6.8.3 System Event Log—Event Configuration
Having ticked the Syslog/SMTP checkboxes, the event log/email alert will be sent to the
system log server and the SMTP server respectively. Also, Port event log/alert (link up, link
down, and both) can be sent to the system log server/SMTP server respectively by setting
the trigger condition.
 System event selection: There are 3 event types—Device Cold Start, Authentication
Failure, and X-ring Topology Change. The checkboxes are not available for ticking
unless the Syslog Client Mode on the Syslog Configuration tab and the E-mail Alert
on the SMTP Configuration tab are enabled first.
 Device cold start: When the device executes cold start action, the system will
issue the event log/email alert to the system log/SMTP server respectively.
 Authentication Failure: When the SNMP authentication fails, the system will
issue the event log/email alert to the system log/SMTP server respectively.
 X-ring topology change: When the X-ring topology has changed, the system will
issue the event log/email alert to the system log/SMTP server respectively.
 Port event selection: Also, before the drop-down menu items are available, the
Syslog Client Mode selection item on the Syslog Configuration tab and the E-mail
Alert selection item on the SMTP Configuration tab must be enabled first. Those drop-
down menu items have 3 selections—Link UP, Link Down, and Link UP & Link
Down. Disable means no event will be sent to the system log/SMTP server.
 Link UP: The system will only issue a log message when the link-up event of the
port occurs.
 Link Down: The system will only issue a log message when the link-down event
of port occurs.
 Link UP & Link Down: The system will issue a log message at the time when port
connection is link-up and link-down.
