Troubleshooting HP-UX IPQoS
Troubleshooting Scenarios
Chapter 6 105
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
-verbose option 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.
Active Configuration Is Not As Expected
Problem
The HP-UX IPQoS active configuration is not what you expected.
Symptoms

Solution
Examine closely the filters, policies, and adapters in the configuration file. Look for
typographical errors or incorrect definitions. When you find the cause for any discrepancies,
modify the configuration file as needed and reload it, using the following command:
#ipqosadmin -load -f fixed_filename -verbose
State Is Not As Expected
Problem
The state of HP-UX IPQoS is not what you expected.
