The alternative targets VRF route-context configuration, where routes and interfaces are looked up within the relevant VRF; a default route in a different table cannot repair a missing path. It does not establish the intended static route and next-hop reachability behavior described in the scenario.

VLAN configuration creates Layer 2 separation; inter-subnet communication requires appropriate Layer 3 interfaces, addressing and policy. Configure the required VLAN interfaces and routed gateway paths for intended inter-VLAN communication. would address SVI inter-VLAN gateway, but the reported facts instead point to static route and next-hop reachability. That change would leave the actual requirement unresolved.

That action—Ensure SSID VLAN or role forwarding matches the actual bridge or gateway transport design—is relevant to SSID-to-forwarding path consistency. Wireless association is only the first hop; downstream tunnel, VLAN and gateway mappings must agree for application access. It does not correct the observed static route and next-hop reachability condition.

The alternative targets uplink bandwidth capacity, where aggregate access capacity, application demand and supported congestion tolerance determine uplink sizing; port counts alone do not. It does not establish the intended access/distribution hierarchy behavior described in the scenario.

The 2.4 GHz band has limited nonoverlapping channel choices in typical regulatory domains, so channel overlap and wide channels intensify contention. Use appropriately separated 2.4 GHz channels and narrow channel widths for dense coverage. would address 2.4 GHz interference planning, but the reported facts instead point to access/distribution hierarchy. That change would leave the actual requirement unresolved.

That action—Select VSF or VSX based on supported switch family and the required control-plane model—is relevant to VSF versus VSX platform planning. 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 correct the observed access/distribution hierarchy condition.

That result—The approved compatibility matrix and staged test confirm dependent components function on the selected release set—concerns firmware compatibility dependency. Release-specific feature and compatibility constraints can break management or forwarding despite a successful image installation. It can be healthy even while the current AAA change coordination problem remains.

Counters are most useful when compared with known normal operating behavior and collection intervals rather than isolated snapshots. The indicated result—time-series telemetry shows documented normal ranges and highlights material changes from the baseline—checks a different mechanism and would not confirm the required AAA change coordination outcome.

This would validate configuration backup before changes, not AAA change coordination. 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.

Successful authentication proves identity; separate authorization decisions determine permitted destinations, services and segmentation. Define explicit identity-to-role and role-to-policy mappings for campus clients. would address role-based access decisions, but the reported facts instead point to roaming voice coverage overlap. That change would leave the actual requirement unresolved.

The alternative targets high-density channel-width choice, where wider channels can raise peak link rates in isolation yet reduce the number of independent channels available in dense environments. It does not establish the intended roaming voice coverage overlap behavior described in the scenario.

That action—Choose antenna pattern and placement for the coverage geometry and client distribution—is relevant to directional antenna selection. Directional gain shapes energy into target areas and can reduce unwanted spill, but a poorly aimed directional antenna creates coverage holes elsewhere. It does not correct the observed roaming voice coverage overlap condition.

That action—Optimize cell sizing, channel reuse and client load distribution for crowded WLAN areas—is relevant to high-density WLAN airtime optimization. Wireless capacity depends on shared airtime and contention as well as signal quality; excessive power can enlarge overlap without adding usable spectrum. It does not correct the observed roaming voice latency condition.

Non-802.11 emitters can occupy channel energy without appearing as normal Wi-Fi neighbors; channel changes or source mitigation need measured evidence. Use RF spectrum evidence to locate and mitigate non-Wi-Fi interference. would address interference spectrum diagnosis, but the reported facts instead point to roaming voice latency. That change would leave the actual requirement unresolved.

The alternative targets storm control tuning, where overly aggressive limits can discard necessary discovery traffic, while absent protection permits broadcasts to overwhelm forwarding capacity. It does not establish the intended roaming voice latency behavior described in the scenario.

That result—Consumption and service-quality metrics improve outside peak hours without violating coverage or capacity objectives—concerns energy and utilization efficiency. Right-sized operation reduces unnecessary resource use, but energy or capacity savings must not remove availability when users actually need the network. It can be healthy even while the current optimization with rollback problem remains.

