The system does not try to resolve the ARP when it needs to send out the SNMP dying-gasp trap, because the amount of time available during power loss event is very less. Instead, the system assumes that ARP entry to the gateway used to reach the SNMP trap server is always available. It is recommended that user run a periodic ping query to the SNMP trap server in the background using the cron utility.
The following is an example configuration of a cron job that initiates a ping to the server mentioned in the pingscript file every one minute.
*7210-SAS># configure cron
*7210-SAS >config>cron# info
