 | PCIe bandwidth oversubscription | Compares aggregate NIC link rates to slot/PCIe lane capacity; oversubscription can cause throttling and inconsistent performance under load. |
 | Unstable (flapping) adapters | Flags frequent link resets or drops that trigger failovers, raise latency, and degrade throughput before workload impact escalates. |
 | Inbox (unsupported) production drivers | Identifies NICs that use only basic inbox drivers lacking advanced offloads and optimizations, increasing reliability and performance risk. |
-| Aging or out‑of‑date drivers | Assesses driver package age and surfaces early maintenance needs. Warns when a driver is more than two years old so you can plan an update. Network HUD escalates warnings to a fault when a driver exceeds three years of age. |
+| Aging or out‑of‑date drivers | Assesses driver package age and surfaces early maintenance needs. Warns when a driver is more than one year old so you can plan an update. |
 | Driver version inconsistency | Detects mismatched versions across identical adapters, preventing asymmetric behavior, and unpredictable performance. |
 | LLDP operational status | Indicates LLDP packet absences or parsing failure, reducing physical switch link detection and degrading other fabric validation tests. |
 | Misconfigured or inconsistent VLANs | Compares advertised versus expected VLANs across the same-host intent members, the same intent across all hosts, and against the required workload (VM NIC) VLAN availability. Deviations risk VM connectivity loss or storage isolation failure. VLAN consistency across three discrete scopes to catch localized misconfiguration before it becomes a cluster issue: Same-host intent scope: Relevant switchports must advertise the same VLAN set to each adapter in the same Network ATC intent on a single host. Cluster intent scope: All switchports must advertise a consistent VLAN set to adapters in the same Network ATC intent across every host in the cluster. Workload availability scope: VLANs required for all compute workloads (VM NICs) must be advertised to each adapter participating in the same Network ATC intent on every host. |
