Logically, the configuration diagram would be the same as in the previous case, since both switches are considered a single logical switch. However, the switch is no longer a SPOF (Single Point Of Failure).
The following physical configuration diagram will therefore enable full fault tolerance:
Two Stormshield Network firewalls form a high availability cluster with an active node and a passive node.
Each node in the cluster is linked to two separate switches through link aggregation.
Both switches are stackable. Depending on brands and models, there may be an active switch and a passive switch, or both switches may be in active mode. Switches make it possible to spread out aggregates as two aggregated interfaces can be spread out over two physical switches.
