That result—The approved compatibility matrix and staged test confirm dependent components function on the selected release set—concerns firmware compatibility dependency. Release-specific feature and compatibility constraints can break management or forwarding despite a successful image installation. It can be healthy even while the current change freeze and backout criteria problem remains.

Operational documents are useful only when they reflect the running state and its change history; stale diagrams waste troubleshooting effort. The indicated result—the maintained records identify current connections, configuration owners, network segments and the last validated change—checks a different mechanism and would not confirm the required change freeze and backout criteria outcome.

This would validate configuration backup before changes, not change freeze and backout criteria. Reversible change management requires knowing the previous effective state, not merely retaining a screenshot of intended edits. It is therefore insufficient acceptance evidence for the reported condition.

A guest can associate and receive a lease without completing the portal flow; redirect and pre-auth policy must permit necessary portal dependencies. Check captive-portal redirect path, DNS and allowed pre-authentication services. would address captive portal redirect fault, but the reported facts instead point to 802.1X supplicant disabled. That change would leave the actual requirement unresolved.

The alternative targets roaming reassociation delay, where roaming quality depends on usable overlap and timely client/security transitions; stationary speed tests cannot diagnose roaming interruption. It does not establish the intended 802.1X supplicant disabled behavior described in the scenario.

That action—Inspect STP port roles and topology before overriding a blocked redundant link—is relevant to spanning-tree blocked forwarding. A correctly blocked path may be essential loop prevention; unblocking without analyzing topology can trigger broadcasts and MAC instability. It does not correct the observed 802.1X supplicant disabled condition.

That result—Administrative access tests allow authorized management sources and reject unauthorized clients with attributable audit events—concerns management-plane security. Management interfaces and privileged control operations need narrower access than ordinary client traffic to reduce compromise and configuration risk. It can be healthy even while the current VSF versus VSX platform planning problem remains.

Two logical paths do not provide independent availability when they share a single cable route, power supply or upstream component. The indicated result—the resiliency checklist documents independent components and demonstrates recovery from each designated single failure—checks a different mechanism and would not confirm the required VSF versus VSX platform planning outcome.

This would validate access/distribution hierarchy, not VSF versus VSX platform planning. A functional hierarchy clarifies where endpoints attach, where traffic aggregates and where policy or Layer 3 boundaries belong. It is therefore insufficient acceptance evidence for the reported condition.

The alternative targets NAE event rules on AOS-CX, where AOS-CX NAE provides locally evaluated telemetry/event logic; defining useful triggers matters more than merely enabling generic monitoring. It does not establish the intended syslog event centralization behavior described in the scenario.

That action—Correlate related monitoring events and route prioritized alerts to appropriate responders—is relevant to alert correlation and noise reduction. Dependency-aware grouping prevents alert floods from hiding the primary failure and makes operational response more focused. It does not correct the observed syslog event centralization condition.

Release-specific feature and compatibility constraints can break management or forwarding despite a successful image installation. Verify supported firmware interoperability across dependent devices and management tools. would address firmware compatibility dependency, but the reported facts instead point to syslog event centralization. That change would leave the actual requirement unresolved.

Blindly trusting endpoint markings lets untrusted traffic dominate queues; classification must reflect approved service importance. Establish QoS trust boundaries and classify traffic according to validated application policy. would address trust and QoS marking boundary, but the reported facts instead point to uplink oversubscription tuning. That change would leave the actual requirement unresolved.

That action—Analyze LAG member utilization and flow-hashing behavior before claiming linear single-flow throughput—is relevant to LAG capacity and hash distribution. Standard link aggregation typically hashes an individual flow onto one member to avoid reordering; aggregate bandwidth benefits many flows more than one. It does not correct the observed uplink oversubscription tuning condition.

The alternative targets legacy low-rate airtime overhead, where low PHY data rates use more airtime per transmitted bit; rate changes must be constrained by coverage and device support. It does not establish the intended uplink oversubscription tuning behavior described in the scenario.

The alternative targets MAC authentication for headless devices, where MAC authentication can support devices without a supplicant but is weaker than cryptographic identity, so narrow policy and inventory are essential. It does not establish the intended SSID role and VLAN assignment behavior described in the scenario.

