This would validate wired 802.1X port control, not guest captive-portal flow. 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.

VSF presents supported physical members as a virtual switch while retaining operational requirements for healthy stacking links and member state. The indicated result—the stack reports the expected active members and resilient forwarding across an intended member failure—checks a different mechanism and would not confirm the required guest captive-portal flow 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 guest captive-portal flow problem remains.

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 SSID role and VLAN assignment problem remains.

OSPF adjacency depends on compatible peer parameters and reachable interfaces; a live link is insufficient when control-plane settings disagree. The indicated result—both routers report a stable Full neighbor state and the intended routes appear in the correct routing table—checks a different mechanism and would not confirm the required SSID role and VLAN assignment outcome.

This would validate guest captive-portal flow, not SSID role and VLAN assignment. Association and address assignment alone cannot enforce guest registration or policy acceptance; the portal and post-login role must be connected. It is therefore insufficient acceptance evidence for the reported condition.

Healthy RF and RADIUS reachability cannot compensate for an expired or untrusted certificate that fails the authentication handshake. The indicated result—certificate inventory and alerts show sufficient renewal lead time and successful test authentication after renewal—checks a different mechanism and would not confirm the required firmware rollout staging outcome.

That result—The change ticket links a verified baseline configuration and a tested restoration procedure—concerns configuration backup before changes. Reversible change management requires knowing the previous effective state, not merely retaining a screenshot of intended edits. It can be healthy even while the current firmware rollout staging problem remains.

This would validate baseline interface health metrics, not firmware rollout staging. Counters are most useful when compared with known normal operating behavior and collection intervals rather than isolated snapshots. It is therefore insufficient acceptance evidence for the reported condition.

OSPF requires compatible area identity, network type and essential adjacency parameters; IP reachability alone does not establish a neighbor. Compare OSPF area and interface parameters between the two peers. would address OSPF neighbor area mismatch, but the reported facts instead point to DNS mistaken for routing failure. That change would leave the actual requirement unresolved.

That action—Match OSPF authentication method and key material on the intended neighbors—is relevant to OSPF authentication mismatch. Routing protocol control packets may be rejected when authentication differs, even if underlying Layer 3 ping succeeds. It does not correct the observed DNS mistaken for routing failure condition.

The alternative targets IPv6 router-advertisement spoofing, where IPv4 ARP safeguards do not inspect ICMPv6 router announcements; RA protection constrains unauthorized router information on client segments. It does not establish the intended DNS mistaken for routing failure behavior described in the scenario.

That result—A client on the SSID receives the expected address and the mapped traffic follows the intended path to permitted destinations—concerns SSID-to-forwarding path consistency. Wireless association is only the first hop; downstream tunnel, VLAN and gateway mappings must agree for application access. It can be healthy even while the current route redistribution filters problem remains.

A virtual first-hop gateway provides a stable client next-hop while authorized peers coordinate active forwarding after failure. The indicated result—a peer failure preserves client reachability to the virtual gateway and restores traffic within the approved recovery target—checks a different mechanism and would not confirm the required route redistribution filters outcome.

This would validate multicast receiver handling, not route redistribution filters. IGMP membership information lets switches constrain Layer 2 multicast distribution instead of flooding traffic indiscriminately. It is therefore insufficient acceptance evidence for the reported condition.

The alternative targets RF survey and building materials, where propagation and attenuation vary with walls, shelving and device environments; a diagram alone cannot establish coverage or service quality. It does not establish the intended VSF versus VSX platform planning behavior described in the scenario.

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 VSF versus VSX platform planning condition.

Aggregate access capacity, application demand and supported congestion tolerance determine uplink sizing; port counts alone do not. Model oversubscription and dimension distribution uplinks for peak traffic patterns. would address uplink bandwidth capacity, but the reported facts instead point to VSF versus VSX platform planning. That change would leave the actual requirement unresolved.

This would validate access port VLAN membership, not new Central scoped inheritance. Client frames received untagged are placed in the port's access VLAN; a healthy physical link cannot compensate for wrong Layer 2 membership. It is therefore insufficient acceptance evidence for the reported condition.

Shared templates are reusable only when site-specific identity, address and port data are correctly substituted for each target device. The indicated result—rendered configurations contain the intended unique addresses and device settings with no unresolved placeholder values—checks a different mechanism and would not confirm the required new Central scoped inheritance outcome.

That result—Management endpoint resolution and permitted connectivity tests succeed and the device subsequently establishes cloud management—concerns management connectivity and DNS. Central enrollment requires correctly routed and resolved management traffic; a working user VLAN does not guarantee reachability of the management plane. It can be healthy even while the current new Central scoped inheritance problem remains.

A reliable voice WLAN needs usable signal and timely authentication/roaming behavior between neighboring cells, not maximum isolated AP range. The indicated result—walking-call tests show successful transitions with latency and loss remaining within the voice application's limits—checks a different mechanism and would not confirm the required 2.4 GHz interference planning outcome.

This would validate guest network isolation requirements, not 2.4 GHz interference planning. An SSID name is not a security boundary; guest users need controlled authorization and routes that limit access to internal resources. It is therefore insufficient acceptance evidence for the reported condition.

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 2.4 GHz interference planning problem remains.

That action—Capture application latency, jitter, loss and priority requirements as distinct design constraints—is relevant to 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 does not correct the observed 6 GHz WLAN compatibility condition.

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 6 GHz WLAN compatibility behavior described in the scenario.

A higher RSSI does not remove contention; channel planning, cell sizing and client density are needed to increase effective capacity. Plan enough usable wireless airtime and spatial reuse rather than simply raising transmit power. would address coverage versus capacity tradeoff, but the reported facts instead point to 6 GHz WLAN compatibility. That change would leave the actual requirement unresolved.

That action—Allow required tagged VLANs consistently along the end-to-end trunk path—is relevant to trunk allowed VLAN list. A VLAN's existence on each switch is insufficient if the inter-switch trunk omits it, so frames cannot traverse the missing membership. It does not correct the observed spanning-tree loop prevention condition.

Layer 3 boundaries do not normally forward client DHCP broadcasts without relay behavior; the helper target must also be reachable. Configure DHCP relay on the correct client-facing routed interface where centralized DHCP is used. would address DHCP relay on routed segments, but the reported facts instead point to spanning-tree loop prevention. That change would leave the actual requirement unresolved.

The alternative targets dynamic role enforcement, where a RADIUS Access-Accept alone does not prove the switch or gateway applied the intended role policy to user sessions. It does not establish the intended spanning-tree loop prevention behavior described in the scenario.

That action—Verify compatible link speed, duplex and negotiation settings on both interface ends—is relevant to duplex and speed negotiation. Mismatched physical link parameters can create collisions or errors despite a link-up status, so higher-layer policy changes cannot repair them. It does not correct the observed MAC learning and unintended loops condition.

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 MAC learning and unintended loops. That change would leave the actual requirement unresolved.

The alternative targets firmware-induced configuration drift, where successful reboot and version display do not establish that all intended policies and interface behaviors survived the change. It does not establish the intended MAC learning and unintended loops behavior described in the scenario.