A fixed historical baseline can become misleading as workload mix and client capability change; thresholds should reflect current accepted operating conditions. The indicated result—the revised performance baseline includes recent peak usage and documented changes to client mix, application load and network capacity—checks a different mechanism and would not confirm the required optimization with rollback outcome.

This would validate legacy low-rate airtime overhead, not optimization with rollback. Low PHY data rates use more airtime per transmitted bit; rate changes must be constrained by coverage and device support. It is therefore insufficient acceptance evidence for the reported condition.

Accurate time supports certificate validation, event correlation and change records; unsynchronized clocks obscure cause and effect. Synchronize campus network and identity systems to approved time sources. would address NTP clock alignment, but the reported facts instead point to SNMP monitoring scope. That change would leave the actual requirement unresolved.

That action—Correlate related monitoring events and route prioritized alerts to appropriate responders—is relevant to alert correlation and noise reduction. Dependency-aware grouping prevents alert floods from hiding the primary failure and makes operational response more focused. It does not correct the observed SNMP monitoring scope condition.

The alternative targets syslog event centralization, where centralized time-stamped records preserve context for multi-device analysis and avoid relying on volatile local event buffers. It does not establish the intended SNMP monitoring scope behavior described in the scenario.

That result—The requirements document includes per-application targets that can be checked in QoS and performance tests—concerns critical application traffic profile. Real-time applications can fail with adequate average throughput when contention increases delay or jitter; requirement gathering must distinguish traffic classes. It can be healthy even while the current address pool capacity problem remains.

This would validate dual-homed downstream aggregation, not address pool capacity. Hardware redundancy is ineffective if every downstream path still depends on one forwarding node or unsound Layer 2 topology. It is therefore insufficient acceptance evidence for the reported condition.

Available port count does not establish available power; a switch can have free interfaces while its aggregate PoE budget is exhausted. The indicated result—the bill of materials and live PoE telemetry show that all expected powered endpoints fit within supported budget limits—checks a different mechanism and would not confirm the required address pool capacity outcome.

The alternative targets RADIUS service resilience, where identity services become campus availability dependencies; redundant switches cannot authenticate users when all RADIUS paths fail. It does not establish the intended acceptance of WLAN security and mobility 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 acceptance of WLAN security and mobility. That change would leave the actual requirement unresolved.

That action—Define explicit identity-to-role and role-to-policy mappings for campus clients—is relevant to role-based access decisions. Successful authentication proves identity; separate authorization decisions determine permitted destinations, services and segmentation. It does not correct the observed acceptance of WLAN security and mobility condition.

That result—The powered endpoint runs at its intended mode and PoE usage remains below supported allocation limits—concerns power-over-Ethernet failure. A data VLAN or management group cannot correct a switch power budget that denies the PD enough electrical power. It can be healthy even while the current incorrect RADIUS role result problem remains.

Roaming quality depends on usable overlap and timely client/security transitions; stationary speed tests cannot diagnose roaming interruption. The indicated result—a moving client transitions APs with acceptable interruption duration while retaining approved access—checks a different mechanism and would not confirm the required incorrect RADIUS role result outcome.

This would validate EAP-TLS trust-chain failure, not incorrect RADIUS role result. EAP-TLS relies on a trusted certificate path; successful network reachability does not bypass expired or unknown issuing authorities. 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. The indicated result—the intended radio advertises the configured SSID on a permitted channel visible to supported test clients—checks a different mechanism and would not confirm the required access VLAN misassignment outcome.

That result—The powered endpoint runs at its intended mode and PoE usage remains below supported allocation limits—concerns power-over-Ethernet failure. A data VLAN or management group cannot correct a switch power budget that denies the PD enough electrical power. It can be healthy even while the current access VLAN misassignment problem remains.

This would validate physical layer link fault, not access VLAN misassignment. Repeated link transitions and frame errors point to Layer 1 quality or negotiation rather than an unseen WLAN authentication issue. It is therefore insufficient acceptance evidence for the reported condition.
