Interpret switch resource, interface and protocol snapshots against a known-good baseline and recent change history. This action instead applies to Operational state and baseline configuration differences. A baseline is a set of comparable conditions, not a single healthy green status indicator. It does not directly resolve the controlling requirement. The targeted response is: Validate PoE power supply capacity, cable pairs and endpoint class before activating powered devices or redundant PSU policies. Scenario: A camera fleet appears to have link connectivity but fails at night when infrared features increase power draw.

Prepare DHCP, provisioning endpoint reachability, management VLAN or VRF and initial credentials for safe zero-touch provisioning. This action instead applies to ZTP bootstrapping and management plane reachability. ZTP automates bootstrap only when the required discovery and management dependencies function correctly. It does not directly resolve the controlling requirement. The targeted response is: Validate PoE power supply capacity, cable pairs and endpoint class before activating powered devices or redundant PSU policies. Scenario: A camera fleet appears to have link connectivity but fails at night when infrared features increase power draw.

Configure EAP-based access authentication with correct RADIUS reachability, credentials, switch identity and port role behavior. This action instead applies to 802.1X and RADIUS port authentication. An access port can be physically up but blocked by authentication policy, distinct from VLAN or cabling failure. It does not directly resolve the controlling requirement. The targeted response is: Validate PoE power supply capacity, cable pairs and endpoint class before activating powered devices or redundant PSU policies. Scenario: A camera fleet appears to have link connectivity but fails at night when infrared features increase power draw.

Reconcile the approved design with actual interfaces, optics, firmware, cable labels and final switch configurations after deployment. This action instead applies to Change documentation and as-built reconciliation. The approved design and final operating topology can diverge, requiring documented changes rather than silent drift. It does not directly resolve the controlling requirement. The targeted response is: Use the correct AOS-CX interface context and verify administrative state, speed and VLAN mode rather than reusing unrelated switch-vendor syntax. Scenario: A remediation enables an interface administratively but fails to check whether the attached optic or neighbor can negotiate the expected speed.

Use supported AOS-CX API endpoints and role-scoped service accounts for automations, separating read-only audits from approved changes. This action instead applies to REST API and configuration-tool integration boundaries. API availability, versioning and authorization govern integrations; an HTTP success status must be correlated with network state. It does not directly resolve the controlling requirement. The targeted response is: Use the correct AOS-CX interface context and verify administrative state, speed and VLAN mode rather than reusing unrelated switch-vendor syntax. Scenario: A remediation enables an interface administratively but fails to check whether the attached optic or neighbor can negotiate the expected speed.

Coordinate 802.1X authorization with an approved network access policy platform and verify returned VLAN or role attributes. This action instead applies to ClearPass or identity-service policy integration. An identity server may accept credentials while issuing incorrect network authorization attributes. It does not directly resolve the controlling requirement. The targeted response is: Use the correct AOS-CX interface context and verify administrative state, speed and VLAN mode rather than reusing unrelated switch-vendor syntax. Scenario: A remediation enables an interface administratively but fails to check whether the attached optic or neighbor can negotiate the expected speed.

Review endpoint counts by class, anticipated additions, PoE budgets and uplink utilization peaks. These checks can help with Port density and growth headroom, but they are not the most discriminating first evidence here. Examine: Inspect role download status, authentication result, role mapping, ACL application, device/platform support and enforcement counters. Scenario: A clinic wants colorless ports but a switch never receives the expected downloadable role from the policy server.

Inspect RADIUS server reachability/secret, authentication session state, EAP exchange, assigned role and rejection logs. These checks can help with 802.1X and RADIUS port authentication, but they are not the most discriminating first evidence here. Examine: Inspect role download status, authentication result, role mapping, ACL application, device/platform support and enforcement counters. Scenario: A clinic wants colorless ports but a switch never receives the expected downloadable role from the policy server.

Check endpoint identity, allowed MAC profiles, primary 802.1X attempts, fallback order, authentication timeout and role policy. These checks can help with MAC authentication and critical access fallback, but they are not the most discriminating first evidence here. Examine: Inspect role download status, authentication result, role mapping, ACL application, device/platform support and enforcement counters. Scenario: A clinic wants colorless ports but a switch never receives the expected downloadable role from the policy server.

Check VLAN active members, SVI IP prefix, routing state, VRF membership, connected routes and ARP/ND entries. This step pertains to SVI and routed interface gateway configuration but is not one of the two complementary decisions in this case. The required response and evidence are: Restrict SSH, HTTPS and management VRF exposure and apply individual authenticated administrator roles before enabling remote management. Together with: Check enabled management services by VRF, ACLs, user roles, TLS/SSH settings, logging, NTP and out-of-band recovery. Scenario: A switch uses a shared administrative login even though per-user accountability is required for configuration audits.

The path operates at supported negotiated speed with stable error counters and expected throughput. This step pertains to Duplex speed and physical error performance analysis but is not one of the two complementary decisions in this case. The required response and evidence are: Restrict SSH, HTTPS and management VRF exposure and apply individual authenticated administrator roles before enabling remote management. Together with: Check enabled management services by VRF, ACLs, user roles, TLS/SSH settings, logging, NTP and out-of-band recovery. Scenario: A switch uses a shared administrative login even though per-user accountability is required for configuration audits.

Record deliberate changes in running configuration, save the intended startup state and use checkpoints or diffs as an auditable rollback option. This step pertains to AOS-CX configuration save and checkpoint workflow but is not one of the two complementary decisions in this case. The required response and evidence are: Restrict SSH, HTTPS and management VRF exposure and apply individual authenticated administrator roles before enabling remote management. Together with: Check enabled management services by VRF, ACLs, user roles, TLS/SSH settings, logging, NTP and out-of-band recovery. Scenario: A switch uses a shared administrative login even though per-user accountability is required for configuration audits.

Confirm required AOS-CX capabilities against exact switch series and firmware before committing to routing, overlays or security services. This action instead applies to AOS-CX feature and software compatibility matrix. AOS-CX is a software family but not every feature is universal across all product series and releases. It does not directly resolve the controlling requirement. The targeted response is: Use approved MAC authentication or critical-role treatment for devices lacking supplicants with explicit limited privileges and monitoring. Scenario: When RADIUS is unreachable every device receives an unrestricted role, defeating the site's isolation policy.

Apply group-level switching policies only after confirming device model compatibility and whether the site is UI-group or template-group managed. This action instead applies to Central UI group versus template configuration scope. Template and UI group management workflows are not interchangeable, especially for device-specific variable substitution. It does not directly resolve the controlling requirement. The targeted response is: Use approved MAC authentication or critical-role treatment for devices lacking supplicants with explicit limited privileges and monitoring. Scenario: When RADIUS is unreachable every device receives an unrestricted role, defeating the site's isolation policy.

Create LAG groups with matching LACP negotiation, physical rates, VLAN configuration and supported hash behavior. This action instead applies to LACP link aggregation member consistency. LACP forms an aggregate only when the peer and member attributes are compatible; wiring two cables is not proof of bundling. It does not directly resolve the controlling requirement. The targeted response is: Use approved MAC authentication or critical-role treatment for devices lacking supplicants with explicit limited privileges and monitoring. Scenario: When RADIUS is unreachable every device receives an unrestricted role, defeating the site's isolation policy.
