Is this a use case for disabling split-recovery mode on ArubaOS-CX switches in a Virtual Switching

Extension (VSX) fabric?

Solution: In situations in which the primary switch fails and then reboots, you want to make the primary switch take over again as the primary switch.

Suggested answer: B

Explanation:

Virtual Switching Extension (VSX) is a high-availability technology that allows two ArubaOS-CX switches to operate as a single logical device. Split-recovery mode is a feature that prevents traffic loss when the Inter-Switch Link (ISL) goes out-of-sync and keepalive subsequently fails. When splitrecovery mode is enabled, the secondary VSX member disables its downstream links until it synchronizes with the primary member. When split-recovery mode is disabled, the secondary VSX member keeps its downstream links up even when it is out-of-sync with the primary member1. Disabling split-recovery mode does not affect how the primary switch takes over again as the primary switch after a failure and reboot. The primary switch always takes over as the primary switch when it comes back online, regardless of the split-recovery mode setting. Therefore, this is not a use case for disabling split-recovery mode on ArubaOS-CX switches in a VSX fabric.
