Troubleshooting APIC ACI Show Command Issues

When show commands on an APIC in Cisco ACI fail to produce output, it often points to underlying issues that require careful analysis. Here are some potential causes and solutions:

1. Authentication or Session Timeout: Ensure your session is active and authenticated. Re-login if needed.
2. Insufficient User Privileges: Verify the account's role; it must have the necessary permissions to execute commands.
3. Database Sync or Resource Constraints: The APIC database might be experiencing sync issues. Try reloading the APIC if faults persist.
4. High CPU or System Faults: Check system health (acidiag avread) and address any detected faults.
5. Fabric Connectivity Problems: Verify fabric health (show fabric nodes) and ensure nodes are reachable.
