Diagnose and fix CLOS fabric outages with clear, proven steps that work under pressure.
Modern spine leaf networks fail in subtle ways. Packet loss appears only at peak, EVPN routes look healthy while traffic stalls, and small policy differences ripple across tenants. This guide gives you a practical method to separate signal from noise, collect hard evidence, and apply the smallest fix that restores service.
You get a vendor neutral playbook grounded in production incidents. Nearly every chapter ends with a real scenario that mirrors field conditions, and a full final chapter concentrates complex multi issue cases so you can practice end to end diagnosis under realistic constraints.
- confirm underlay health with MTU headroom checks, ECMP adjacency validation, and bfd symmetry
- stabilize evpn by reading type 2, type 3, and type 5 routes, route targets, and mac mobility sequences
- verify vxlan nve peers, per vni state, anycast gateway consistency, and overlay oam results
- spot and correct route reflector issues including next hop behavior and add path settings
- find ecmp polarization and fix distribution with hash seed changes and inner header hashing
- measure queue health with ecn marks, pfc counters, and per queue drops to remove guesswork
- translate app complaints into packet signals using socket rtt, retransmissions, and short captures
- resolve multi tenant leaks by auditing route targets, vni mapping, and vrf import or export policy
- run safe, focused labs with containerlab and frr or ceos to reproduce failures and prove fixes
- work through full scenarios, underlay loss after maintenance, evpn instability post upgrade, ecmp plus performance regressions, cross vrf outages, post migration slowdowns, and intermittent fabric instability
This is a code heavy guide, with working command sequences and small scripts that collect snapshots, generate traffic, and verify outcomes on real devices.
