Chapter 2 CLI Command Summary 161

show logging events

This command displays the contents of the event log. The event log is a detailed recording of all events that take place on the system. The event log is maintained in switch memory with significant events being saved in the system log and written to disk. The event log retains approximately 2000 entries and discards old entries when it is refreshed.

This command also allows the administrator to log details about packets that have been dropped by the switch, including packets that are dropped due to filtering rules. These options should only be used for troubleshooting as using them can significantly impact performance of the switch. Once you set these options, they remain on until cleared by a subsequent show logging events command.
