To configure reverse lookup (Logs > Events > reverse lookup):
Reverse lookup is disabled by default. Enable this feature unless you have no DNS server configured or
have poor network performance because of heavy network traffic.
With reverse lookup enabled, when a network-related event occurs, both the IP address and the domain
name for the networked device associated with the event are logged in the event log. If no domain name
entry exists for the device, only its IP address is logged with the event. Since domain names generally
change less frequently than IP addresses, enabling reverse lookup can improve the ability to identify
addresses of networked devices that are causing events.
To resize the event log (Logs > Events > size):
By default, the event log stores 400 events. You can change the number of events the log stores. When
you resize the event log, all existing log entries are deleted. To avoid losing log data, use FTP or SCP to
retrieve the log before you enter a new value in the Event Log Size field.
See “How to use FTP or SCP to retrieve log files” on page 53.
When the log is full, the older entries are deleted.
