AAA and RADIUS
Protocol Configuration
Example
For the hybrid configuration example of AAA/RADIUS protocol and 802.1x protocol,
refer to “802.1x Configuration Example” on page 403.
Configuring the FTP/Telnet User Authentication at a Remote RADIUS Server
Configuring Telnet user authentication at the remote server is similar to configuring
FTP users. The following description is based on Telnet users.
Networking Requirements
In Figure 110, it is required to configure the remote RADIUS authentication of Telnet
users.
One RADIUS server (as authentication server) is connected to the Switch and the
server IP address is 10.110.91.146. The password for exchanging messages between
the Switch and the authentication server is "expert”. The Switch cuts off the domain
name from username and sends the remaining part to the RADIUS server.
