RT-5.3: Aggregate Balancing

Summary

Load balancing across members of a LACP-controlled LAG

Procedure

• Connect ATE port-1 to DUT port-1, and ATE ports 2 through 9 to DUT ports 2-9. Configure ATE and DUT ports 2-9 to be part of a LACP-controlled LAG.
• Send flows between ATE port-1 targeted towards the LAG consisting of ATE ports 2-9. Ensure that traffic is balanced across the LAG members with:
  • TODO (TCP header): IPv4 packets with varying TCP source ports.
  • TODO (TCP header): IPv6 packets with varying TCP source ports.
  • IPv6 packets with varying flow labels.
  • TODO (TCP header): IPinIP containing IPv4 payload with varying TCP source ports.
  • TODO (TCP header): IPinIP containing IPv6 payload with varying TCP source port.
  • TODO: IPinIP containing IPv6 payload with varying flow labels.
