RT-5.10: LACP Intervals

Summary

Validate link operational status of LACP LAG and also validate lacp timers

Procedure

  • Connect DUT-1 ports 1-4 to DUT-2 ports 1-4, Configure both DUTs ports 1-4 to be part of a LAG.

  • With LACP:

    • Ensure that LAG is successfully negotiated, verifying port status for each of DUT ports 1-4 reflects expected LAG state via DUT telemetry.
    • Verify LACP LAG intervals with period type SLOW and FAST
