Applying an IPQoS Configuration

You activate and otherwise manipulate the IPQoS configuration by using the ipqosconf command.

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, which is created in Creating IPQoS Configuration Files for Web Servers. For detailed information, refer to the ipqosconf(1M) man page.

Assume the Primary Administrator role, or become superuser, on the IPQoS-enabled system.
The Primary Administrator role includes the Primary Administrator profile. To create the role and assign the role to a user, see Chapter 2, Working With the Solaris Management Console (Tasks), in System Administration Guide: Basic Administration.
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 Solaris kernel. In this example, the contents of /var/ipqos/Goldweb.qos are applied to the current 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.
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.

Assume the Primary Administrator role, or become superuser, on the IPQoS-enabled system.
The Primary Administrator role includes the Primary Administrator profile. To create the role and assign the role to a user, see Chapter 2, Working With the Solaris Management Console (Tasks), in System Administration Guide: Basic Administration.
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. If you do not receive output, apply the configuration, as explained in How to Apply a New Configuration to the IPQoS Kernel Modules.
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.
