LABEL

DESCRIPTION

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.
