The 911 compute cluster will carry Geneve overlay, but the N-VDS still uses a 1500-byte MTU. What should be configured before relying on later DFW or Traceflow results?
Select an answer to reveal the explanation.
Short Explanation
Geneve is extra wrapping on every box; a 1500-byte door shreds the package. Bump host-switch and underlay MTU first so later DFW or Traceflow is not a wild-goose chase for a simple size problem.
Full Explanation
NSX-T overlay uses Geneve, which adds encapsulation overhead that does not fit a 1500-byte path. Configuring jumbo or otherwise increased MTU on the N-VDS or VDS and the physical underlay is part of a working transport-node setup. Distributed firewall does not pad that overhead away. Treating every drop as a DFW miss hides an MTU preparation defect.
