EX Series Switch Software Features Overview on page 3
Periodic packet management (PPM) is responsible for processing a variety of
time-sensitive periodic tasks for particular processes so that other processes on the
Juniper Networks EX Series Ethernet Switch can more optimally direct their resources.
PPM is responsible for the periodic transmission of packets on behalf of its various client
processes, which include the process that controls Link Aggregation Control Protocol
(LACP), and also for receiving packets on behalf of these client processes. PPM also
gathers some statistics and sends process-specific packets. PPM cannot be disabled
and is always running on any operational switch.
The responsibility for PPM processing on the switch is distributed between the Routing
Engine and either the access interfaces (on EX3200 and EX4200 switches) or the line
cards (on EX8200 switches) for all protocols that use PPM by default. This distributed
