That action—Inspect token scopes and endpoint authorization when the API returns a forbidden response—is relevant to central API unauthorized response. A valid login or token does not imply access to every management resource; 403 generally indicates denied permissions rather than a switch port failure. It does not correct the observed incorrect RADIUS role result condition.

The alternative targets wireless DHCP failure stage, where client association and 802.1X success occur before address allocation; VLAN or relay faults can prevent DHCP without an RF fault. It does not establish the intended incorrect RADIUS role result behavior described in the scenario.

Cloud device online status does not prove every radio is active or that target clients can discover the selected channel. Check AP radio administrative state, band and regulatory channel support. would address AP radio disabled or unsupported channel, but the reported facts instead point to incorrect RADIUS role result. That change would leave the actual requirement unresolved.

That result—The stack reports the expected active members and resilient forwarding across an intended member failure—concerns VSF member management. VSF presents supported physical members as a virtual switch while retaining operational requirements for healthy stacking links and member state. It can be healthy even while the current new Central persona applicability problem remains.

New Central includes global, collection, site and device scopes; more specific applicable configuration can override broader inherited values. The indicated result—the effective device configuration reflects documented scoped intent and any deliberate higher-priority exception—checks a different mechanism and would not confirm the required new Central persona applicability outcome.

This would validate template variable rendering, not new Central persona applicability. Shared templates are reusable only when site-specific identity, address and port data are correctly substituted for each target device. It is therefore insufficient acceptance evidence for the reported condition.

The alternative targets certificate expiry monitoring, where healthy RF and RADIUS reachability cannot compensate for an expired or untrusted certificate that fails the authentication handshake. It does not establish the intended firmware compatibility dependency behavior described in the scenario.

Software changes can alter forwarding, management or authentication behavior, so a limited pilot provides evidence before broad deployment. Pilot firmware upgrades on representative devices and stage production waves with rollback options. would address firmware rollout staging, but the reported facts instead point to firmware compatibility dependency. That change would leave the actual requirement unresolved.

That action—Use narrowly authorized API credentials and protect their storage and renewal lifecycle—is relevant to REST API authentication boundaries. API access is a privileged operational interface; overbroad or leaked tokens can compromise configuration and monitoring data. It does not correct the observed firmware compatibility dependency condition.

The alternative targets physical layer link fault, where repeated link transitions and frame errors point to Layer 1 quality or negotiation rather than an unseen WLAN authentication issue. It does not establish the intended incorrect RADIUS role result behavior described in the scenario.

That action—Measure channel utilization, interference and retries before changing AP power—is relevant to RF interference and retries. Strong signal cannot cure collisions or non-Wi-Fi interference; airtime contention and retransmission consume the shared radio medium. It does not correct the observed incorrect RADIUS role result condition.

Client association and 802.1X success occur before address allocation; VLAN or relay faults can prevent DHCP without an RF fault. Trace DHCP relay, VLAN forwarding and server responses after successful WLAN authentication. would address wireless DHCP failure stage, but the reported facts instead point to incorrect RADIUS role result. That change would leave the actual requirement unresolved.

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 directional antenna selection outcome.

This would validate 2.4 GHz interference planning, not directional antenna selection. The 2.4 GHz band has limited nonoverlapping channel choices in typical regulatory domains, so channel overlap and wide channels intensify contention. It is therefore insufficient acceptance evidence for the reported condition.

That result—Walking-call tests show successful transitions with latency and loss remaining within the voice application's limits—concerns roaming voice coverage overlap. A reliable voice WLAN needs usable signal and timely authentication/roaming behavior between neighboring cells, not maximum isolated AP range. It can be healthy even while the current directional antenna selection problem remains.

That action—Check the endpoint's 802.1X supplicant configuration and initial EAPOL exchange—is relevant to 802.1X supplicant disabled. An authentication server cannot authorize an endpoint that never initiates the intended EAP handshake on the controlled link. It does not correct the observed wireless DHCP failure stage condition.

