To receive information messages sent when verifying or loading a configuration file, use
the -verbose option. Run the following command:
#ipqosadmin -verify|-load -f filename -verbose
Examine error, warning and informative messages for any unexpected information.
• Examine the active configuration and determine if it meets your expectations. Run the
following command:
#ipqosadmin -showconfig
• Examine the statistics collected on the active configuration and determine if the policies
are behaving as you expected. Run the following command:
#ipqosadmin -showstats
If statistics do not match your expectations, and you’ve ensured your configuration
matches your expectations, monitor network traffic to see if conditions have changed such
that changes to the active configuration are warranted.
HP-UX System and Networking Utilities
You can use the same HP-UX system and networking utilities you typically use to get
information about the network.
Some of the general networking utilities available include the following:
• netstat
• ifconfig
• syslog
• nettl
• traceroute
• route
• ping
• lanadmin
Refer to the manpages for these utilities to get more information on how to use these utilities
and how to interpret their output.
Public domain utilities such as tcpdump and MRTP (multi-router traffic grapher) can also
provide helpful information about the network. HP includes the tcpdump utility as part of the
HP-UX Internet Express bundle, available on HP Software Depot, at
