A device must receive intent appropriate to its product family and role; the wrong group or persona can apply unrelated settings or reject configuration. Assign devices to compatible Central groups or functions before applying shared configurations. would address device group selection, but the reported facts instead point to central device inventory onboarding. That change would leave the actual requirement unresolved.

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 central device inventory onboarding condition.

The alternative targets gateway role deployment, where gateway responsibilities such as tunnel termination and role enforcement depend on the chosen software architecture and supported role. It does not establish the intended central device inventory onboarding behavior described in the scenario.

This would validate missing trunk VLAN, not power-over-Ethernet failure. A frame cannot traverse a trunk on which its tagged VLAN is not allowed; local endpoint configuration can be fully correct. It is therefore insufficient acceptance evidence for the reported condition.

That result—The neighbor reaches Full and logs no authentication failures after the matched configuration is applied—concerns OSPF authentication mismatch. Routing protocol control packets may be rejected when authentication differs, even if underlying Layer 3 ping succeeds. It can be healthy even while the current power-over-Ethernet failure problem remains.

Rapid MAC moves and broadcast amplification indicate switching topology instability, not a problem fixed by adding a default route. The indicated result—the repaired topology has stable learned MAC locations and broadcast volume returns to expected baseline—checks a different mechanism and would not confirm the required power-over-Ethernet failure outcome.

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.

Authentication and authorization can work while accounting packets are missing; reliable session tracking needs the additional accounting path. Check RADIUS accounting events and collector reachability separately from login authorization. would address RADIUS accounting versus authorization, but the reported facts instead point to 802.1X supplicant disabled. That change would leave the actual requirement unresolved.

That action—Inspect EAP-TLS certificate trust, validity and identity on both authentication sides—is relevant to EAP-TLS trust-chain failure. EAP-TLS relies on a trusted certificate path; successful network reachability does not bypass expired or unknown issuing authorities. It does not correct the observed 802.1X supplicant disabled condition.

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 storm control tuning problem remains.

This would validate multicast traffic scope, not storm control tuning. Subscriber tracking lets a switch direct multicast toward active receivers instead of flooding every port, protecting shared access bandwidth. It is therefore insufficient acceptance evidence for the reported condition.

Standard link aggregation typically hashes an individual flow onto one member to avoid reordering; aggregate bandwidth benefits many flows more than one. The indicated result—member counters show expected distribution across multiple flows and single-flow limits are accounted for in capacity planning—checks a different mechanism and would not confirm the required storm control tuning outcome.

This would validate MAC learning and unintended loops, not missing trunk VLAN. Rapid MAC moves and broadcast amplification indicate switching topology instability, not a problem fixed by adding a default route. It is therefore insufficient acceptance evidence for the reported condition.

That result—Both interfaces report compatible negotiated parameters and throughput tests show no related error growth—concerns duplex and speed negotiation. Mismatched physical link parameters can create collisions or errors despite a link-up status, so higher-layer policy changes cannot repair them. It can be healthy even while the current missing trunk VLAN problem remains.

Client isolation can intentionally prevent peer-to-peer wireless communication despite successful association, addressing and external reachability. The indicated result—the intended peer-access policy is confirmed and permitted test clients connect while prohibited peers remain isolated—checks a different mechanism and would not confirm the required missing trunk VLAN outcome.

VSX peers retain independent control planes and only designated supported feature sets synchronize; unchecked settings may diverge. The indicated result—both VSX peers display expected synchronized state and intentional independent routing configurations remain correct—checks a different mechanism and would not confirm the required default-route propagation outcome.

This would validate VRF route-context configuration, not default-route propagation. Routes and interfaces are looked up within the relevant VRF; a default route in a different table cannot repair a missing path. It is therefore insufficient acceptance evidence for the reported condition.

That result—An isolated link-failure exercise records the intended peer health state and avoids duplicate active forwarding—concerns VSX keepalive isolation. Separate failure detection helps peers distinguish link disruption from peer loss, reducing the risk of harmful split-brain behavior. It can be healthy even while the current default-route propagation problem remains.

