Enabling support for portal user moving
Only Layer 2 portal authentication supports this feature.
In scenarios where there are hubs, Layer 2 switches, or APs between users and the access devices, if an authenticated user moves from the current access port to another Layer 2-portal-authentication-enabled port of the device without logging off, the user cannot get online when the original port is still up. The reason is that the original port is still maintaining the authentication information of the user and the device does not permit such a user to get online from another port by default.
To solve the problem described above, enable support for portal user moving on the device. Then, when a user moves from a port of the device to another, the device provides services in either of the following ways:
If the original port is still up and the two ports belong to the same VLAN, the device allows the user to continue to access the network without re-authentication, and uses the new port information for user accounting.
If the original port is down or the two ports belong to different VLANs, the device removes the authentication information of the user from the original port and authenticates the user on the new port.
To enable support for portal user moving:
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Enable support for portal user moving. | portal move-mode auto | Disabled by default |
For a user with authorization information (such as authorized VLAN) configured, after the user moves from a port to another, the switch tries to assign the authorization information to the new port. If the operation fails, the switch deletes the user's information from the original port and re-authenticates the user on the new port.
