Authentication success is not the same as authorization; WLAN roles and VLAN selection determine where the user can forward traffic. The indicated result—the authenticated test client receives the expected role or VLAN and reaches only approved application destinations—checks a different mechanism and would not confirm the required dynamic role enforcement outcome.

This would validate LACP bundled links, not dynamic role enforcement. Aggregated links require compatible control and interface parameters; mismatched LACP or VLAN settings can prevent members from joining. It is therefore insufficient acceptance evidence for the reported condition.

That result—AP status confirms full required power mode and negotiated uplink speed without feature restrictions—concerns AP uplink power and negotiation. Wireless features depend on the wired uplink and power available to the AP; sufficient coverage does not prove the device is operating at full capacity. It can be healthy even while the current dynamic role enforcement problem remains.

That result—The user subnet remains advertised by the routing process while no neighbor adjacency forms on the protected access VLAN—concerns OSPF passive interfaces. A passive interface can advertise its connected prefix through the process while avoiding unwanted OSPF hello exchanges toward endpoints. It can be healthy even while the current default-route propagation problem remains.

Gateway responsibilities such as tunnel termination and role enforcement depend on the chosen software architecture and supported role. The indicated result—the managed gateway appears under the correct role and forwards sample SSID traffic according to the intended design—checks a different mechanism and would not confirm the required default-route propagation outcome.

This would validate VRRP gateway resilience, not default-route propagation. A virtual first-hop gateway provides a stable client next-hop while authorized peers coordinate active forwarding after failure. It is therefore insufficient acceptance evidence for the reported condition.

That action—Break high-risk campus migration into staged, independently validated change waves—is relevant to change-risk classification. Changing many dependent control planes at once obscures root causes and enlarges outage blast radius; staging supplies evidence and rollback points. It does not correct the observed poE budget planning condition.

The low-level design should express observable outcomes such as authentication success, endpoint reachability, failover behavior and performance thresholds rather than only equipment names. Translate business requirements into measurable network acceptance criteria before selecting configurations. would address campus requirements and acceptance criteria, but the reported facts instead point to poE budget planning. That change would leave the actual requirement unresolved.

The alternative targets inventory and dependency discovery, where missing uplink, power, VLAN, routing and identity dependencies cause apparently successful device replacements to disconnect applications or clients unexpectedly. It does not establish the intended poE budget planning behavior described in the scenario.

The alternative targets VSX peer synchronization, where VSX peers retain independent control planes and only designated supported feature sets synchronize; unchecked settings may diverge. It does not establish the intended route redistribution filters behavior described in the scenario.

That action—Design and verify independent VSX peer keepalive connectivity relative to the inter-switch link—is relevant to VSX keepalive isolation. Separate failure detection helps peers distinguish link disruption from peer loss, reducing the risk of harmful split-brain behavior. It does not correct the observed route redistribution filters condition.

Client frames received untagged are placed in the port's access VLAN; a healthy physical link cannot compensate for wrong Layer 2 membership. Assign the correct access VLAN and verify the port's effective untagged membership. would address access port VLAN membership, but the reported facts instead point to route redistribution filters. That change would leave the actual requirement unresolved.

The alternative targets campus requirements and acceptance criteria, where the low-level design should express observable outcomes such as authentication success, endpoint reachability, failover behavior and performance thresholds rather than only equipment names. It does not establish the intended peak WLAN concurrency behavior described in the scenario.

That action—Assign clear access, aggregation and routing roles and validate their traffic and scale requirements—is relevant to access/distribution hierarchy. A functional hierarchy clarifies where endpoints attach, where traffic aggregates and where policy or Layer 3 boundaries belong. It does not correct the observed peak WLAN concurrency condition.

Real-time applications can fail with adequate average throughput when contention increases delay or jitter; requirement gathering must distinguish traffic classes. Capture application latency, jitter, loss and priority requirements as distinct design constraints. would address critical application traffic profile, but the reported facts instead point to peak WLAN concurrency. That change would leave the actual requirement unresolved.

That action—Deploy supported Network Analytics Engine agents with event conditions and response actions—is relevant to NAE event rules on AOS-CX. AOS-CX NAE provides locally evaluated telemetry/event logic; defining useful triggers matters more than merely enabling generic monitoring. It does not correct the observed syslog event centralization condition.

