Troubleshooting HP-UX IPQoS

Troubleshooting Scenarios

Solution

1.Examine the error messages that appear upon failure. Several errors such as basic syntax errors are easily diagnosed from the messages.

2.Determine if the verification is failing due to the presence of warning messages. Use the -verboseoption to display warning messages. Run the following command:

#ipqosadmin -verify -f <file> -verbose

3.Review the configuration file closely to ensure it is written as you intended. Review the syntax rules covered in Chapter 4, “HP-UX IPQoS Configuration Files,” on page 55, to make sure the file is syntactically correct.

4.Create smaller configuration files that are subsets of the problem file (with the result being fewer or simpler filters or policies) to narrow down the potential source of the problem. Repeat steps 1-3 with the smaller files until you have isolated the problem.

#ipqosadmin -load -f fixed_filename -verbose
