Configuring Dynamic Vlan Assignment - H3C S5600 SERIES Operation Manual

If you configure only a separate authentication scheme (that is, there are no separate authorization
and accounting schemes configured), the combined scheme is used for authorization and
accounting. In this case, if the combined scheme uses RADIUS or HWTACACS, the system never
uses the secondary scheme for authorization and accounting.
If you configure no separate scheme, the combined scheme is used for authentication,
authorization, and accounting. In this case, if the system uses the secondary local scheme for
authentication, it also does so for authorization and accounting; if the system uses the first scheme
for authentication, it also does so for authorization and accounting, even if authorization and
accounting fail.

Configuring Dynamic VLAN Assignment

The dynamic VLAN assignment feature enables a switch to dynamically add the switch ports of
successfully authenticated users to different VLANs according to the attributes assigned by the
RADIUS server, so as to control the network resources that different users can access.
Currently, the switch supports the following two types of assigned VLAN IDs: integer and string.
Integer: If the RADIUS authentication server assigns integer type of VLAN IDs, you can set the
VLAN assignment mode to integer on the switch (this is also the default mode on the switch). Then,
upon receiving an integer ID assigned by the RADIUS authentication server, the switch adds the
port to the VLAN whose VLAN ID is equal to the assigned integer ID. If no such a VLAN exists, the
switch first creates a VLAN with the assigned ID, and then adds the port to the newly created
VLAN.
String: If the RADIUS authentication server assigns string type of VLAN IDs, you can set the VLAN
assignment mode to string on the switch. Then, upon receiving a string ID assigned by the RADIUS
authentication server, the switch compares the ID with existing VLAN names on the switch. If it
finds a match, it adds the port to the corresponding VLAN. Otherwise, the VLAN assignment fails
and the user fails the authentication.
In actual applications, to use this feature together with Guest VLAN, you should better set port control to
port-based mode. For more information, refer to Basic 802.1x Configuration of 802.1x and System
Guard Operation.
Follow these steps to configure dynamic VLAN assignment:
To do...
Enter system view
Create an ISP domain and
enter its view
Set the VLAN assignment
mode
Create a VLAN and enter its
view
Set a VLAN name for VLAN
assignment
Use the command...
system-view
domain isp-name
vlan-assignment-mode
{ integer | string }
vlan vlan-id
name string
2-6
Remarks
—
—
Optional
By default, the VLAN assignment
mode is integer.
—
This operation is required if the
VLAN assignment mode is set to
string.
