Only users belonging to the Super Admin User Group or users with write access to FM Security Management category can use the Authentication Type > RADIUS to add entries to GigaVUE‑FM’s list of available RADIUS authentication servers.
You can add multiple RADIUS servers. Servers are used as fallbacks in the same order they are specified – if the first server is unreachable, the second is tried, and so on, until all named servers have been used. If a server is reachable and authentication fails, the authentication process terminates.
Note: If you are deploying GigaVUE‑FM inside AWS, make sure to provide the private IP address of GigaVUE‑FM to the Radius server for authentication and not its public IP address. For more information about AWS, refer to the Gigamon Visibility Platform for AWS Getting Started Guide.
