Flowchart 2 Procedures

•Execute linkloop(1M) to remote host. If linkloop is successful, continue to Network Level Tests. Otherwise, note which error was returned.

•If loopback failed error = “Address has bad format” or “Not an individual address,” correct link level address with proper station address format/value and repeat Link Level Test.

•Otherwise, loopback failed because remote host did not respond. Double check remote host address or choose another remote host and re-execute linkloop(1M). If linkloop is successful, continue to Network Level Tests. You may also want to call the node manager of the remote host that did not respond (if this was the case). If linkloop fails, go to Configuration Tests.
