When configuring an ArubaOS-CX switch to send RADIUS debug messages to a central SIEM server, it is important to correctly direct these debug outputs. The command debug radius all activates debugging for all RADIUS processes, capturing detailed logs about RADIUS operations. If the SIEM server is already defined on the switch for logging purposes (as indicated by the command logging 10.5.6.12), the correct destination for these debug messages to be sent to the SIEM server would be through the syslog. This ensures that all generated logs are forwarded to the centralized server specified for logging, enabling consistent log management and analysis. Using syslog as the destination leverages the existing logging setup and integrates seamlessly with the network's centralized monitoring systems.
