Differentiate a legitimate redundant STP blocked port from a physical link failure or topology loop using bridge-state evidence. This action instead applies to STP blocking and topology-loop recognition. STP discards some redundant paths by design; unexpected topology changes and MAC moves suggest a separate fault. It does not directly resolve the controlling requirement. The targeted response is: Identify LAG members that fail to bundle due to system ID, LACP mode, peer-group, speed or VLAN incompatibility. Scenario: A port channel forms but one member is excluded because the negotiated speed differs from the rest.

Roll out switching changes through a representative pilot, dependency validation and site-by-site acceptance instead of an unchecked big-bang change. This action instead applies to Multisite change phasing and blast radius reduction. Staged delivery contains risk and ensures site-specific exceptions are known before full deployment. It does not directly resolve the controlling requirement. The targeted response is: Identify LAG members that fail to bundle due to system ID, LACP mode, peer-group, speed or VLAN incompatibility. Scenario: A port channel forms but one member is excluded because the negotiated speed differs from the rest.

This action instead applies to OSPF route recovery with controlled scope. A broad redistribution change can leak unwanted networks; OSPF repair should target the proven mismatch. It does not directly resolve the controlling requirement. The targeted response is: Identify LAG members that fail to bundle due to system ID, LACP mode, peer-group, speed or VLAN incompatibility. Scenario: A port channel forms but one member is excluded because the negotiated speed differs from the rest.

Use scheduled and validated AOS-CX software maintenance with platform-specific images, checkpoints and supported fallback approach. This action instead applies to Firmware maintenance compatibility and image fallback. Software maintenance must verify active image and network behavior rather than stop at successful upload of a file. It does not directly resolve the controlling requirement. The targeted response is: Validate AOS-CX configuration templates against supported platform variants and preproduction devices before broad rollout. Scenario: A site-specific gateway variable is blank and the template deploys an incomplete SVI to dozens of branches.

Assign untagged client access ports and explicitly required tagged VLANs to uplinks using supported AOS-CX VLAN interface modes. This action instead applies to Access VLAN and trunk allowed-list design. Native or untagged VLAN behavior and tagged VLAN allowance must agree across both ends of a trunk. It does not directly resolve the controlling requirement. The targeted response is: Validate AOS-CX configuration templates against supported platform variants and preproduction devices before broad rollout. Scenario: A site-specific gateway variable is blank and the template deploys an incomplete SVI to dozens of branches.

Archive switch configs with encryption, retention and least-privilege access while avoiding uncontrolled exposure of shared credentials or tokens. This action instead applies to Safe configuration archiving and secret handling. Configuration histories may contain secrets and management details, so backup security is part of switch operations. It does not directly resolve the controlling requirement. The targeted response is: Validate AOS-CX configuration templates against supported platform variants and preproduction devices before broad rollout. Scenario: A site-specific gateway variable is blank and the template deploys an incomplete SVI to dozens of branches.

Inspect checkpoint inventory, startup/running diff, saved exports, backup location, device-specific recovery instructions and access permissions. These checks can help with Configuration checkpoint and rollback retention, but they are not the most discriminating first evidence here. Examine: Inspect local/remote port IDs, system descriptions, LLDP freshness, link MACs and expected cable map. Scenario: A topology dashboard shows a missing link despite an active interface because LLDP is disabled on one peer.

Classify traffic at supported trust boundaries and map DSCP/802.1p markings into queues consistent with the approved policy. This action instead applies to QoS DSCP trust boundary and class mapping. A QoS marking has no guaranteed effect unless the device trusts, classifies and schedules it as intended. It does not directly resolve the controlling requirement. The targeted response is: Apply policing for untrusted ingress excess and shaping where controlled egress pacing is needed, selecting supported switch features. Scenario: A switch is expected to shape traffic on a platform or interface mode without verifying that feature support exists.

Restore only the approved missing VLAN tags and native VLAN relationship at both ends of an uplink, then test representative hosts. This action instead applies to Correct trunk VLAN remediation.

The targeted response is: Apply policing for untrusted ingress excess and shaping where controlled egress pacing is needed, selecting supported switch features. Scenario: A switch is expected to shape traffic on a platform or interface mode without verifying that feature support exists.

Configure queue weights or strict priority carefully so latency-sensitive applications receive service without starving other traffic. This action instead applies to Egress queue scheduling and congestion protection. Strict priority and weighted scheduling have distinct tradeoffs; QoS cannot create capacity beyond physical bandwidth. It does not directly resolve the controlling requirement. The targeted response is: Apply policing for untrusted ingress excess and shaping where controlled egress pacing is needed, selecting supported switch features. Scenario: A switch is expected to shape traffic on a platform or interface mode without verifying that feature support exists.

An agent generates a reproducible actionable alert for the intended degradation without excessive false positives or device load.

Together with: Review model software release notes, platform feature matrix, hardware resource limits and transceiver compatibility. Scenario: A proposal expects an advanced routing protocol on an access model without verifying software support.

Separate OSPF adjacency failure from absent advertised prefixes by inspecting both neighbor state and routing tables. This action instead applies to OSPF neighbor and route missing root cause. OSPF FULL is a control-plane milestone; missing connected networks or rejected LSAs can still prevent reachability. It does not directly resolve the controlling requirement. The targeted response is: Differentiate RADIUS latency and repeated endpoint authentication churn from application packet loss or physical interface faults. Scenario: A bad endpoint image retries 802.1X every few seconds and floods RADIUS request queues.

Separate ISL interruption, keepalive loss and downlink MC-LAG member faults in a VSX pair using peer-state evidence. This action instead applies to VSX peer and keepalive failure symptom isolation. Independent VSX peer control planes require distinct peer communications; ISL and keepalive carry different roles. It does not directly resolve the controlling requirement. The targeted response is: Differentiate RADIUS latency and repeated endpoint authentication churn from application packet loss or physical interface faults. Scenario: A bad endpoint image retries 802.1X every few seconds and floods RADIUS request queues.

Configure the appropriate spanning tree mode and root placement for the Layer 2 topology, then verify alternate-port behavior.

Together with: Inspect VLAN inventory, per-interface native versus tagged behavior, allowed VLANs and peer trunk configuration. Scenario: An access switch carries VLAN 120 locally but does not allow it across the distribution uplink.

Distinguish missing DHCP broadcasts, blocked offers and relay misconfiguration with trust and binding evidence. This action instead applies to DHCP snooping and client boot failure identification. DHCP snooping enforces trust direction; an untrusted legitimate uplink can suppress all clients even with healthy cables. It does not directly resolve the controlling requirement. The targeted response is: Distinguish loss of light or cabling/optic errors from configuration faults using interface and transceiver diagnostics before changing routing policy. Scenario: A fiber uplink remains down after a switch replacement even though both interfaces are enabled.

Document inter-switch, keepalive and upstream links according to the chosen HA topology with distinct failure paths where applicable. This action instead applies to Resilient peer cabling and link map. Redundant links must be physically and logically identified; duplicate cables through one failure point are not independent resilience. It does not directly resolve the controlling requirement. The targeted response is: Distinguish loss of light or cabling/optic errors from configuration faults using interface and transceiver diagnostics before changing routing policy. Scenario: A fiber uplink remains down after a switch replacement even though both interfaces are enabled.

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: Integrate the network with approved Central monitoring and incident workflows using supported device enrollment, health data and role-scoped access. Scenario: A core switch repeatedly changes uplink status but operations has not configured alert delivery to the correct on-call group.

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.
