Products

Issue/Introduction

• In read mode, the problematic segment shows "NotSet" for connectivity and multicast routing field.
• In edit mode, if we click on edit, the same fields appear green/enabled.
• The segment is still functional, and connected workload VMs will not face any issues.

• Running the segment API call: GET https://<nsx-manager>/policy/api/v1/infra/segments/<segment>
• The advanced_config section is missing in the problematic segment when compared to a working segment.

  "advanced_config": {
        "address_pool_paths": [],

        "multicast": true,
        "inter_router": false,
        "local_egress": false,
        "urpf_mode": "STRICT",
        "connectivity": "ON"
    }

Cause
