Cisco IOS XR ASR9000 LPTS Test

We changed the default value of LPTS for LDP traffic, then we generated LDP traffic by a network tester:

RP/0/RSP0/CPU0:ASR9010_Labrouter1#show lpts pifib hardware police location 0/0/CPU0

Then usage of CPU is increased:

RP/0/RSP0/CPU0:ASR9010#show process cpu                                 

CPU utilization for one minute: 100%; five minutes: 45%; fifteen minutes: 18%

Conclusion; Default rates of LPTS is ok, dont change them :)
