How to capture LACP frames from RE?

  • 1.  How to capture LACP frames from RE?

    Posted 03-26-2024 12:10

    Hi! Experts

    We want to  capture LACP frames to debug  LACP issue but it seems we cannot capture it from RE. 

    We have configured  "set routing-options ppm no-delegate-processing ", but it seems LACP is still processed by ppm. and there is still no packets came in "monitor traffic interface ..."

    lab@MX80# run show ppm adjacencies 
    Protocol   Hold time (msec)
    LACP       3000           
    LACP       3000           
     
    Adjacencies: 2, Remote adjacencies: 2
     
    [edit]
    lab@MX80# run show ppm adjacencies detail 
     
    Protocol: LACP, Hold time: 3000, IFL-index: 349
    Distributed: TRUE
    Distribution handle: 83, Distribution address: tfeb0
     
    Protocol: LACP, Hold time: 3000, IFL-index: 350
    Distributed: TRUE
    Distribution handle: 85, Distribution address: tfeb0
     
    Adjacencies: 2, Remote adjacencies: 2
    We have also tried it in QFX switches with same issue.
    Could you pls shed some light on this and thanks for your great help.
