Radio operation is constrained by regional rules, and an incorrect country or channel plan can prevent valid operation or break client support. The indicated result—the AP radio state uses legally permitted channels and clients connect under the intended local regulatory settings—checks a different mechanism and would not confirm the required central configuration audit outcome.

This would validate spanning-tree loop prevention, not central configuration audit. Uncontrolled Ethernet loops replicate broadcasts and destabilize MAC learning; redundant links require a mechanism to block or logically aggregate unsafe cycles. It is therefore insufficient acceptance evidence for the reported condition.

That result—Rendered configurations contain the intended unique addresses and device settings with no unresolved placeholder values—concerns template variable rendering. Shared templates are reusable only when site-specific identity, address and port data are correctly substituted for each target device. It can be healthy even while the current central configuration audit problem remains.

That action—Measure convergence and application recovery time under designated failure tests—is relevant to failure recovery time objective. Resilience depends on recovery behavior, routing/bridging convergence and application tolerance, not the number of installed redundant devices. It does not correct the observed security-preserving optimization condition.

Co-channel neighbors share airtime when within interference range; thoughtful reuse can reduce contention without simply widening channels. Rebalance AP channel assignments using measured utilization and available independent channels. would address channel reuse planning, but the reported facts instead point to security-preserving optimization. That change would leave the actual requirement unresolved.

The alternative targets optimization with rollback, where a change may help one metric while degrading another; phased deployment and recovery thresholds protect production service continuity. It does not establish the intended security-preserving optimization behavior described in the scenario.

That result—The client-facing port shows the assigned access VLAN and obtains an address from the intended subnet—concerns access port VLAN membership. Client frames received untagged are placed in the port's access VLAN; a healthy physical link cannot compensate for wrong Layer 2 membership. It can be healthy even while the current static route and next-hop reachability problem remains.

This would validate spanning-tree loop prevention, not static route and next-hop reachability. Uncontrolled Ethernet loops replicate broadcasts and destabilize MAC learning; redundant links require a mechanism to block or logically aggregate unsafe cycles. It is therefore insufficient acceptance evidence for the reported condition.

A routing protocol's internal adjacency does not guarantee a usable route for unknown destinations; a valid and authorized default egress is needed. The indicated result—the intended device has an active default route toward the approved security edge and external test traffic uses it—checks a different mechanism and would not confirm the required static route and next-hop reachability outcome.

This would validate device group selection, not classic Central site versus group. A device must receive intent appropriate to its product family and role; the wrong group or persona can apply unrelated settings or reject configuration. It is therefore insufficient acceptance evidence for the reported condition.

That result—The AP radio state uses legally permitted channels and clients connect under the intended local regulatory settings—concerns AP country-code and RF regulatory setting. Radio operation is constrained by regional rules, and an incorrect country or channel plan can prevent valid operation or break client support. It can be healthy even while the current classic Central site versus group problem remains.

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 classic Central site versus group outcome.

The alternative targets 6 GHz WLAN compatibility, where 6 GHz operation requires capable client hardware and supported regulatory and security settings; enabling the band does not upgrade legacy adapters. It does not establish the intended directional antenna selection behavior described in the scenario.

VLANs divide Layer 2 domains, whereas VRFs maintain separate Layer 3 routing contexts; any intentional crossing needs controlled connectivity. Use VRFs where independent routing domains are required, with explicit permitted route exchange. would address routing and VRF separation, but the reported facts instead point to directional antenna selection. 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 directional antenna selection condition.

A planned change must include dependencies and a reversible path because a correct configuration can still disrupt business services during transition. The indicated result—the approved implementation plan states change windows, rollback thresholds, recovery owner and end-to-end validation steps—checks a different mechanism and would not confirm the required firmware feature-support planning outcome.

That result—The identity design includes certificate enrollment, renewal, revocation and a successful mutual-trust authentication test—concerns EAP-TLS certificate lifecycle. EAP-TLS authenticates with certificates, so healthy network transport alone cannot correct absent trust, expired credentials or unmanaged key lifecycle. It can be healthy even while the current firmware feature-support planning problem remains.

This would validate role-based access decisions, not firmware feature-support planning. Successful authentication proves identity; separate authorization decisions determine permitted destinations, services and segmentation. It is therefore insufficient acceptance evidence for the reported condition.

That result—Positive and negative flow tests confirm approved connectivity and continuing rejection of disallowed destinations—concerns access-control change verification. Successful application traffic is only half of policy correctness; overbroad authorization can create exposure while the reported symptom appears resolved. It can be healthy even while the current firmware rollout staging problem remains.

Counters are most useful when compared with known normal operating behavior and collection intervals rather than isolated snapshots. The indicated result—time-series telemetry shows documented normal ranges and highlights material changes from the baseline—checks a different mechanism and would not confirm the required firmware rollout staging outcome.

This would validate firmware compatibility dependency, not firmware rollout staging. Release-specific feature and compatibility constraints can break management or forwarding despite a successful image installation. It is therefore insufficient acceptance evidence for the reported condition.

That action—Apply appropriate IPv6 RA protection on untrusted access ports—is relevant to IPv6 router-advertisement spoofing. IPv4 ARP safeguards do not inspect ICMPv6 router announcements; RA protection constrains unauthorized router information on client segments. It does not correct the observed wrong Central scope override condition.

The alternative targets access VLAN misassignment, where 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 establish the intended wrong Central scope override behavior described in the scenario.

Successful reboot and version display do not establish that all intended policies and interface behaviors survived the change. Compare post-upgrade effective settings with the saved pre-upgrade baseline and release compatibility. would address firmware-induced configuration drift, but the reported facts instead point to wrong Central scope override. That change would leave the actual requirement unresolved.

This would validate physical layer link fault, not missing trunk VLAN. Repeated link transitions and frame errors point to Layer 1 quality or negotiation rather than an unseen WLAN authentication issue. It is therefore insufficient acceptance evidence for the reported condition.

That result—The selected RF adjustment reduces retries and busy-channel time without causing new coverage holes—concerns RF interference and retries. Strong signal cannot cure collisions or non-Wi-Fi interference; airtime contention and retransmission consume the shared radio medium. It can be healthy even while the current missing trunk VLAN problem remains.

An unsupported or poorly coupled optical path prevents reliable Ethernet signalling regardless of correct routing or authentication configuration. The indicated result—supported optics show acceptable diagnostics and stable link state across a representative traffic test—checks a different mechanism and would not confirm the required missing trunk VLAN outcome.

The alternative targets multicast traffic scope, where subscriber tracking lets a switch direct multicast toward active receivers instead of flooding every port, protecting shared access bandwidth. It does not establish the intended uplink oversubscription tuning behavior described in the scenario.

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.

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 uplink oversubscription tuning. That change would leave the actual requirement unresolved.

The alternative targets configuration revision and approval history, where auditability requires associating control-plane changes with an identity, time, reason and prior state, not just the new value. It does not establish the intended network asset lifecycle behavior described in the scenario.

API access is a privileged operational interface; overbroad or leaked tokens can compromise configuration and monitoring data. Use narrowly authorized API credentials and protect their storage and renewal lifecycle. would address REST API authentication boundaries, but the reported facts instead point to network asset lifecycle. That change would leave the actual requirement unresolved.

That action—Compare effective device configuration with Central intent and reconcile approved local overrides—is relevant to config drift after manual overrides. Undocumented differences make subsequent upgrades and incident response unpredictable because the managed baseline is no longer authoritative. It does not correct the observed network asset lifecycle condition.
