Chapter 5: Setting Up SafeGuard Switches
Setting the Retry Limit
By default, the system retries an ARP request up to 4 times. Use the arp retries command
to change the maximum retry limit. Use the no version of the command to reinstate the
default retry limit to 4 tries. The syntax of the Global Configuration commands are:
arp retries attempts
no arp retries
The following example sets the retry limit to 8 retries.
(SafeGuardOS) #configure terminal
Enter configuration commands, one per line. End with CNTL/Z
(SafeGuardOS) (config) #arp retries 8
(SafeGuardOS) (config) #exit
(SafeGuardOS) #
Changing the ARP Timer
An ARP entry ages out of the ARP cache after 20 minutes. To change the ARP entry age
timeout, use the arp timeout Global Configuration command. Use the no version of the
command to reinstate the default value of 1200 seconds.
arp timeout seconds
no arp timeout
The following example sets the age out time to 5 minutes.
(SafeGuardOS) #configure terminal
Enter configuration commands, one per line. End with CNTL/Z
(SafeGuardOS) (config) #arp timeout 60
(SafeGuardOS) (config) #exit
(SafeGuardOS) #
Clearing the ARP Cache
To clear the ARP cache of dynamic (and gateway) entries, use the clear arp-cache
command in Privileged Exec mode. If the gateway parameter is specified, dynamic
entries of type gateway are also removed. This command does not clear static entries.
Syntax Description attempts Specifies the maximum number of request for
retries. Valid values are 0 to 10 retries.
Syntax Description seconds Specifies the amount of time in seconds
before an ARP entry ages out. Valid entries
are 15 to 21600 seconds. The default value is
1200 seconds.
