Load balancing distribution

The following table provides details for each feature that provides load balancing.

Table 1. Load balancing algorithms

Feature

Algorithm

Port-channels

Provides adaptive load balancing based on up to seven criteria (7-tuple), depending upon what fields are available in the frame.

Trunk

Provides equal packet load balancing (round-robin) among member links.

Under multiple port-channel hops, if confronted with both underutilized and overloaded interfaces, try changing the hashing scheme on one hop to avoid such traffic polarization.
