: Sets the VLAN assignment mode to integer. 

: Sets the VLAN assignment mode to string. 

Use the vlan-assignment-mode command to set the VLAN assignment mode (integer or string) on the 
switch. 

By default, the VLAN assignment mode is integer, that is, the switch supports its RADIUS 
authentication server to assign integer VLAN IDs. 

The dynamic VLAN assignment feature enables a switch to dynamically add the 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. 

In actual applications, to use this feature together with Guest VLAN, you are recommended to set port 
control to port-based mode. 

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. 

The switch supports two dynamic VLAN assignment modes to adapt to different authentication servers. 
You are recommended to configure the switch according to the dynamic VLAN assignment mode used 
by the server.
