Restore the previous stable ISL wiring and configuration before changing active-gateway behavior or reopening traffic. This instead concerns vsx inter-switch link integrity. A VSX deployment requires a healthy inter-switch link for coordinated peer functions; keepalive reachability alone does not replace it. It would not safely roll back the relevant failed change. The immediate problem concerns resilient gateway versus routing adjacency. For the incident in this item: A new branch distribution pair provides redundant physical links but its endpoint subnet has only one operative gateway address.

Reinstate the previously reachable keepalive interface and route while preserving the working ISL configuration. This instead concerns vsx keepalive versus isl failure. Keepalive and ISL supply complementary VSX control evidence; treating them as the same link obscures failure isolation. It would not safely roll back the relevant failed change. The immediate problem concerns resilient gateway versus routing adjacency. For the incident in this item: A new branch distribution pair provides redundant physical links but its endpoint subnet has only one operative gateway address.

Restore the former working stack-link connections and member addressing before proceeding with a broader stack upgrade. This instead concerns vsf member and conductor status. VSF provides a single logical switch across supported members, which differs from independent VSX peer devices and their ISL. It would not safely roll back the relevant failed change. The immediate problem concerns resilient gateway versus routing adjacency. For the incident in this item: A new branch distribution pair provides redundant physical links but its endpoint subnet has only one operative gateway address.

Inspect native VLAN settings and untagged ingress or egress classification on both connected trunk interfaces. This instead concerns native vlan mismatch.
