If I were to say that you could:
- Identify BGP peering instability;
- Spot Single Points of Failure;
- Verify end-to-end QoS
- Track down OSPF area inconsistencies
- Align FHRP and Spanning Tree
- Troubleshoot multicast forwarding
- Look for firewall bypass scenarios
- Identify 802.1X configuration issues
- Find end-of-life equipment
- Spot where users are having wireless woes
and without having to write Python scripts, Ansible playbooks and DIY, what would you say?
