Load Sharing Guidelines
For ExtremeXOS standalone switches and SummitStacks the following rules apply to load sharing.
- A static LAG 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:
- The maximum number of LAGs for ExtremeSwitching series switches is 128.
Guidelines for the Switches
The following rules apply to load sharing for all Universal platforms:
- 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 5520 or 5720 switches can contain up to 64 ports for all algorithms. All platforms have the same stacking limits.
- A SummitStack consisting entirely of 5320 or 5420 switches can contain up to 8 ports for all algorithms.
