Flowchart 3a Procedures

•Execute ping(1M) to remote host so that ARP entry is added. Whether or not ping is successful, proceed to the next step.

•Use arp(1M) to verify that an entry exists for the remote host in your system's ARP cache, executing arp hostname.

•If there is no ARP entry for the remote host, check to see if the remote host is up. If not, bring up remote host and continue to ping Test.

•If the ARP entry is correct or complete, continue to ping Test. Otherwise, use arp(1M) to enter the correct station address of the remote system and continue to ping Test.
