26.7.1 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
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 41 on
page 391 ) 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.
