Use the auth-port command to set the priority for RADIUS authentication. The auth-port command is accessible from the vnsmode:radius:<named_ RADIUS_server> context of the CLI. If you do not change the authentication port number with this command, the controller uses the default port 1812.
0-65535 | Specifies the RADIUS authentication port. |
The following example sets the port for RADIUS authentication to port 1816 for the RADIUS server named RAD1:
