This would validate 2.4 GHz interference planning, not RADIUS service resilience. 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.

An AP advertising a network does not prove that clients can authenticate, receive approved privileges or maintain application continuity while moving. The indicated result—test records show representative clients join, receive correct roles, roam and reach only approved services—checks a different mechanism and would not confirm the required RADIUS service resilience 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 RADIUS service resilience problem remains.

That action—Align OSPF interface network, area, timers and authentication requirements across neighbors—is relevant to OSPF adjacency prerequisites. OSPF adjacency depends on compatible peer parameters and reachable interfaces; a live link is insufficient when control-plane settings disagree. It does not correct the observed VSF member management condition.

When connected trunk ports disagree about how untagged frames are classified, management and user traffic can land in unintended segments. Align trunk native VLAN expectations and avoid ambiguous untagged forwarding. would address native VLAN alignment, but the reported facts instead point to VSF member management. That change would leave the actual requirement unresolved.

The alternative targets multicast receiver handling, where IGMP membership information lets switches constrain Layer 2 multicast distribution instead of flooding traffic indiscriminately. It does not establish the intended VSF member management behavior described in the scenario.

That result—Client reports identify the actual failing association or onboarding stage for affected endpoints—concerns central client health visibility. An AP online indicator does not prove successful client onboarding; stage-specific events narrow diagnosis to radio, identity, addressing or portal dependencies. It can be healthy even while the current configuration backup before changes problem remains.

Successful application traffic is only half of policy correctness; overbroad authorization can create exposure while the reported symptom appears resolved. The indicated result—positive and negative flow tests confirm approved connectivity and continuing rejection of disallowed destinations—checks a different mechanism and would not confirm the required configuration backup before changes outcome.

This would validate AAA change coordination, not configuration backup before changes. Identity changes impact access before network routing tests can begin; testing distinct client classes limits unintended lockouts. It is therefore insufficient acceptance evidence for the reported condition.

This would validate unauthorized DHCP server, not RADIUS accounting versus authorization. DHCP snooping restricts untrusted hosts from responding as servers and can help preserve legitimate addressing information on the VLAN. It is therefore insufficient acceptance evidence for the reported condition.

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 RADIUS accounting versus authorization outcome.

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 RADIUS accounting versus authorization problem remains.

The alternative targets OSPF adjacency prerequisites, where OSPF adjacency depends on compatible peer parameters and reachable interfaces; a live link is insufficient when control-plane settings disagree. It does not establish the intended SSID role and VLAN assignment behavior described in the scenario.

That action—Bind returned authorization roles to correct local or downloadable enforcement behavior—is relevant to dynamic role enforcement. A RADIUS Access-Accept alone does not prove the switch or gateway applied the intended role policy to user sessions. It does not correct the observed SSID role and VLAN assignment condition.

Association and address assignment alone cannot enforce guest registration or policy acceptance; the portal and post-login role must be connected. Implement the authorized guest captive-portal workflow and associated access policy. would address guest captive-portal flow, but the reported facts instead point to SSID role and VLAN assignment. That change would leave the actual requirement unresolved.

This would validate VSX keepalive isolation, not OSPF adjacency prerequisites. Separate failure detection helps peers distinguish link disruption from peer loss, reducing the risk of harmful split-brain behavior. It is therefore insufficient acceptance evidence for the reported condition.

That result—A peer failure preserves client reachability to the virtual gateway and restores traffic within the approved recovery target—concerns VRRP gateway resilience. A virtual first-hop gateway provides a stable client next-hop while authorized peers coordinate active forwarding after failure. It can be healthy even while the current OSPF adjacency prerequisites problem remains.

Classic Central uses groups to distribute shared configuration while sites provide physical-location organization, so modifying location alone need not change running intent. The indicated result—the device has correct site metadata and independently verified group-level configuration assignments—checks a different mechanism and would not confirm the required OSPF adjacency prerequisites outcome.

The alternative targets peak WLAN concurrency, where RF coverage establishes reception, whereas channel contention and client airtime demand govern usable capacity in dense spaces. It does not establish the intended inventory and dependency discovery behavior described in the scenario.

The low-level design should express observable outcomes such as authentication success, endpoint reachability, failover behavior and performance thresholds rather than only equipment names. Translate business requirements into measurable network acceptance criteria before selecting configurations. would address campus requirements and acceptance criteria, but the reported facts instead point to inventory and dependency discovery. 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 inventory and dependency discovery condition.

An AP advertising a network does not prove that clients can authenticate, receive approved privileges or maintain application continuity while moving. The indicated result—test records show representative clients join, receive correct roles, roam and reach only approved services—checks a different mechanism and would not confirm the required firmware feature-support planning outcome.

This would validate directional antenna selection, not firmware feature-support planning. Directional gain shapes energy into target areas and can reduce unwanted spill, but a poorly aimed directional antenna creates coverage holes elsewhere. It is therefore insufficient acceptance evidence for the reported condition.

That result—Administrative access tests allow authorized management sources and reject unauthorized clients with attributable audit events—concerns management-plane security. Management interfaces and privileged control operations need narrower access than ordinary client traffic to reduce compromise and configuration risk. It can be healthy even while the current firmware feature-support planning problem remains.

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 SVI down due to VLAN state. 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 SVI down due to VLAN state condition.

The alternative targets asymmetric path enforcement, where stateful firewalls can drop replies they did not see established; checking only the outbound route misses asymmetric forwarding. It does not establish the intended SVI down due to VLAN state behavior described in the scenario.

That result—The correct VRF has an installed destination route and permitted traffic uses the intended next hop—concerns route missing in correct VRF. Separate VRFs maintain distinct forwarding information bases; routes visible in one context do not automatically apply in another. It can be healthy even while the current OSPF authentication mismatch problem remains.

This would validate wireless DHCP failure stage, not OSPF authentication mismatch. Client association and 802.1X success occur before address allocation; VLAN or relay faults can prevent DHCP without an RF fault. It is therefore insufficient acceptance evidence for the reported condition.

A healthy neighbor relationship does not imply every desired route is present; network statements, redistribution and policy can omit a prefix. The indicated result—core routers learn the correct new prefix with an intended next hop and return traffic succeeds—checks a different mechanism and would not confirm the required OSPF authentication mismatch outcome.

That action—Map the authenticated wireless identity to the intended role and network segment—is relevant to SSID role and VLAN assignment. Authentication success is not the same as authorization; WLAN roles and VLAN selection determine where the user can forward traffic. It does not correct the observed RADIUS shared-secret consistency condition.

Wireless features depend on the wired uplink and power available to the AP; sufficient coverage does not prove the device is operating at full capacity. Verify the AP's negotiated Ethernet link and available PoE power meet its installed feature requirements. would address AP uplink power and negotiation, but the reported facts instead point to RADIUS shared-secret consistency. That change would leave the actual requirement unresolved.

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 RADIUS shared-secret consistency behavior described in the scenario.
