Explanation

The ISL and keepalive goes down, and after a few seconds, the keepalive link restores. Switch-1 and Switch-2 remains up. The Split-recovery mode is enabled. In this case the secondary switch shutdowns SVIs when keepalive is restored is a correct description of how the Virtual Switching Extension (VSX) fabric reacts to various component failure scenarios. VSX is a feature that provides active-active forwarding and redundancy for ArubaOS-CX switches. The ISL is the inter- switch link that connects two VSX nodes and carries data traffic. The keepalive link is a separate link that carries control traffic between two VSX nodes. The split-recovery mode is a feature that prevents split-brain scenarios when both VSX nodes lose connectivity with each other but remain up. When the ISL and keepalive goes down, both VSX nodes continue to forward traffic independently. When the keepalive link restores, the secondary switch detects that it has lost synchronization with the primary switch and shuts down its SVIs to prevent traffic loops.
