Chapter 26 IP Source Guard Table 119 ARP Inspection Configure (continued) LABEL Syslog rate Log interval Apply Cancel 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 (Chapter 39 on page 358) 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. 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 ARP packets on each untrusted port. To 266 VES1724-56 User's Guide

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
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 39 on
page 358
) 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
