Hi Boyu, I think your issue is the client not renewing the IP address automatically. With WiFi, you would usually send the WiFi device or WiFi controller a Radius Disconnect or an CoA and it will bump the device momentarily and the client will ask for a new lease and target the right IP address.
I am not sure how this is done for Wired connections, I guess you need to do the same CoA or Radius disconnect to the switch port to get the client "bumped". This would be the same as you unplugging/re-plugging the Ethernet cable. Hope this points you in the right direction.
