Junos OS

Hi Experts,

I would like to obtain a list of client processes that by default off loaded to ppmd (periodic packet management process daemon). I know that LACP/BFD are couple of them. Please provide full list of such processes.

Thanks in advance,

Best Regards,

Hardik

Hello,

"show ppm transmissions detail" would give this info:

Now, depending on your JUNOS version, "show ppm transmissions" command may be hidden (I did a quick check and it is unhidden in 11.4 and 12.2 - I do not have time to check all supported JUNOS versions), please type the command in full and do not use ? (question mark) for syntax help.

Thanks

Hi Alex,

I appreciate your swift respnose. It indeed helped me 🙂

Hi expert

I also used a 2 commands: 

+ show ppm adjacencies detail protocol bfd

and Junos displays the following output:

Protocol: BFD, Hold time: 540000, IFL-index: 0
Distributed: FALSE
BFD discriminator: 16, BFD routing table index: 0
HadExpired: FALSE, Expired-Count: 0, Largest-Interval: 179948, Last Rx Interval: 178309, Num Packets: 333, Absorbed Packets: 329, Rx Packet: 20 C0 03 18 00 00 00 20 00 00 00 10 0A BA 95 00 0A BA 95 00 00 00 00 00

+ show ppm adjacencies detail protocol lacp

Protocol: LACP, Hold time: 3000, IFL-index: 13908
Distributed: TRUE
Distribution handle: 382, Distribution address: fpc3

Can you explain to me what does that red word " false , true" mean? 

Hello there,

"Distributed" in this context means "runs on linecard CPUs".

Therefore, "Distributed: TRUE" means "runs on linecard CPUs", honest 

Consequently, "Distributed: FALSE" means "runs on Routing Engine CPU".

HTH

Thanks

Alex

Thanks you very much 🙂

Hi expert

When I execute this command to change from Routing engine to Packet forwarding engine:

set interface lo0 unit 0 family mpls  

It also displays BFD running on Routing engine CPU

abc@xyz# run show ppm adjacencies detail protocol bfd

Protocol: BFD, Hold time: 540000, IFL-index: 2892
Distributed: FALSE
BFD discriminator: 16, BFD routing table index: 0
HadExpired: FALSE, Expired-Count: 0, Largest-Interval: 178556, Last Rx Interval: 152429, Num Packets: 107, Absorbed Packets: 13, Rx Packet: 20 C0 03 18 00 00 C8 66 00 00 00 10 00 00 C3 50 00 00 C3 50 00 00 00 00

How can I move Distributed: FALSE to Distributed: TRUE

Please help me

Thanks
