Load Sharing Guidelines

For ExtremeXOS standalone switches and SummitStacks the following rules apply to load sharing.

A static LAG (Link Aggregation Group) can contain up to eight ports.
An LACP LAG can contain twice the number of ports as a static LAG. The maximum number of selected links is the same as the limit for a static LAG. The remaining links are standby links.
A Health Check LAG can contain the same number of ports as a static LAG.
You can configure only the address-based load-sharing algorithm as described in the following sections:
- Address-Based Load Sharing
- Link Aggregation Standard and Custom Algorithms
The maximum number of LAGs for ExtremeSwitching and Summit series switches is 128.

Note

See Configuring LACP for the maximum number of links, selected and standby, per LACP.

Guidelines for the ExtremeSwitching and Summit X460-G2, X670-G2, X770, X450-G2, X590, X870, X690, Series Switches

For the ExtremeSwitching and Summit X450-G2, X460-G2, X670-G2, X770, X590, X870, X690, series switches, the following rules apply to load sharing.

A static LAG can contain up to 32 ports when configured to use the L2,L3,L3_L4 or custom algorithm.
For all the algorithms, LACP LAG can contain up to 64 ports per LAG, which includes up to 32 selected links and 32 standby links.
A SummitStack consisting entirely of X450-G2, X460-G2, X590, X670-G2, X770, X870, and X690 switches can contain up to 64 ports for all algorithms. All platforms have the same stacking limits.
