The authentication port-vlan-modify user-online command enables the function of keeping users online when the port type or VLAN is changed.
The undo authentication port-vlan-modify user-online command restores the default setting.
By default, the function of keeping users online when the port type or VLAN is changed is disabled.
Usage Scenario
After user access authentication succeeds, you can change the VLAN allowed to access or the access interface type through the RADIUS server. For example, you can assign VLANs to clients through the server for network planning and deployment. After the deployment is complete, to reduce the impact of link faults and device restart on the network and implement rapid network restoration, you can change the user access VLAN to the authorized VLAN. In this case, you can enable the function of keeping users online when the port type or VLAN is changed to modify interface or VLAN configurations.
Precautions
This function is only supported by MAC and 802.1X authentication.
