Flowchart Procedures

A.

Host entry in ARP cache? Using arp, check that an

 

entry exists for the remote host in your system's ARP

 

cache. For example:

 

arp spiff

B.

Remote host up? If there is no ARP cache entry for

 

the remote host, first check that the remote host is up.

 

If not, the remote host has not broadcast an ARP

 

message, and that probably is why there is no entry in

 

the ARP cache.

C.

Bring-up remote host. Have the node manager of the

 

remote host bring that system up and start again with

 

flowchart 1.

D.

Entry complete? Perhaps there is an ARP cache

 

entry, but it is wrong or not complete. If the entry is

 

complete, go to step F.

E.

Use arp to complete entry. Using arp, enter the

 

correct Station Address. For more information, refer to

 

the arp(1M) online man page. Start again with

 

flowchart 1.

F.

ping local host. Using ping, do an internal loopback

 

on your own system. In other words, ping your own

 

system.

 

If the internal loopback is successful, your system is

 

operating properly to the Network Layer (OSI Layer 3).

 

In addition, you know an ARP cache entry for the

 

remote host exists on your system. Start again with
