GS2210 Series User's Guide
DESCRIPTION
Enter the maximum number of syslog messages the Switch 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
on page 320) to use this. Enter 0 if you do not want the Switch 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 Switch
sends 4 syslog messages every second.
• 6 invalid ARP packets per second, Syslog rate is 5, Log interval is 2: the Switch
sends 5 syslog messages every 2 seconds.
Enter how often (1-86400 seconds) the Switch sends a batch of syslog messages to
the syslog server. Enter 0 if you want the Switch 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 Switch's run-time memory. The Switch 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.
