Load-Sharing Algorithms

Load-sharing, or link aggregation, algorithms select an egress link for each packet forwarded to egress the LAG.

The ExtremeXOS software supports the following types of load sharing algorithms:
  • Address based—The egress link is chosen based on packet contents.
  • Port-based—The egress link is chosen based on the key assigned to the ingress port.

The ExtremeXOS software provides multiple addressed-based algorithms. For some types of traffic, the algorithm is fixed and cannot be changed. For other types of traffic, you can configure an algorithm. Algorithm selection is not intended for use in predictive traffic engineering.

The following sections describe the algorithm choices for different platforms:

Note

Always reference the master logical port of the load-sharing group when configuring or viewing VLANs. VLANs configured to use other ports in the LAG will have those ports deleted from the VLAN when link aggregation is enabled.
