Description

(MX Series routers with MPC line cards only) To enable the inline Link Aggregation Control Protocol (LACP) PDU transmission processing.

This statement disables the default distributed periodic packet management (PPM) processing for Link Aggregation Control Protocol (LACP) packets and run all Link Aggregation Control Protocol (LACP) PDU transmission processing inline. The inline option can be used in scenarios where the line card CPU is under heavy load and cannot schedule the PPM processing for LACP packets. PPM, by default, delegates the transmission of PDUs to the PPMAN process on the PFE/line card. But when the inline option is configured, it delegates the transmission of LCAP PDUs even further away from the line card CPU and into the forwarding chipset.

For example, in a system with both MPCs and DPCs, upon configuration of [protocols lacp ppm inline], the PDUs are sent inline on the MPCs and performed by periodic packet management (PPM) on DPCs.

Best Practice:

We recommend to retain the default and disable distributed PPM or enable inline processing only if Juniper Networks Customer Service advises you to do so. You should disable distributed PPM or enable inline processing only if you have a compelling reason to disable it.

Refer Disabling or Enabling Inline Periodic Packet Management for LACP Packets for more details.

Default

Distributed PPM processing is enabled for all packets that use PPM.
