This would validate power-over-Ethernet failure, not physical layer link fault. A data VLAN or management group cannot correct a switch power budget that denies the PD enough electrical power. It is therefore insufficient acceptance evidence for the reported condition.

That result—The session is assigned the approved VLAN and receives the expected subnet's gateway and address settings—concerns 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 can be healthy even while the current physical layer link fault problem remains.

IPv4 ARP safeguards do not inspect ICMPv6 router announcements; RA protection constrains unauthorized router information on client segments. The indicated result—test rogue advertisements are blocked while approved router advertisements continue to reach clients—checks a different mechanism and would not confirm the required physical layer link fault outcome.

That result—Queue counters and packet markings confirm trusted voice traffic receives priority while guest bulk flows remain appropriately classified—concerns trust and QoS marking boundary. Blindly trusting endpoint markings lets untrusted traffic dominate queues; classification must reflect approved service importance. It can be healthy even while the current storm control tuning problem remains.

This would validate uplink oversubscription tuning, not storm control tuning. Access port sum can greatly exceed distribution bandwidth, so congestion and burst tolerance must be planned rather than inferred from port speed labels. It is therefore insufficient acceptance evidence for the reported condition.

Optimization claims require equivalent loads, test methods and service metrics before and after; otherwise changes in demand confound comparison. The indicated result—the report contrasts like-for-like baseline and post-change throughput, latency, retries and error statistics—checks a different mechanism and would not confirm the required storm control tuning outcome.

A route must identify the desired prefix and a valid forwarding path; a configured but unresolved next hop does not deliver packets. Install a destination route with a reachable next hop or appropriate outgoing interface. would address static route and next-hop reachability, but the reported facts instead point to VRF route-context configuration. That change would leave the actual requirement unresolved.

The alternative targets spanning-tree loop prevention, where uncontrolled Ethernet loops replicate broadcasts and destabilize MAC learning; redundant links require a mechanism to block or logically aggregate unsafe cycles. It does not establish the intended VRF route-context configuration behavior described in the scenario.

That action—Select the correct device function/persona when assigning New Central configuration profiles—is relevant to new Central persona applicability. Configuration applies according to supported device function as well as scope, so a role mismatch can prevent intended policy from being deployed. It does not correct the observed VRF route-context configuration condition.

That result—The session is assigned the approved VLAN and receives the expected subnet's gateway and address settings—concerns 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 can be healthy even while the current client isolation and peer access problem remains.

This would validate wrong Central scope override, not client isolation and peer access. Scoped configuration precedence can explain isolated divergence; changing the shared profile again can unintentionally impact healthy devices. It is therefore insufficient acceptance evidence for the reported condition.

Authentication and authorization can work while accounting packets are missing; reliable session tracking needs the additional accounting path. The indicated result—the AAA collector receives accurate start/stop accounting records for the authorized client session—checks a different mechanism and would not confirm the required client isolation and peer access outcome.

IP forwarding selects the most specific matching destination prefix before comparing less-specific alternatives; a summary route does not override a more-specific match. Inspect matching route prefixes and prefer the longest matching prefix in path analysis. would address longest-prefix route selection, but the reported facts instead point to client isolation and peer access. That change would leave the actual requirement unresolved.

That action—Inspect applied scopes and higher-precedence device overrides for the affected component—is relevant to wrong Central scope override. Scoped configuration precedence can explain isolated divergence; changing the shared profile again can unintentionally impact healthy devices. It does not correct the observed client isolation and peer access condition.

The alternative targets MAC authentication fallback fault, where endpoints without a supported supplicant need a deliberate alternative classification mechanism, not general unrestricted VLAN access. It does not establish the intended client isolation and peer access behavior described in the scenario.

That result—The LAG status shows intended active members with consistent partner identifiers and forwarding behavior—concerns LACP bundled links. Aggregated links require compatible control and interface parameters; mismatched LACP or VLAN settings can prevent members from joining. It can be healthy even while the current MAC authentication for headless devices problem remains.

