Symptom & Impact

Automated network changes fail and revert, delaying provisioning tasks.

Environment & Reproduction

Seen with invalid YAML or unsupported NIC properties.

nmstatectl show
nmstatectl apply /tmp/state.yaml

Root Cause Analysis

Desired state conflicts with device capabilities or existing connection constraints.

Quick Triage

Validate syntax and inspect generated NetworkManager profiles.

nmstatectl gc /tmp/state.yaml
nmcli connection show

Step-by-Step Diagnosis

Review nmstate and NetworkManager logs for transaction error details.

journalctl -u NetworkManager -n 200 --no-pager
journalctl -t nmstate -n 120 --no-pager

Solution – Primary Fix

Fix invalid attributes and apply in checkpoint mode first.

Solution – Alternative Approaches

Apply incremental interface changes with nmcli when full-state apply is risky.

nmcli connection modify  ipv4.addresses 10.0.10.20/24

Verification & Acceptance Criteria

Desired interface, IP, and route state remains stable post-apply.

ip -br addr
ip route

Rollback Plan

Reapply known-good state file if connectivity regresses.

nmstatectl apply /root/known-good.yaml

Prevention & Hardening

Use staged validation in CI before production network changes.

nmstatectl gc /root/planned.yaml
nmstatectl show

verification failed, rollback triggered, unsupported interface setting.
