This would validate AP country-code and RF regulatory setting, not gateway role deployment. Radio operation is constrained by regional rules, and an incorrect country or channel plan can prevent valid operation or break client support. It is therefore insufficient acceptance evidence for the reported condition.

That result—An unauthorized BPDU on the protected access port triggers the configured protective behavior without altering the campus root—concerns 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 can be healthy even while the current gateway role deployment problem remains.

A device must receive intent appropriate to its product family and role; the wrong group or persona can apply unrelated settings or reject configuration. The indicated result—the provisioned device reports the intended group and compatible configuration with no unaddressed sync errors—checks a different mechanism and would not confirm the required gateway role deployment outcome.

The alternative targets VSF versus VSX platform planning, where 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 does not establish the intended routing and VRF separation behavior described in the scenario.

6 GHz operation requires capable client hardware and supported regulatory and security settings; enabling the band does not upgrade legacy adapters. Check 6 GHz client support, country rules and applicable WLAN security requirements before rollout. would address 6 GHz WLAN compatibility, but the reported facts instead point to routing and VRF separation. That change would leave the actual requirement unresolved.

That action—Assign clear access, aggregation and routing roles and validate their traffic and scale requirements—is relevant to access/distribution hierarchy. A functional hierarchy clarifies where endpoints attach, where traffic aggregates and where policy or Layer 3 boundaries belong. It does not correct the observed routing and VRF separation condition.

The alternative targets OSPF authentication mismatch, where routing protocol control packets may be rejected when authentication differs, even if underlying Layer 3 ping succeeds. It does not establish the intended asymmetric path enforcement behavior described in the scenario.

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 asymmetric path enforcement. That change would leave the actual requirement unresolved.

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 asymmetric path enforcement condition.

If IP connectivity works but hostname access fails, DNS queries, responses or resolver policy may be broken despite healthy network routes. The indicated result—the client resolves the intended address using the approved DNS server and connects using the application hostname—checks a different mechanism and would not confirm the required OSPF prefix advertisement omission outcome.

That result—Both peers enter Full adjacency and exchange the expected route information—concerns OSPF neighbor area mismatch. OSPF requires compatible area identity, network type and essential adjacency parameters; IP reachability alone does not establish a neighbor. It can be healthy even while the current OSPF prefix advertisement omission problem remains.

This would validate RADIUS server reachability, not OSPF prefix advertisement omission. A silent RADIUS transport failure prevents normal authentication regardless of whether the user certificate or role rules are correct. It is therefore insufficient acceptance evidence for the reported condition.

That result—The authorization matrix maps identity conditions to effective user roles and confirms forbidden access is denied—concerns role-based access decisions. Successful authentication proves identity; separate authorization decisions determine permitted destinations, services and segmentation. It can be healthy even while the current OSPF area design problem remains.

A functional hierarchy clarifies where endpoints attach, where traffic aggregates and where policy or Layer 3 boundaries belong. The indicated result—the low-level topology labels uplink capacity, device roles, VLAN boundaries and redundant forwarding paths—checks a different mechanism and would not confirm the required OSPF area design outcome.

This would validate VSF versus VSX platform planning, not OSPF area design. 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.

VSF forms a virtual switch with supported stacking members; VSX coordinates two peers while retaining separate control planes, so support and failure domains differ. The indicated result—the selected hardware and architecture documentation match the intended stacking or peer-control behavior and supported model family—checks a different mechanism and would not confirm the required routing and VRF separation outcome.

That result—The routing plan lists area IDs, required adjacencies and backbone connectivity for each OSPF participating link—concerns OSPF area design. Area design controls link-state information distribution, and nonbackbone areas normally connect through Area 0 via appropriate routers. It can be healthy even while the current routing and VRF separation problem remains.

This would validate directional antenna selection, not routing and VRF separation. 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.

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 firmware-induced configuration drift. That change would leave the actual requirement unresolved.

The alternative targets central API unauthorized response, where 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 establish the intended firmware-induced configuration drift behavior described in the scenario.

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 firmware-induced configuration drift condition.

This would validate acceptance of WLAN security and mobility, not RADIUS service resilience. 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 compatibility matrix references the correct device families and supported release before installation begins—concerns firmware feature-support planning. Product capabilities and configuration syntax depend on supported hardware and software releases; a feature described in another model's guide may be unavailable. It can be healthy even while the current RADIUS service resilience problem remains.

Area design controls link-state information distribution, and nonbackbone areas normally connect through Area 0 via appropriate routers. The indicated result—the routing plan lists area IDs, required adjacencies and backbone connectivity for each OSPF participating link—checks a different mechanism and would not confirm the required RADIUS service resilience outcome.

That result—Representative clients can reach their configured gateways and only permitted inter-VLAN routes operate—concerns SVI inter-VLAN gateway. VLAN configuration creates Layer 2 separation; inter-subnet communication requires appropriate Layer 3 interfaces, addressing and policy. It can be healthy even while the current WPA3 and legacy clients problem remains.

This would validate MAC authentication for headless devices, not WPA3 and legacy clients. MAC authentication can support devices without a supplicant but is weaker than cryptographic identity, so narrow policy and inventory are essential. It is therefore insufficient acceptance evidence for the reported condition.

Wireless association is only the first hop; downstream tunnel, VLAN and gateway mappings must agree for application access. The indicated result—a client on the SSID receives the expected address and the mapped traffic follows the intended path to permitted destinations—checks a different mechanism and would not confirm the required WPA3 and legacy clients outcome.

The alternative targets access/distribution hierarchy, where a functional hierarchy clarifies where endpoints attach, where traffic aggregates and where policy or Layer 3 boundaries belong. It does not establish the intended failure-domain isolation behavior described in the scenario.

That action—Specify guest identity, addressing and policy isolation before enabling the guest WLAN—is relevant to guest network isolation requirements. An SSID name is not a security boundary; guest users need controlled authorization and routes that limit access to internal resources. It does not correct the observed failure-domain isolation condition.

Area design controls link-state information distribution, and nonbackbone areas normally connect through Area 0 via appropriate routers. Plan OSPF area boundaries and backbone reachability before implementing neighbors. would address OSPF area design, but the reported facts instead point to failure-domain isolation. That change would leave the actual requirement unresolved.

That result—The signed acceptance matrix associates each campus requirement with a measurable test, expected result and responsible owner—concerns campus requirements and acceptance criteria. 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 can be healthy even while the current change-window and rollback requirements problem remains.

This would validate critical application traffic profile, not change-window and rollback requirements. Real-time applications can fail with adequate average throughput when contention increases delay or jitter; requirement gathering must distinguish traffic classes. It is therefore insufficient acceptance evidence for the reported condition.

Aggregate access capacity, application demand and supported congestion tolerance determine uplink sizing; port counts alone do not. The indicated result—the projected and tested peak traffic remains within the chosen uplink design's acceptable utilization and loss bounds—checks a different mechanism and would not confirm the required change-window and rollback requirements outcome.