That action—Configure the required VLAN interfaces and routed gateway paths for intended inter-VLAN communication—is relevant to SVI inter-VLAN gateway. VLAN configuration creates Layer 2 separation; inter-subnet communication requires appropriate Layer 3 interfaces, addressing and policy. It does not correct the observed access port VLAN membership condition.

The alternative targets DHCP relay on routed segments, where layer 3 boundaries do not normally forward client DHCP broadcasts without relay behavior; the helper target must also be reachable. It does not establish the intended access port VLAN membership behavior described in the scenario.

Classic Central uses groups to distribute shared configuration while sites provide physical-location organization, so modifying location alone need not change running intent. Distinguish Central's site/location assignment from the group-based configuration scope in Classic Central. would address classic Central site versus group, but the reported facts instead point to access port VLAN membership. That change would leave the actual requirement unresolved.

That result—The post-change channel plan reduces nearby cochannel competition and measured client retries—concerns channel reuse planning. Co-channel neighbors share airtime when within interference range; thoughtful reuse can reduce contention without simply widening channels. It can be healthy even while the current transmit-power balance problem remains.

Access port sum can greatly exceed distribution bandwidth, so congestion and burst tolerance must be planned rather than inferred from port speed labels. The indicated result—updated uplink capacity and measured utilization support the busiest expected periods without material drops—checks a different mechanism and would not confirm the required transmit-power balance outcome.

This would validate legacy low-rate airtime overhead, not transmit-power balance. 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—Use UXI-style synthetic experience testing from representative user locations—is relevant to UXI application tests. Network device health does not establish application experience; end-to-end synthetic tests expose DNS, transport and service delays along the client path. It does not correct the observed alert correlation and noise reduction condition.

Monitoring requires authorized protocol access and device-supported counters; the existence of a monitoring server alone produces no reliable telemetry. Configure supported SNMP monitoring and validate selected interface and system objects. would address SNMP monitoring scope, but the reported facts instead point to alert correlation and noise reduction. That change would leave the actual requirement unresolved.

The alternative targets API paging and rate limits, where management APIs may return segmented data or throttle callers, so automation must recognize incomplete and transient outcomes instead of silently succeeding. It does not establish the intended alert correlation and noise reduction behavior described in the scenario.

Endpoints without a supported supplicant need a deliberate alternative classification mechanism, not general unrestricted VLAN access. The indicated result—the registered device receives its restricted role and unregistered devices remain blocked or quarantined—checks a different mechanism and would not confirm the required central API unauthorized response outcome.

That result—Test rogue advertisements are blocked while approved router advertisements continue to reach clients—concerns IPv6 router-advertisement spoofing. IPv4 ARP safeguards do not inspect ICMPv6 router announcements; RA protection constrains unauthorized router information on client segments. It can be healthy even while the current central API unauthorized response problem remains.

This would validate missing trunk VLAN, not central API unauthorized response. A frame cannot traverse a trunk on which its tagged VLAN is not allowed; local endpoint configuration can be fully correct. It is therefore insufficient acceptance evidence for the reported condition.

API access is a privileged operational interface; overbroad or leaked tokens can compromise configuration and monitoring data. The indicated result—a scoped automation token reads intended resources, fails prohibited write operations and is absent from code repositories—checks a different mechanism and would not confirm the required API paging and rate limits outcome.

This would validate central client health visibility, not API paging and rate limits. An AP online indicator does not prove successful client onboarding; stage-specific events narrow diagnosis to radio, identity, addressing or portal dependencies. It is therefore insufficient acceptance evidence for the reported condition.

That result—The asset record reflects disposition and retired device identities no longer retain unintended management authorization—concerns network asset lifecycle. Stale registrations and credentials introduce operational confusion and potential access risk even when hardware is no longer installed. It can be healthy even while the current API paging and rate limits problem remains.
