At a design studio in Berlin, the observation may be useful for a separate Multi-chassis LAGs and active paths test, but it does not establish that operators assume the VSX ISL is unnecessary because both chassis are individually reachable has been resolved. The relevant check is the VSX inter-switch link and keepalive outcome.

At a design studio in Berlin, this would verify First-hop gateway redundancy and failover, not the failure reported in this scenario. The requested closure criterion instead concerns VSX inter-switch link and keepalive: the VSX peers show intended primary/secondary state with healthy ISL and keepalive, and a fault test preserves eligible forwarding.

At a design studio in Berlin, the observation may be useful for a separate VSF member roles and stack consistency test, but it does not establish that operators assume the VSX ISL is unnecessary because both chassis are individually reachable has been resolved. The relevant check is the VSX inter-switch link and keepalive outcome.

Although this is a valid design approach for VSF member roles and stack consistency in an appropriate case, it leaves the VSX inter-switch link and keepalive dependency untested. The observed condition at a university faculty building in Boston is that operators assume the VSX ISL is unnecessary because both chassis are individually reachable.

At a university faculty building in Boston, the option addresses First-hop gateway redundancy and failover rather than the reported issue. For the stated symptom, the expected evidence is that the VSX peers show intended primary/secondary state with healthy ISL and keepalive, and a fault test preserves eligible forwarding.

At a university faculty building in Boston, that change is aimed at Multi-chassis LAGs and active paths, not at the actual fault: operators assume the VSX ISL is unnecessary because both chassis are individually reachable. A successful repair here must show that the VSX peers show intended primary/secondary state with healthy ISL and keepalive, and a fault test preserves eligible forwarding.

At a university faculty building in Boston, this measures a different network requirement, First-hop gateway redundancy and failover. The case describes that operators assume the VSX ISL is unnecessary because both chassis are individually reachable, so accepting this result would leave the primary fault without direct verification.

At a utility control office in Raleigh, the option addresses VSF member roles and stack consistency rather than the reported issue. For the stated symptom, the expected evidence is that the VSX peers show intended primary/secondary state with healthy ISL and keepalive, and a fault test preserves eligible forwarding.

At a utility control office in Raleigh, that change is aimed at Multi-chassis LAGs and active paths, not at the actual fault: an ISL cable fails and engineers cannot distinguish a peer outage from an interconnect failure. A successful repair here must show that the VSX peers show intended primary/secondary state with healthy ISL and keepalive, and a fault test preserves eligible forwarding.

At an engineering school in Copenhagen, the option addresses First-hop gateway redundancy and failover rather than the reported issue.

At a financial services campus in Zurich, the option addresses First-hop gateway redundancy and failover rather than the reported issue. For the stated symptom, the expected evidence is that the VSX peers show intended primary/secondary state with healthy ISL and keepalive, and a fault test preserves eligible forwarding.

Although this is a valid design approach for Multi-chassis LAGs and active paths in an appropriate case, it leaves the VSX inter-switch link and keepalive dependency untested. The observed condition at a financial services campus in Zurich is that a campus distribution pair has valid downstream links but the VSX peer-status output is unhealthy.
