When creating sub interface on AR46 router, the packet counters on sub interface is the same as the main interface. customer have NMS and wants to monitor the different subinterface traffic, they hope the different subinterface can monitor their own traffic.
1.input enable ip statistics command on subinterface and main interface but it's not solved the problem.
2.check the vrp version is AR46-40 8040V300R003B03D040SP19 by change the VRP version to vrp3.4R0201p01 it's support caculate the traffic independently on subinterface.
there are 2 reason for this issue
1. enable ip statistics on interface and subinterface .
2. check the VRP version to support IP accounting or not.
