If the ISL between two VSX core switches is down and logs indicate that Core-2 has disabled its VSX LAG interfaces, it means Core-2 has disabled its VSX LAG interfaces, likely as a protective or failover mechanism.

Keepalive packets being dropped (Option B) may cause issues but logs specifically state interface disablement.

Both switches forwarding traffic (Option C) is unlikely if ISL is down.

Downstream switches inability to forward traffic (Option D) is a consequence, not the cause.

The command erase all zeroize performs a secure erase on the switch, which deletes all customer data including startup-config and stored credentials. This process can take up to an hour depending on the hardware and storage media.

It does not retain running config (Option A).

It does not restore the factory AOS-CX image (Option B).

Admin credentials are deleted as part of the secure erase (Option C is incorrect).

Therefore, this command securely wipes all data and resets the device.

The LACP state event Actor state: ALFNCD, Partner state: ASFNCD indicates that the LACP negotiation between the local (actor) and peer (partner) is successful with all flags matching and no errors.

ALFNCD and ASFNCD are standard LACP states indicating Active, Long timeout, Aggregation capable, Not synchronized, Collecting, and Distributing flags set as expected.

Also, the log shows the LACP rate is set to slow, which is the default.

Thus, the output shows the LAG 253 has a matching LACP configuration with its peer.

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.
