The global router MTU configuration is bigger than MTU of switches in overlay Transport Zone which connects to Tier0 or Tier1. Global router MTU value should be less than all switches MTU value by at least a 100 as we require 100 quota for Geneve encapsulation. Action required: 1. Navigate to System | Fabric | Settings | MTU Configuration Check | Inconsistent on the NSX UI to check more mismatch details. 2. Set the bigger MTU value on switches by invoking the NSX API PUT /api/v1/host-switch-profiles/<host-switch-profile-id> with mtu in the request body, or API PUT /api/v1/global-configs/SwitchingGlobalConfig with physical_uplink_mtu in request body. 3. Or set the smaller MTU value of global router configuration by invoking the NSX API PUT /api/v1/global-configs/RoutingGlobalConfig with logical_uplink_mtu in the request body.
