13 (decimal) – VLAN
Tunnel-Medium-Type 065 6 (decimal) – 802
Tunnel-Private-Group-ID 081 vlan-name (string) – either the name or the number of a VLAN
configured on the Brocade device.
