Configuring L-PDF Profiles

[ Contents] [ Prev] [ Next] [ Index] [ Report an Error]

The local policy decision function (L-PDF) enables you to configure properties for statistics output. To do this, you create a policy decision statistics profile, which configures the files to which statistics records are exported and the format that is exported. You specify the profile by including the following configuration at the [edit accounting-options] hierarchy level:


            
               [edit accounting-options]
               policy-decision-statistics-profile profile-name {
               
               aacl-fields [ field-name ];
               
               file filename;
               
               files file-number;
               
               size bytes;
               
               }

You specify a profile name to identify the profile and other properties as needed. The aacl-fields statement specifies which statistics to collect in an accounting-data log file. This log file is located on the /var/log directory on the router. You specify the log file by including the file filename statement. The filename is prefixed by the aacl_statistics_ prefix; for example, if you specify the filename lpdfd, the log file will be /var/log/aacl_statistics_lpdfd.

The aacl-fields statement supports the following options:

address—IP Address
application—Application name
application-group—Application group name
input-bytes—Number of input bytes
input-interface—Input interface name
input-packets—Number of input packets
mask—Netmask
output-bytes—Number of output bytes
output-packets—Number of output packets
subscriber-name—Subscriber name
timestamp—Timestamp
vrf-name—VPN routing and forwarding (VRF) name
