8Authentication156The RADIUS Vendor IDWhen configuring the RADIUS server itself to receive requests from the SEG, it is important toenter a value for the Vendor ID (vid). This value should be specified as 5089.Example: Configuring a RADIUS serverIn this example, a RADIUS server will be configured with an IPv4 address of 198.10.2.1 and theshared secret specified as mysecret.Device:/> add RadiusServer IPAddress=198.10.2.1 SharedSecret=mysecretUsing RADIUS AuthenticationA RADIUS server is used for authentication with the following steps:1. Create a RADIUS server object as described above.2. Create an Authentication Profile object that uses the RADIUS server as its AuthenticationSource.3. Associate the profile with an IP rule. When the IP rule triggers, authentication of usercredentials will then be required to set up the traffic flow.The radiussnoop commandTo troubleshoot problems, the SEG provides the ability to examine the interactions that takeplace between the SEG and RADIUS servers. This is done using the CLI command radiussnoop.The command works in a similar way to the ike ‐snoop command. It is enabled from the CLIconsole and while it is enabled, any interactions with RADIUS servers is shown in consoleoutput messages. The amount of detail in this output can be adjusted.
