Configure Accounting for the Logical Interface

Juniper Networks routers can collect various kinds of data about traffic passing through the router. You can set up one or more accounting profiles that specify some common characteristics of this data, including the following:

• The fields used in the accounting records
• The number of files that the router retains before discarding, and the number of bytes per file
• The period that the system uses to record the data

You configure the profiles and define a unique name for each profile using statements at the [edit accounting-options] hierarchy level. There are two types of accounting profiles: interface profiles and filter profiles. You configure interface profiles by including the interface-profile statement at the [edit accounting-options] hierarchy level. You configure filter profiles by including the filter-profile statement at the [edit accounting-options] hierarchy level. For more information, see the JUNOS Internet Software Configuration Guide: Network Management.

You apply filter profiles by including the accounting-profile statement at the [edit firewall filter filter-name] and [edit firewall family family filter filter-name] hierarchy levels. For more information, see the JUNOS Internet Software Configuration Guide: Policy Framework.

Apply an Accounting Profile to the Logical Interface

To enable accounting on a logical interface, include the accounting-profile statement:

accounting-profile name; 

You can configure this statement at the following hierarchy levels:

• [edit interfaces interface-name unit logical-unit-number]
• [edit logical-routers logical-router-name interfaces interface-name unit logical-unit-number]

You can also reference profiles for the physical interface; for more information, see Configure Accounting for the Physical Interface.

Example: Apply an Accounting Profile to the Logical Interface

Configure an accounting profile for an interface and apply it to a physical interface:

[edit]

accounting-options {

    file if_stats {

        size 4m files 10 transfer-interval 15;

        archive-sites {

            "ftp://login:password@host/path";

        }

    }

    interface-profile if_profile {

        interval 15;

        file if_stats {

            fields {

                input-bytes;

                output-bytes;

                input-packets;

                output-packets;

                input-errors;

                output-errors;

            }

        }

    }

}

[edit interfaces ge-1/0/1 unit 1]

accounting-profile if_profile;