Dependency-aware grouping prevents alert floods from hiding the primary failure and makes operational response more focused. Correlate related monitoring events and route prioritized alerts to appropriate responders. would address alert correlation and noise reduction, but the reported facts instead point to syslog event centralization. That change would leave the actual requirement unresolved.

The alternative targets AAA change coordination, where identity changes impact access before network routing tests can begin; testing distinct client classes limits unintended lockouts. It does not establish the intended syslog event centralization behavior described in the scenario.

This would validate security-preserving optimization, not client experience versus device uptime. A performance gain is not acceptable if it weakens required access boundaries; improvements must meet both service and security acceptance criteria. It is therefore insufficient acceptance evidence for the reported condition.

Downlink strength from a powerful AP does not increase client transmit capability; asymmetric links and oversized cells can harm roaming. The indicated result—client RSSI, uplink quality and roaming measurements improve without creating coverage gaps—checks a different mechanism and would not confirm the required client experience versus device uptime outcome.

That result—Consumption and service-quality metrics improve outside peak hours without violating coverage or capacity objectives—concerns energy and utilization efficiency. Right-sized operation reduces unnecessary resource use, but energy or capacity savings must not remove availability when users actually need the network. It can be healthy even while the current client experience versus device uptime problem remains.

A performance gain is not acceptable if it weakens required access boundaries; improvements must meet both service and security acceptance criteria. The indicated result—post-change tests show better permitted-traffic performance and unchanged denial of prohibited flows—checks a different mechanism and would not confirm the required failure recovery time objective outcome.

This would validate legacy low-rate airtime overhead, not failure recovery time objective. Low PHY data rates use more airtime per transmitted bit; rate changes must be constrained by coverage and device support. It is therefore insufficient acceptance evidence for the reported condition.

That result—Synthetic or real-user results show acceptable authentication, address acquisition, DNS and application response at representative sites—concerns client experience versus device uptime. Infrastructure availability is necessary but not sufficient for usable service; end-to-end user journeys expose service dependencies beyond device health. It can be healthy even while the current failure recovery time objective problem remains.

That result—Both ends of the link agree on intended tagged and untagged handling and the untagged test frame enters only the approved VLAN—concerns native VLAN alignment. When connected trunk ports disagree about how untagged frames are classified, management and user traffic can land in unintended segments. It can be healthy even while the current static route and next-hop reachability problem remains.

This would validate classic Central site versus group, not static route and next-hop reachability. Classic Central uses groups to distribute shared configuration while sites provide physical-location organization, so modifying location alone need not change running intent. It is therefore insufficient acceptance evidence for the reported condition.

A VLAN's existence on each switch is insufficient if the inter-switch trunk omits it, so frames cannot traverse the missing membership. The indicated result—the VLAN is present on each relevant trunk and authenticated client traffic traverses the expected path—checks a different mechanism and would not confirm the required static route and next-hop reachability outcome.

That result—Spectrum observations isolate the interference source and the post-remediation error rate falls measurably—concerns interference spectrum diagnosis. Non-802.11 emitters can occupy channel energy without appearing as normal Wi-Fi neighbors; channel changes or source mitigation need measured evidence. It can be healthy even while the current client experience versus device uptime problem remains.

Resilience depends on recovery behavior, routing/bridging convergence and application tolerance, not the number of installed redundant devices. The indicated result—a forced component failure restores approved traffic within a measured recovery-time objective—checks a different mechanism and would not confirm the required client experience versus device uptime outcome.

This would validate periodic baseline refresh, not client experience versus device uptime. A fixed historical baseline can become misleading as workload mix and client capability change; thresholds should reflect current accepted operating conditions. It is therefore insufficient acceptance evidence for the reported condition.

That action—Inspect New Central scope inheritance and device-level precedence before changing shared policy—is relevant to new Central scoped inheritance. New Central includes global, collection, site and device scopes; more specific applicable configuration can override broader inherited values. It does not correct the observed VSF member management condition.

A passive interface can advertise its connected prefix through the process while avoiding unwanted OSPF hello exchanges toward endpoints. Use OSPF passive-interface behavior on endpoint-facing networks that need no routing neighbors. would address OSPF passive interfaces, but the reported facts instead point to VSF member management. That change would leave the actual requirement unresolved.

The alternative targets default-route propagation, where a routing protocol's internal adjacency does not guarantee a usable route for unknown destinations; a valid and authorized default egress is needed. It does not establish the intended VSF member management behavior described in the scenario.
