Basic Syslog Scenario

Basic Syslog Scenario shows a basic scenario of how Syslog components operate on an Extreme Networks switch. By default, all applications running on the Extreme Networks switch are allowed to forward Syslog messages generated at severity levels 6 through 1. In the configuration shown, these default settings have not been changed.

Default application settings in the example in Basic Syslog Scenario have not been modified. Therefore, an emergency message triggered by a system reset due to loss of the master module is forwarded to Syslog destinations. The CLI-related message notifying that a user has logged in remotely is also forwarded. Configured Syslog server(s) will receive all forwarded messages since their default severity threshold is at 8 (accepting messages at all severity levels).

Any messages generated by applications at severity levels 7 and 8 are not forwarded in this example. For instance, forwarding does not occur for an AAA authentication-related debugging message with information about RADIUS access level processing for a particular user. If at some point in time it becomes necessary, for example, to log all AAA authentication-related message activity and to save it to a file so authentication details can be tracked, the administrator can allow that specific application to forward debugging messages to a Syslog server, as well as to the console and persistent file storage.
