Flowchart 4 Procedures

A,

Execute: netfmt. Use the netfmt command to view log

 

data (error and disaster messages). An example

 

command is shown below.

 

netfmt -v -f /var/adm/nettl.LOG00 more

B.

Check causes and actions on display in the

 

formatted log output. Use the time stamp to find the

 

proper logs. Ensure that you are looking at the

 

10/100Base-TX information.

C.

Problem solved. If yes, go to flowchart 1. If not,

 

continue with step D.

D.

Execute lanadmin. Run lanadmin(1M). For a

 

complete description of this command, refer to the

 

lanadmin(1M) on-line manual page.

E.

Select LAN from Menu. Select lan from the menu to

 

enter LAN Interface Diagnostic.

F.

Select the PPA (NMID) and enter the

 

10/100Base-TX NMID. You can use the lanscan

 

command to find the current PPA (NMID) for

 

10/100Base-TX. The PPA (NMID) you enter becomes

 

the current device to be tested.

G.

Reset the card according to Steps D through G in

 

Flowchart 4. Using the reset command in lanadmin

 

re-executes the LAN card self-test.

Reset successful? The reset is successful if no errors are displayed as a result of the reset command. If the self-test was successful, the problem may be that you are not connected to the 10/100Base-TX network.
