How to Enable Accounting for a Class in the IPQoS Configuration File

This procedure shows how to enable accounting on a traffic class in the IPQoS configuration file. It defines flow accounting for the video class, which is introduced in How to Create the IPQoS Configuration File and Define Traffic Classes. This class selects streaming video traffic, which must be billed as part of a premium customer's SLA.

Before You Begin

The procedure assumes that you have an existing IPQoS configuration file with defined classes, filters, metering actions, if appropriate, and marking actions, if appropriate. It continues building the IPQOS configuration file from Example 3–1.

1. Become an administrator.

   For more information, see Using Your Assigned Administrative Rights in Securing Users and Processes in Oracle Solaris 11.2 .

2. If the IPQoS configuration file is not already open, open it.
3. Locate the end of the last action statement you defined.

   For example, on the IPQoS-enabled server Goldweb, you would start after the following markEF action statement in the configuration file, /etc/inet/ipqosinit.conf.

   action {
       module dscpmk
       name markEF
       params {
           global_stats TRUE
           dscp_map{0-63:46}
           next_action acct
       }
   }

4. Begin an action statement that calls flow accounting.

   action {
       module flowacct
       name acct

   module flowacct

   Invokes the flow-accounting module flowacct.

   name acct

   Assigns the name acct to the action statement

5. Define a params clause to control accounting on the traffic class.

   params {
           global_stats TRUE
           timer 10000
           timeout 10000
           max_limit 2048
           next_action continue
       }
   }

   global_stats TRUE

   Enables statistics collection on the class video, which selects streaming video packets.

   timer 10000

   Specifies the duration of the interval, in milliseconds, when the flow table is scanned for timed-out flows. In this parameter, that interval is 10000 milliseconds.

   timeout 10000

   Specifies the minimum interval timeout value. A flow “times out” when packets for the flow are not seen during a timeout interval. In this parameter, packets time out after 10000 milliseconds.

   max_limit 2048

   Sets the maximum number of active flow records in the flow table for this action instance.

   next_action continue

   Indicates that no further processing is required on packets of the traffic class video, and that these packets can return to the network stream.

   The flowacct module gathers statistical information on packet flows of a particular class until a specified timeout value is reached.

6. 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.