That action—Enable suitable BPDU protection on ports intended only for endpoints—is relevant to BPDU Guard at edge ports. Edge ports should not accept topology-control messages from unauthorized bridges; BPDU Guard can protect the switching domain by restricting offending links. It does not correct the observed SSID role and VLAN assignment condition.

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. Verify the AP's negotiated Ethernet link and available PoE power meet its installed feature requirements. would address AP uplink power and negotiation, but the reported facts instead point to SSID role and VLAN assignment. That change would leave the actual requirement unresolved.

That result—Under a reproducible congestion test, voice latency and jitter meet targets while other traffic remains serviceable—concerns voice queuing under load. QoS can prioritize selected packets when contention occurs but cannot create bandwidth; correct queue treatment reduces latency for critical applications. It can be healthy even while the current high-density WLAN airtime optimization problem remains.

Wide channels can improve peak rates per connection yet shrink available channel separation, raising cochannel contention in dense networks. The indicated result—peak-load tests show better aggregate throughput and fewer collisions with the selected width—checks a different mechanism and would not confirm the required high-density WLAN airtime optimization outcome.

This would validate legacy low-rate airtime overhead, not high-density WLAN airtime optimization. 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 action—Evaluate supported basic-rate settings and phase out unnecessary legacy rates after client compatibility testing—is relevant to legacy low-rate airtime overhead. Low PHY data rates use more airtime per transmitted bit; rate changes must be constrained by coverage and device support. It does not correct the observed WLAN channel-width optimization condition.

The alternative targets LAG capacity and hash distribution, where standard link aggregation typically hashes an individual flow onto one member to avoid reordering; aggregate bandwidth benefits many flows more than one. It does not establish the intended WLAN channel-width optimization behavior described in the scenario.

Downlink strength from a powerful AP does not increase client transmit capability; asymmetric links and oversized cells can harm roaming. Adjust transmit power to balance bidirectional coverage and cell size. would address transmit-power balance, but the reported facts instead point to WLAN channel-width optimization. That change would leave the actual requirement unresolved.

The 2.4 GHz band has limited nonoverlapping channel choices in typical regulatory domains, so channel overlap and wide channels intensify contention. Use appropriately separated 2.4 GHz channels and narrow channel widths for dense coverage. would address 2.4 GHz interference planning, but the reported facts instead point to 5 GHz regulatory channel constraints. That change would leave the actual requirement unresolved.

That action—Balance WLAN channel width against cell density and spectrum reuse—is relevant to high-density channel-width choice. Wider channels can raise peak link rates in isolation yet reduce the number of independent channels available in dense environments. It does not correct the observed 5 GHz regulatory channel constraints condition.

The alternative targets failure-domain isolation, where two logical paths do not provide independent availability when they share a single cable route, power supply or upstream component. It does not establish the intended 5 GHz regulatory channel constraints behavior described in the scenario.

That action—Install a destination route with a reachable next hop or appropriate outgoing interface—is relevant to static route and next-hop reachability. A route must identify the desired prefix and a valid forwarding path; a configured but unresolved next hop does not deliver packets. It does not correct the observed native VLAN alignment condition.

The alternative targets BPDU Guard at edge ports, where edge ports should not accept topology-control messages from unauthorized bridges; BPDU Guard can protect the switching domain by restricting offending links. It does not establish the intended native VLAN alignment behavior described in the scenario.

Authentication success is not the same as authorization; WLAN roles and VLAN selection determine where the user can forward traffic. Map the authenticated wireless identity to the intended role and network segment. would address SSID role and VLAN assignment, but the reported facts instead point to native VLAN alignment. That change would leave the actual requirement unresolved.

A data VLAN or management group cannot correct a switch power budget that denies the PD enough electrical power. Inspect the switch's per-port and aggregate PoE allocation against endpoint power requirements. would address power-over-Ethernet failure, but the reported facts instead point to optics compatibility and signal levels. That change would leave the actual requirement unresolved.

The alternative targets captive portal redirect fault, where a guest can associate and receive a lease without completing the portal flow; redirect and pre-auth policy must permit necessary portal dependencies. It does not establish the intended optics compatibility and signal levels behavior described in the scenario.

That action—Inspect the effective access VLAN and any role-based VLAN override on the affected port—is relevant to access VLAN misassignment. The VLAN used for an untagged or dynamically authorized session determines its broadcast and DHCP context; physical link state is not enough. It does not correct the observed optics compatibility and signal levels condition.