Association and address assignment alone cannot enforce guest registration or policy acceptance; the portal and post-login role must be connected. The indicated result—a first-time visitor is presented the expected portal and gains only the approved access after completing it—checks a different mechanism and would not confirm the required MAC authentication for headless devices outcome.

This would validate wired 802.1X port control, not MAC authentication for headless devices. An AAA server cannot enforce identity on a port whose access-control mechanism is disabled; unauthorized endpoints must receive a restricted result. It is therefore insufficient acceptance evidence for the reported condition.

That action—Use RF spectrum evidence to locate and mitigate non-Wi-Fi interference—is relevant to 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 does not correct the observed legacy low-rate airtime overhead condition.

Resilience depends on recovery behavior, routing/bridging convergence and application tolerance, not the number of installed redundant devices. Measure convergence and application recovery time under designated failure tests. would address failure recovery time objective, but the reported facts instead point to legacy low-rate airtime overhead. That change would leave the actual requirement unresolved.

The alternative targets channel reuse planning, where co-channel neighbors share airtime when within interference range; thoughtful reuse can reduce contention without simply widening channels. It does not establish the intended legacy low-rate airtime overhead behavior described in the scenario.

This would validate VSF versus VSX platform planning, not critical application traffic profile. VSF forms a virtual switch with supported stacking members; VSX coordinates two peers while retaining separate control planes, so support and failure domains differ. It is therefore insufficient acceptance evidence for the reported condition.

Missing uplink, power, VLAN, routing and identity dependencies cause apparently successful device replacements to disconnect applications or clients unexpectedly. The indicated result—a validated inventory identifies uplinks, upstream routes, address services, identity services and critical endpoint relationships—checks a different mechanism and would not confirm the required critical application traffic profile outcome.

That result—The capacity model and busy-period test account for concurrent clients, channel airtime and application throughput—concerns peak WLAN concurrency. RF coverage establishes reception, whereas channel contention and client airtime demand govern usable capacity in dense spaces. It can be healthy even while the current critical application traffic profile problem remains.

That action—Capture a restorable configuration checkpoint and change record before modifying network intent—is relevant to configuration backup before changes. Reversible change management requires knowing the previous effective state, not merely retaining a screenshot of intended edits. It does not correct the observed firmware compatibility dependency condition.

AOS-CX NAE provides locally evaluated telemetry/event logic; defining useful triggers matters more than merely enabling generic monitoring. Deploy supported Network Analytics Engine agents with event conditions and response actions. would address NAE event rules on AOS-CX, but the reported facts instead point to firmware compatibility dependency. That change would leave the actual requirement unresolved.

The alternative targets config drift after manual overrides, where undocumented differences make subsequent upgrades and incident response unpredictable because the managed baseline is no longer authoritative. It does not establish the intended firmware compatibility dependency behavior described in the scenario.

That result—RADIUS requests and responses traverse the approved path and the client reaches its intended authorized role—concerns RADIUS server reachability. A silent RADIUS transport failure prevents normal authentication regardless of whether the user certificate or role rules are correct. It can be healthy even while the current AP radio disabled or unsupported channel problem remains.

This would validate access VLAN misassignment, not AP radio disabled or unsupported channel. The VLAN used for an untagged or dynamically authorized session determines its broadcast and DHCP context; physical link state is not enough. It is therefore insufficient acceptance evidence for the reported condition.

A successful authentication indicates identity acceptance, while authorization attributes and local mapping determine permitted services. The indicated result—the client session reports the approved role and positive/negative application tests match that role's permissions—checks a different mechanism and would not confirm the required AP radio disabled or unsupported channel outcome.

This would validate RADIUS shared-secret consistency, not wired 802.1X port control. RADIUS exchanges rely on correctly configured shared secrets and client definitions; basic IP reachability does not establish a valid AAA relationship. It is therefore insufficient acceptance evidence for the reported condition.

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 wired 802.1X port control 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 wired 802.1X port control problem remains.
