How to Configure the IPQoS Configuration File for an Application Server

Language:

Become an administrator.
For more information, see Using Your Assigned Administrative Rights in Securing Users and Processes in Oracle Solaris 11.3.

Log in to the IPQoS-enabled application server.
Create a new IPQoS configuration file with a .qos extension.
Insert the following required phrases to start the action statement that invokes the ipgpc classifier:
```
fmt_version 1.0

action {
    module ipgpc
    name ipgpc.classify
    params {
        global_stats TRUE
    }
```
For an explanation of the opening action statement, refer to How to Create the IPQoS Configuration File and Define Traffic Classes.

Add class definitions to select traffic from three applications on the BigAPPS server.
```
    class {
        name smtp
        enable_stats FALSE
        next_action markAF13
    }
    class {
        name news
        next_action markAF21
    }
    class {
        name ftp
        enable_stats TRUE
        next_action meterftp
    }
```
name smtp
Creates a class called smtp that includes email traffic flows to be handled by the SMTP application

enable_stats FALSE
Enables statistics collection for the smtp class. However, because the value of enable_stats is FALSE, statistics for this class are not taken.

next_action markAF13
Instructs the ipgpc module to pass packets of the smtp class to the markAF13 action statement after ipgpc completes processing.

name news
Creates a class called news that includes network news traffic flows to be handled by the NNTP application.

next_action markAF21
Instructs the ipgpc module to pass packets of the news class to the markAF21 action statement after ipgpc completes processing.

name ftp
Creates a class called ftp that handles outgoing traffic that is handled by the FTP application.

enable_stats TRUE
Enables statistics collection for the ftp class.

next_action meterftp
Instructs the ipgpc module to pass packets of the ftp class to the meterftp action statement after ipgpc completes processing.

For more information about defining classes, refer to How to Create the IPQoS Configuration File and Define Traffic Classes.

Define filter clauses to select traffic of the classes defined in Step 2.
```
    filter {
        name smtpout
        sport smtp
        class smtp
    }
    filter {
        name newsout
        sport nntp
        class news
    }
        filter {
        name ftpout
        sport ftp
        class ftp
    }
        filter {
        name ftpdata
        sport ftp-data
        class ftp
    }
}
```
name smtpout
Assigns the name smtpout to the filter.

sport smtp
Selects traffic with a source port of 25, the usual port for the sendmail (SMTP) application.

class smtp
Identifies the class to which the filter belongs, in this instance, class smtp.

name newsout
Assigns the name newsout to the filter.

sport nntp
Selects traffic with a source port name of nntp, the usual port name for the network news (NNTP) application.

class news
Identifies the class to which the filter belongs, in this instance, class news.

name ftpout
Assigns the name ftpout to the filter.

sport ftp
Selects control data with a source port of 21, the usual port number for FTP traffic.

name ftpdata
Assigns the name ftpdata to the filter.

sport ftp-data
Selects traffic with a source port of 20, the usual port number for FTP data traffic.

class ftp
Identifies the class to which the ftpout and ftpdata filters belong, in this instance ftp.
Save changes to the /etc/inet/ipqosinit.conf file.
- If you are done making changes, start the ipqos service.
  See How to Start the ipqos Service for specific instructions about starting or restarting the service.
- If you want to continue making changes in the IPQoS configuration file, choose another task.
  See General IPQoS Configuration Planning Task Map for a list of additional changes that might be needed.
