Figure 86 ARP Inspection Port Configure
Syslog rate 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 (Chapter 29 on page 217) 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 10 syslog messages every 2 seconds.
Log interval 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.
Apply 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.
Cancel Click this to reset the values in this screen to their last-saved values.
