Release Information

Statement introduced in JUNOS Release 9.3.

The ppm (centralized | distributed) option introduced in JUNOS Release 9.4.


For aggregated Ethernet interfaces only, configure the Link Aggregation Control Protocol (LACP).

On MX Series routers you can specify distributed or centralized periodic packet management (PPM).


If you do not specify lacp as either active or passive, LACP remains passive.

If you do not specify ppm as either centralized or distributed, PPM will be distributed.


  • active—Initiate transmission of LACP packets.
  • passive—Respond to LACP packets.
  • ppm—Set PPM to centralized or distributed.

The remaining statements are explained separately.
