DESCRIPTION
Enter the maximum number of syslog messages the OLT can send to the syslog server in
one batch. This number is expressed as a rate because the batch frequency is
determined by the Log Interval. You must configure the syslog server
380) to use this. Enter 0 if you do not want the OLT to send log messages generated by ARP
packets to the syslog server.
The relationship between Syslog rate and Log interval is illustrated in the following
examples:
•
4 invalid ARP packets per second, Syslog rate is 5, Log interval is 1: the OLT sends 4
syslog messages every second.
•
6 invalid ARP packets per second, Syslog rate is 5, Log interval is 2: the OLT sends 5
syslog messages every 2 seconds.
Enter how often (1-86400 seconds) the OLT sends a batch of syslog messages to the syslog
server. Enter 0 if you want the OLT to send syslog messages immediately. See Syslog rate
for an example of the relationship between Syslog rate and Log interval.
Click Apply to save your changes to the OLT's run-time memory. The OLT loses these
changes if it is turned off or loses power, so use the Save link on the top navigation panel
to save your changes to the non-volatile memory when you are done configuring.
Click this to reset the values in this screen to their last-saved values.
