Use supported Network Analytics Engine monitors and rules to correlate switch database state with alerts and historical graphs. This action instead applies to NAE agent and threshold monitoring. NAE rules evaluate monitored data and can trigger alerts; a script must be enabled and scoped, not merely uploaded. It does not directly resolve the controlling requirement. The targeted response is: Measure routing neighbor uptime, route churn and failover behavior across OSPF or BGP rather than relying on one point-in-time state. Scenario: An OSPF peer displays FULL at inspection time despite ten resets during the previous hour.

Trace a host's local IP, mask, gateway and ARP resolution before attributing reachability failure to routing protocols. This action instead applies to IP addressing subnet and gateway mismatch. Incorrect subnet or default gateway settings can break connectivity even while VLAN forwarding remains healthy. It does not directly resolve the controlling requirement. The targeted response is: Measure routing neighbor uptime, route churn and failover behavior across OSPF or BGP rather than relying on one point-in-time state. Scenario: An OSPF peer displays FULL at inspection time despite ten resets during the previous hour.

Use LLDP neighbor data and interface inventories to verify connected peers and document the physical campus topology. This action instead applies to LLDP topology and neighbor mapping. LLDP is discovery evidence but neighbor advertisements do not prove the entire end-to-end forwarding path is authorized. It does not directly resolve the controlling requirement. The targeted response is: Measure routing neighbor uptime, route churn and failover behavior across OSPF or BGP rather than relying on one point-in-time state. Scenario: An OSPF peer displays FULL at inspection time despite ten resets during the previous hour.

Only intended route entries recover in the correct VRF and failover remains predictable. This step pertains to OSPF route recovery with controlled scope but is not one of the two complementary decisions in this case. The required response and evidence are: Interpret sustained and peak port utilization alongside errors, queue drops and application quality before deciding on upgrades. Together with: Inspect counter rates, monitoring interval, interface speed, burst peaks, growth trend and service-level effects.

This step pertains to Scheduled change window and impact communication but is not one of the two complementary decisions in this case. The required response and evidence are: Interpret sustained and peak port utilization alongside errors, queue drops and application quality before deciding on upgrades. Together with: Inspect counter rates, monitoring interval, interface speed, burst peaks, growth trend and service-level effects. Scenario: An operations dashboard recommends replacing a switch because one single-day graph has a transient peak.

Attribute application loss to the actual congested egress queue and traffic class rather than only interface-level packet drops. This action instead applies to QoS queue drop root cause under congestion. Interface error counters can remain zero while egress queues discard packets during oversubscription. It does not directly resolve the controlling requirement. The targeted response is: Restrict SSH, HTTPS and management VRF exposure and apply individual authenticated administrator roles before enabling remote management. Scenario: Operations loses SSH access after changing the management VLAN with no console fallback plan.

Record deliberate changes in running configuration, save the intended startup state and use checkpoints or diffs as an auditable rollback option. This action instead applies to AOS-CX configuration save and checkpoint workflow. A running change does not become a persistent boot baseline automatically without the appropriate save process. It does not directly resolve the controlling requirement. The targeted response is: Restrict SSH, HTTPS and management VRF exposure and apply individual authenticated administrator roles before enabling remote management. Scenario: Operations loses SSH access after changing the management VLAN with no console fallback plan.

Use the correct AOS-CX interface context and verify administrative state, speed and VLAN mode rather than reusing unrelated switch-vendor syntax. This action instead applies to AOS-CX interface configuration hierarchy. Interface commands operate in specific contexts; correct syntax alone does not confirm that the intended port or mode was changed. It does not directly resolve the controlling requirement. The targeted response is: Restrict SSH, HTTPS and management VRF exposure and apply individual authenticated administrator roles before enabling remote management. Scenario: Operations loses SSH access after changing the management VLAN with no console fallback plan.
