Stacking LAG

When multiple links are used between stack units, FTOS automatically bundles them in a stacking LAG to

provide aggregated throughput and redundancy. The stacking LAG is established automatically and

transparently by FTOS (without user configuration) once peering is detected and behaves as follows:

The stacking LAG dynamically aggregates; it can lose link members or gain new links.

Shortest path selection inside the stack: If multiple paths exist between two units in the stack, the

shortest path is used.

The S4810 supports stacking in a ring or a daisy chain topology. Dell Force10 recommends the ring

topology when stacking S4810 switches to provide redundant connectivity.
