    Remote authentication: Users are authenticated remotely through RADIUS or HWTACACS protocol. This device (for example, a H3C series switch) acts as the client to communicate with the RADIUS or TACACS server. For RADIUS protocol, you can use extended RADIUS protocol as well as standard RADIUS protocol.
