26.10.1 ARP Inspection Port Configure
Use this screen to specify whether ports are trusted or untrusted ports for ARP inspection. You can also
specify the maximum rate at which the Switch receives ARP packets on each untrusted port. To open
this screen, click Advanced Application > IP Source Guard > IPv4 Source Guard Setup > ARP Inspection >
Configure > Port.

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 47 on page
395) 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.
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.
