Configuring Tracking Plug-Ins
This section shows how to configure the tracking plug-ins described in Table 16.
By default, the fileAcct plug-in instance tracks all subscriber and service sessions and writes all available attributes to a file. You can use this plug-in instance or create new one.
Configuring Flat File Accounting Plug-Ins
Flat file accounting plug-ins write information to a file in a comma-separated format. The SRC software has a default flat file accounting plug-in instance called fileAcct. The fileAcct instance logs all possible attributes for 24-hour periods in the file var/acct/log.
Another item that you can configure for flat files is the names of the headers that appear in the file. See Configuring Headers for Flat File Accounting Plug-Ins.
Use the following configuration statements to create flat-file accounting plug-in instances:
shared sae configuration plug-ins namename
file-accounting {filenamefilename
;templatetemplate
;intervalinterval
;fields [(status | nas-id | host | router-name | interface-name | interface-alias | interface-descr | port-id | user-ip-address | login-name | accounting-id | auth-user-id | if-radius-class | if-session-id | service-name | radius-class | event-time | session-id | terminate-cause | session-time | in-octets | out-octets | in-packets | out-packets | nas-ip | user-mac-address | service-session-name | service-session-tag | user-type | user-radius-class | user-session-id | primary-user-name | subscription-name | login-id | if-index | event-time-millisecond | nas-port | operational | user-inet-address | nas-inet-address | router-type | interface-speed)...];}To create flat-file accounting plug-ins:
- From configuration mode, access the basic RADIUS accounting plug-in configuration. In this sample procedure, the plug-in called fileAcct is configured in the west-region SAE group.
user@host#edit shared sae group west-region configuration plug-ins name fileAcct file-accounting

Configuring Headers for Flat File Accounting Plug-Ins
When the SAE writes data to a flat file, it writes into the first line the headers that identify the attributes in the file. For example, in the following accounting file, the first line lists headers for all attribute fields in the file, and the following lines list the actual data in each field:
Accounting Status,NAS ID,SSP Host,Router Name,Interface Name,Interface Alias,Interface Description,NAS port ID,User IP Address,User ID,User Accounting ID,User Authentication ID,INTF Radius Class,INTF,SessionId, Service Name,Radius Class,Timestamp,SessionId, Terminate Cause,Session Time,Input Octets,Output Octets,Input Packets,Output Packets,NAS IP,User Mac address,Service Session Name,Service Session Tag,User Session Type,User Session Radius Class,User Session IDstart,SSP.uelmo,uelmo,default@erx7_ssp57,FastEthernet1/1.1,,IP1/1.1,default@erx7 _ssp57 FastEthernet1/1:65535, 10.10.10.20,pebbles@virneo.net,,,,erx fastEthernet 1/1:0001048619,Video-Gold,Video-Gold,Fri Jan 30 14:23:29 EDT 2004, VideoGold:null:1064946209182, 0,0,0,0,0,0, 10.10.7.17,,,,PPP,, pebbles:1064946144841You can assign your own names to the headers that appear in the file. To do so, define the header names in a template, and then set up file accounting plug-in instances to use the template. The default template, FileAccounting.std, defines header names for all possible attributes. You can use the default template or create your own templates.
Use the following configuration statements to create a file accounting template:
shared sae configuration file-accounting-templatename
...shared sae configuration file-accounting-templatename
attributes (status | nas-id | host | router-name | interface-name | interface-alias | interface-descr | port-id | user-ip-address | login-name | accounting-id | auth-user-id | if-radius-class | if-session-id | service-name | radius-class | event-time | session-id | terminate-cause | session-time | in-octets | out-octets | in-packets | out-packets | nas-ip | user-mac-address | service-session-name | service-session-tag | user-type | user-radius-class | user-session-id | primary-user-name | subscription-name | login-id | if-index | event-time-millisecond | nas-port | operational | user-inet-address | nas-inet-address | router-type | interface-speed | service-bundle | user-dn | uid | domain | retailer-dn | password | service-scope | session-timeout | downstream-bandwidth | upstream-bandwidth | dhcp-packet | aggr-session-id | aggr-login-name | aggr-user-dn | aggr-user-inet-address | aggr-accounting-id | aggr-auth-user-id) {value
;}To set up a file accounting template:
- From configuration mode, access the file accounting template configuration. In this sample procedure, the template called std is configured in the west-region SAE group.
user@host#edit shared sae group west-region configuration file-accounting-template std
- Define header names.
[edit shared sae group west-region configuration file-accounting-template std]user@host#set attributes

You can use basic RADIUS accounting plug-ins to send accounting information to an external RADIUS accounting server or to a group of redundant servers. To communicate with nonredundant servers, you need to create multiple instances of the plug-in.
Use the following configuration statements to configure RADIUS accounting plug-ins:
shared sae configuration plug-ins namename
radius-accounting {load-balancing-mode (failover | roundRobin); failback-timerfailback-timer
; nas-ip (SspIp | ErxIp); retry-intervalretry-interval

Configuring Flexible RADIUS Accounting Plug-Ins
Flexible RADIUS accounting plug-ins provide the same features as basic RADIUS accounting plug-ins. In addition, they allow you to customize RADIUS accounting packets that the SAE sends to RADIUS servers. You can specify which fields are included in the RADIUS accounting packets and what information is contained in the fields.
Use the following configuration statements to configure flexible RADIUS accounting plug-ins:
shared sae configuration plug-ins namename
flex-radius-accounting {load-balancing-mode (failover | roundRobin); failback-timerfailback-timer

Configuring Custom RADIUS Accounting-Plug-Ins
The custom RADIUS accounting plug-ins provide the same functions as the flexible RADIUS accounting plug-ins, but are designed to deliver better system performance. To use a custom plug-in, you must provide a Java class that implements the service provider interface (SPI) defined in the RADIUS client library. Use this SPI to specify which fields and field values to include in RADIUS accounting packets. The RADIUS client library is part of the SAE core application programming interface (API).
See the documentation for the RADIUS client library in the SRC software distribution in the folder SDK/doc/sae/net/juniper/smgt/sae/radiuslib or in the SAE core API documentation on the Juniper Networks Web site at
http://www.juniper.net/techpubs/software/management/sdx/api-index.html
For a sample implementation, see the following directory in the SRC software distribution:
SDK/plugin/java/src/net/juniper/smgt/sample/radiuslib/RadiusPacketHandlerImpl.java.
Use the following configuration statements to set up custom RADIUS accounting plug-ins:
shared sae configuration plug-ins namename
custom-radius-accounting {java-class-radius-packet-handlerjava-class-radius-packet-handler
; class-path-radius-packet-handlerclass-path-radius-packet-handler
