Hierarchy Level


Disable distributed periodic packet management (PPM) processing and run all PPM processing on the Routing Engine.

PPM processing cannot be completely disabled on EX Series switches. You can only configure whether PPM processing is distributed between the access ports (EX3200 and EX4200 switches) or the line cards (EX8200 switches) and the Routing Engine or is handled just on the Routing Engine.

Best Practice:

Generally, you should only disable distributed PPM if Juniper Networks Customer Service advised you to do so. You should only disable distributed PPM if you have a compelling reason to disable it.


Distributed PPM processing is enabled.
