Solaris 11 – How to Administrate IPQoS

How to Apply a New Configuration to the IPQoS Kernel Modules

You use the ipqosconf command to read the IPQoS configuration file and to configure the IPQoS modules in the UNIX kernel. The next procedure uses as an example the file/var/ipqos/Goldweb.qos

  1. Apply the new configuration.
    # /usr/sbin/ipqosconf -a/var/ipqos/Goldweb.qos

    ipqosconf writes the information in the specified IPQoS configuration file into the IPQoS modules in the Oracle Solaris kernel. In this example, the contents of /var/ipqos/Goldweb.qosare applied to the current Oracle Solaris kernel.

    Note – When you apply an IPQoS configuration file with the -a option, the actions in the file are active for the current session only.

  2. Test and debug the new IPQoS configuration.Use UNIX utilities to track IPQoS behavior and to gather statistics on your IPQoS implementation. This information can help you determine if the configuration operates as expected.

How to Ensure That the IPQoS Configuration Is Applied After Each Reboot

You must explicitly make an IPQoS configuration persistent across reboots. Otherwise, the current configuration applies only until the system reboots. When IPQoS works correctly on a system, do the following to make the configuration persistent across reboots.

  1. Test for the existence of an IPQoS configuration in the kernel modules.
    # ipqosconf -l

    If a configuration already exists, ipqosconf displays the configuration on the screen. 

  2. Ensure that the existing IPQoS configuration is applied every time the IPQoS system reboots.
    # /usr/sbin/ipqosconf -c

    The -c option causes the current IPQoS configuration to be represented in the boot-time configuration file /etc/inet/ipqosinit.conf.