Mismatched physical link parameters can create collisions or errors despite a link-up status, so higher-layer policy changes cannot repair them. Verify compatible link speed, duplex and negotiation settings on both interface ends. would address duplex and speed negotiation, but the reported facts instead point to wireless DHCP failure stage. 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 wireless DHCP failure stage behavior described in the scenario.

This would validate BPDU Guard at edge ports, not RADIUS shared-secret consistency. Edge ports should not accept topology-control messages from unauthorized bridges; BPDU Guard can protect the switching domain by restricting offending links. It is therefore insufficient acceptance evidence for the reported condition.

MAC authentication can support devices without a supplicant but is weaker than cryptographic identity, so narrow policy and inventory are essential. The indicated result—the registered device reaches only its designated services and unknown MAC identities are denied or quarantined—checks a different mechanism and would not confirm the required RADIUS shared-secret consistency outcome.

That result—A representative approved device completes certificate-based enterprise authentication and receives its authorized network role—concerns corporate EAP-TLS SSID. EAP-TLS verifies certificate-based identities through the configured authentication system; a shared PSK does not give per-device certificate identity. It can be healthy even while the current RADIUS shared-secret consistency problem remains.

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 SSID role and VLAN assignment. That change would leave the actual requirement unresolved.

The alternative targets guest captive-portal flow, where association and address assignment alone cannot enforce guest registration or policy acceptance; the portal and post-login role must be connected. It does not establish the intended SSID role and VLAN assignment behavior described in the scenario.

That action—Enable wired 802.1X port-access control with the intended authentication and fallback policy—is relevant to wired 802.1X port control. An AAA server cannot enforce identity on a port whose access-control mechanism is disabled; unauthorized endpoints must receive a restricted result. It does not correct the observed SSID role and VLAN assignment condition.

This would validate 5 GHz regulatory channel constraints, not 2.4 GHz interference planning. Allowed frequencies, radar-detection obligations and client capabilities can vary by country and AP model, so global channel templates may fail. It is therefore insufficient acceptance evidence for the reported condition.

That result—Walking-call tests show successful transitions with latency and loss remaining within the voice application's limits—concerns roaming voice coverage overlap. A reliable voice WLAN needs usable signal and timely authentication/roaming behavior between neighboring cells, not maximum isolated AP range. It can be healthy even while the current 2.4 GHz interference planning problem remains.

Identity services become campus availability dependencies; redundant switches cannot authenticate users when all RADIUS paths fail. The indicated result—a controlled AAA failover test confirms appropriate continued or restricted access under the documented policy—checks a different mechanism and would not confirm the required 2.4 GHz interference planning outcome.

That action—Capture a comparable pre-change performance baseline and define a repeatable post-change test—is relevant to baseline before optimization. Optimization claims require equivalent loads, test methods and service metrics before and after; otherwise changes in demand confound comparison. It does not correct the observed failure recovery time objective 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 failure recovery time objective. That change would leave the actual requirement unresolved.

The alternative targets client experience versus device uptime, where infrastructure availability is necessary but not sufficient for usable service; end-to-end user journeys expose service dependencies beyond device health. It does not establish the intended failure recovery time objective behavior described in the scenario.

Accurate time supports certificate validation, event correlation and change records; unsynchronized clocks obscure cause and effect. The indicated result—switches, gateways and authentication servers report synchronized time and event timestamps align across collected logs—checks a different mechanism and would not confirm the required certificate expiry monitoring outcome.

That result—A pilot validates critical services and the production plan provides checkpoints, maintenance windows and restoration conditions—concerns firmware rollout staging. Software changes can alter forwarding, management or authentication behavior, so a limited pilot provides evidence before broad deployment. It can be healthy even while the current certificate expiry monitoring problem remains.

This would validate configuration backup before changes, not certificate expiry monitoring. 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.
