Troubleshooting 10/100Base-TX/9000

Diagnostic Flowcharts

Flowchart 7 Procedures

A.Execute: linkloop to remote host. Enter the PPA (NMID) of your 10/100Base-TX card and link level address (station address) of the remote host in hexadecimal form (preceded by “0x”). Execute lanscan (1M) on the local system to find the PPA (NMID) and obtain the link level address (station address) of the remote host. For more information on linkloop, refer to the linkloop(1M) online man page.

B.linkloop successful? If the test was successful, go to flowchart 1 to verify that the problem is solved. Network connectivity is o.k. through the Link Layer (OSI Layer 2). If not successful, note which error was returned and continue with this flowchart.

C.Loopback failed: Address has bad format. The link level address is not correct. Go to F.

D.Loopback failed: Not an individual address. The link level address is not correct. The first hexadecimal digit has its high order bit set (if the value is equal to or greater than 8, it is set). This means it is a multicast or broadcast address, which is not allowed. The address must be unique to one remote host. Go to F.

F.Loopback failed. The remote host did not respond. Go to G.

Correct the link address parameter. Change the link level address to an allowed value and start again with flowchart 7.

G.Choose a different remote host; re-execute linkloop. Restart flowchart 7 using a different remote host.

H.linkloop successful? If the test was successful, go to step I. Network connectivity is o.k. through the Link Layer (OSI Layer 2). If not successful, the problem may be with the remote system. Go to flowchart 6.

I.Check remote host's connectivity to 10/100Base-TX. Contact the node manager of the remote host. Check that the host is configured
