Cisco IOS-XE / NX-OS Device Health Check

Structured triage procedure for assessing Cisco device health across IOS-XE and NX-OS platforms. Produces a prioritized findings report with severity classifications and recommended actions.

Commands are labeled [IOS-XE] or [NX-OS] where they diverge. Unlabeled commands work on both platforms.

When to Use

• Device reported as slow, dropping traffic, or unresponsive
• Scheduled health audit of IOS-XE routers/switches or Nexus platforms
• Post-change verification after upgrades, patches, or configuration changes
• Capacity planning data collection for CPU, memory, and link utilization
• Incident response when a Cisco device is suspected as the fault domain
• NX-OS VDC isolation troubleshooting — health check scoped to a specific VDC
