To avoid split-brain scenarios in VSF stacks, the VSL split-detect mgrep command is used to enable multicast group detection over the Virtual Switching Link (VSL). This helps detect when the stack links are down or partitioned, triggering appropriate failover or shutdown mechanisms.
Options like vsf start-auto-stacking, vsf secondary-member 2, or vsf conductor-member 2 are related to stack initialization and member roles but do not address split-brain detection directly.
Hence, enabling split-detect with mgrep is the best practice for VSF stack stability.
