RT-5.2: Aggregate Interfaces

Canonical OC

{}

Summary

Validate link operational status of Static LAG and LACP.

Procedure

  • Connect ATE port-1 to DUT port-1, and ATE ports 2 through 8 to DUT ports 2-8. Configure ATE and DUT ports 2-8 to be part of a LAG.
  • For both static LAG and LACP:
    • Ensure that LAG is successfully negotiated, verifying port status for each of DUT ports 2-8 reflects expected LAG state via ATE and DUT telemetry.
    • Ensure that configuring a minimum links setting for the LAG the entire interface is marked:
      • Down when min-1 links are up
      • Up when min links are up
      • Up when >min links are up.
    • TODO: Verify the above by sending flows between ATE port-1 targeted towards the LAG.
