That result—The active client session displays the correct assigned role and an explicit deny test confirms enforcement—concerns dynamic role enforcement. A RADIUS Access-Accept alone does not prove the switch or gateway applied the intended role policy to user sessions. It can be healthy even while the current AP country-code and RF regulatory setting problem remains.

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 AP country-code and RF regulatory setting outcome.

This would validate new Central scoped inheritance, not AP country-code and RF regulatory setting. New Central includes global, collection, site and device scopes; more specific applicable configuration can override broader inherited values. It is therefore insufficient acceptance evidence for the reported condition.

This would validate acceptance of WLAN security and mobility, not firmware feature-support planning. An AP advertising a network does not prove that clients can authenticate, receive approved privileges or maintain application continuity while moving. It is therefore insufficient acceptance evidence for the reported condition.

That result—The bill of materials and live PoE telemetry show that all expected powered endpoints fit within supported budget limits—concerns poE budget planning. Available port count does not establish available power; a switch can have free interfaces while its aggregate PoE budget is exhausted. It can be healthy even while the current firmware feature-support planning problem remains.

Changing many dependent control planes at once obscures root causes and enlarges outage blast radius; staging supplies evidence and rollback points. The indicated result—the implementation schedule contains bounded change groups, checkpoint tests and explicit reversal criteria before wider rollout—checks a different mechanism and would not confirm the required firmware feature-support planning outcome.

RF coverage establishes reception, whereas channel contention and client airtime demand govern usable capacity in dense spaces. Size the wireless design for peak concurrent airtime demand rather than signal strength alone. would address peak WLAN concurrency, but the reported facts instead point to address pool capacity. That change would leave the actual requirement unresolved.

That action—Model oversubscription and dimension distribution uplinks for peak traffic patterns—is relevant to uplink bandwidth capacity. Aggregate access capacity, application demand and supported congestion tolerance determine uplink sizing; port counts alone do not. It does not correct the observed address pool capacity condition.

The alternative targets campus requirements and acceptance criteria, where the low-level design should express observable outcomes such as authentication success, endpoint reachability, failover behavior and performance thresholds rather than only equipment names. It does not establish the intended address pool capacity behavior described in the scenario.

That action—Check SSID client-isolation policy before changing routes or AP power—is relevant to client isolation and peer access. Client isolation can intentionally prevent peer-to-peer wireless communication despite successful association, addressing and external reachability. It does not correct the observed IPv6 router-advertisement spoofing condition.

Endpoints without a supported supplicant need a deliberate alternative classification mechanism, not general unrestricted VLAN access. Verify the authorized non-802.1X identity path and its restricted fallback enforcement. would address MAC authentication fallback fault, but the reported facts instead point to IPv6 router-advertisement spoofing. That change would leave the actual requirement unresolved.

The alternative targets incorrect RADIUS role result, where a successful authentication indicates identity acceptance, while authorization attributes and local mapping determine permitted services. It does not establish the intended IPv6 router-advertisement spoofing behavior described in the scenario.

The alternative targets VRRP gateway resilience, where a virtual first-hop gateway provides a stable client next-hop while authorized peers coordinate active forwarding after failure. It does not establish the intended route redistribution filters 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 route redistribution filters condition.

IGMP membership information lets switches constrain Layer 2 multicast distribution instead of flooding traffic indiscriminately. Enable appropriate IGMP snooping and multicast forwarding behavior for subscriber VLANs. would address multicast receiver handling, but the reported facts instead point to route redistribution filters. That change would leave the actual requirement unresolved.

The alternative targets port mirroring for packet capture, where a capture tool sees only frames delivered to it; a correctly scoped mirror copies relevant ingress or egress traffic without changing production forwarding. It does not establish the intended baseline interface health metrics behavior described in the scenario.

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 baseline interface health metrics condition.

Centralized time-stamped records preserve context for multi-device analysis and avoid relying on volatile local event buffers. Forward relevant device and security logs to an authorized central log collector. would address syslog event centralization, but the reported facts instead point to baseline interface health metrics. That change would leave the actual requirement unresolved.

Recovery decisions based on elapsed time and service impact are more reliable than an operator's improvised judgment under incident pressure. The indicated result—change records show a clear checkpoint decision and a restore test when acceptance thresholds are not met—checks a different mechanism and would not confirm the required central client health visibility outcome.

This would validate alert correlation and noise reduction, not central client health visibility. Dependency-aware grouping prevents alert floods from hiding the primary failure and makes operational response more focused. It is therefore insufficient acceptance evidence for the reported condition.

That result—Sensor results report reachability and response timing for the designated application from the relevant location—concerns 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 can be healthy even while the current central client health visibility problem remains.

The alternative targets new Central scoped inheritance, where new Central includes global, collection, site and device scopes; more specific applicable configuration can override broader inherited values. It does not establish the intended multicast receiver handling behavior described in the scenario.

That action—Configure a controlled default route and distribute it only where the campus topology requires—is relevant to default-route propagation. A routing protocol's internal adjacency does not guarantee a usable route for unknown destinations; a valid and authorized default egress is needed. It does not correct the observed multicast receiver handling condition.

VSF presents supported physical members as a virtual switch while retaining operational requirements for healthy stacking links and member state. Provision the supported VSF stack topology, member roles and intermember links consistently. would address VSF member management, but the reported facts instead point to multicast receiver handling. That change would leave the actual requirement unresolved.

That result—The user subnet remains advertised by the routing process while no neighbor adjacency forms on the protected access VLAN—concerns OSPF passive interfaces. A passive interface can advertise its connected prefix through the process while avoiding unwanted OSPF hello exchanges toward endpoints. It can be healthy even while the current VRRP gateway resilience problem remains.

IGMP membership information lets switches constrain Layer 2 multicast distribution instead of flooding traffic indiscriminately. The indicated result—multicast reaches registered subscriber ports while nonmember access ports show no unnecessary stream traffic—checks a different mechanism and would not confirm the required VRRP gateway resilience outcome.

This would validate static route and next-hop reachability, not VRRP gateway resilience. A route must identify the desired prefix and a valid forwarding path; a configured but unresolved next hop does not deliver packets. It is therefore insufficient acceptance evidence for the reported condition.

The alternative targets LACP partner mismatch, where LACP only selects compatible links for aggregation; forcing an incompatible member can create unexpected hashing or forwarding behavior. It does not establish the intended access VLAN misassignment behavior described in the scenario.

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 access VLAN misassignment. That change would leave the actual requirement unresolved.

That action—Validate the AAA server path, UDP service and allowed transport before changing identity policies—is relevant to RADIUS server reachability. A silent RADIUS transport failure prevents normal authentication regardless of whether the user certificate or role rules are correct. It does not correct the observed access VLAN misassignment condition.

The alternative targets missing default gateway, where traffic bound for other subnets needs a reachable Layer 3 next hop; a functioning local broadcast domain does not provide routing. It does not establish the intended ACL deny versus service outage behavior described in the scenario.

That action—Verify the authorized non-802.1X identity path and its restricted fallback enforcement—is relevant to MAC authentication fallback fault. Endpoints without a supported supplicant need a deliberate alternative classification mechanism, not general unrestricted VLAN access. It does not correct the observed ACL deny versus service outage condition.

IPv4 ARP safeguards do not inspect ICMPv6 router announcements; RA protection constrains unauthorized router information on client segments. Apply appropriate IPv6 RA protection on untrusted access ports. would address IPv6 router-advertisement spoofing, but the reported facts instead point to ACL deny versus service outage. That change would leave the actual requirement unresolved.
