• If loopback failed error = “Address has bad format” or “Not an
individual address” then correct the link level address with the
proper station address format/value and repeat the Link Level Test.
• Otherwise, loopback failed because the remote host did not respond.
Double check the remote host address or choose another remote host
and re-execute linkloop(1M). If linkloop(1M) is successful, continue
to Network Test. You may also want to contact the administrator of
the remote that did not respond (if this was the case).
