Using this input field you assign the user an individual VLAN ID. After authentication by the RADIUS server, the individual VLAN ID overwrites a global VLAN ID that a user would otherwise obtain from the interface. The value 0 disables the assignment of an individual VLAN ID.
Note: For technical reasons, the assignment of a VLAN ID requires a new address assignment by the DHCP server. As long as a client is not yet assigned a new address after successful authentication, the client is still in the previous (e.g., untagged) network. In order for clients to be transferred to the new network as quickly as possible, it is necessary to set the lease time of the DHCP server – in the setup menu – as short as possible. Possible values (in minutes) include, for example:
- Max. lease time minutes
- 2
- Default lease time minutes
- 1
Take into account that a strong reduction in global lease time can flood your network with DHCP messages, and when there is a larger number of users, it leads to an increased network load! Alternatively, you have the option of using a different DHCP server or allowing your users to manually request a new address by using their client. In the Windows command line this is done, for example, using the commands ipconfig /release and ipconfig /renew.
Note: By assigning a VLAN-ID, the user loses his connection after the initial DHCP lease expires. The connection only remains stable as of the second lease, i.e. after successfully assigning the VLAN-ID.
