components of the DPI blade. If you are not sure whether a problem is caused
by the hardware or by the software, you can use the diagnostic programs to
confirm that the hardware is working correctly.
Action
v
To run the diagnostics application from the Web
Management Interface on the ASM, click
Configuration → App Manager→ DPPM, select the file
pn41_diag.csa and click Commit now.
To generate test packets while you run the DPI blade
diagnostic program, you must use a packet. When the
first packet is detected by the DPI blade diagnostic
program, it generates test packets through the various
data paths on the system.
v To view statistics that are generated by the tool, click
Software → Variable Export.
v If the counters on the Variable Export screen are not
incrementing, you can attach a notebook computer to
the SFP-module port and send a ping to initialize the
DPI blade diagnostics program.
Note: None of the error counters should be
incrementing.
v If there are errors, restart the ASM and run the test
again.
v Reseat the DPI blade and run the diagnostic test
again.
v If errors remain, there is a hardware problem, and the
DPI blade must be repaired.
The diagnostic application runs until it is terminated. Run
the application for approximately 3 minutes to get
accurate results.
v To stop the test, select the Test_Loop_Flag check
box and click Clear Selected. After the test is
terminated, you can start another application. You
must stop the diagnostic test before you start another
application.
