[j-nsp] packet sampling does not export any data, why?

[Vadim Shesterin]

Hi, Joe,

You need define service accounting interface in forwarding options.
For example:

sampling {
     input {
         family inet {
             rate 1;
         }
     }
     output {
         cflowd XX.XX.XX.XX {
             port xxxx;
             version 5;
             no-local-dump;
         }
         flow-inactive-timeout 15;
         flow-active-timeout 60;
         interface sp-0/3/0 {
             engine-id 0;
             engine-type 1;
             source-address ZZ.ZZ.ZZ.ZZ;
         }
     }
}

Also you can check AS-PIC work by using command:

 > show services accounting flow
 > show services accounting errors
