Release Information Statement introduced in Junos OS Release 9.4.
Statement introduced in Junos OS Release 10.2 for EX Series switches.
Statement introduced in Junos OS Release 11.3 for the QFX Series.
Statement introduced in Junos OS Release 12.3 for ACX Series routers.
Statement introduced in Junos OS Release 14.1X53-D20 for the OCX Series.
Description (M120, M320, MX Series, T Series, TX Matrix routers, M7i and M10i routers with Enhanced
CFEB [CFEB-E], EX Series switches, and QFX Series only) Disable distributed periodic
packet management (PPM) to the Packet Forwarding Engine (on routers), to access
ports (on EX3200 and EX4200 switches, and QFX Series), or to line cards (on EX6200
and EX8200 switches).
After you disable PPM, PPM processing continues to run on the Routing Engine.
In Junos OS Release 8.2, PPM was moved from the Routing Engine to the Packet
Forwarding Engine, access ports, or line cards. The no-delegate-processing statement
disables the default behavior and restores the legacy behavior.
Default Distributed PPM processing is enabled for all protocols that use PPM such as:
• Bidirectional Forwarding Detection (BFD)
• Connectivity Fault Management (CFM)
• Link Aggregation Control Protocol (LACP)
• Link Fault Management (LFM)
• Multiprotocol Label Switching (MPLS)
• Real-time Performance Monitoring (RPM)
• Spanning Tree Protocol (STP)
• Synchronous Ethernet (SYNCE)
• Virtual Router Redundancy Protocol (VRRP)
Options no-delegate-processing—Disable PPM to the Packet Forwarding Engine, access ports, or
line cards. Distributed PPM is enabled by default.
