NSX-TNSX for vSphere 设置中的所有逻辑路由器接口具有相同的 MAC 地址 (02:50:56:56:44:52)。从 NSX-T 3.0.2 开始,您可以在 NSX-T 中更改该地址,以避免在将虚拟机从 NSX for vSphere 设置迁移到 NSX-T 设置时出现问题。

更改 MAC 地址涉及进行两次 API 调用。

如果尚未创建任何传输节点,请进行以下 GET API 调用。例如:
GET https://10.40.79.126/api/v1/global-configs/RoutingGlobalConfig

Response:
{
  "l3_forwarding_mode" : "IPV4_ONLY",
  "logical_uplink_mtu" : 1500,
  "vdr_mac" : "02:50:56:56:44:77",
  "vdr_mac_nested" : "02:50:56:56:44:52",
  "allow_changing_vdr_mac_in_use" : true,
  "resource_type" : "RoutingGlobalConfig",
  "id" : "49b261fe-f4e4-46ad-958c-da9cb4271e32",
  "display_name" : "49b261fe-f4e4-46ad-958c-da9cb4271e32",
  "_create_user" : "system",
  "_create_time" : 1595313890595,
  "_last_modified_user" : "admin",
  "_last_modified_time" : 1595465694142,
  "_system_owned" : false,
  "_protection" : "NOT_PROTECTED",
  "_revision" : 14
}
获取该调用的响应,更改 vdr_mac 值,然后使用它进行以下 PUT API 调用。例如:
PUT  https://10.40.79.126/api/v1/global-configs/RoutingGlobalConfig
{
  "l3_forwarding_mode" : "IPV4_ONLY",
  "logical_uplink_mtu" : 1500,
  "vdr_mac" : "02:50:56:56:44:99",
  "vdr_mac_nested" : "02:50:56:56:44:53",
  "allow_changing_vdr_mac_in_use" : true,
  "resource_type" : "RoutingGlobalConfig",
  "id" : "49b261fe-f4e4-46ad-958c-da9cb4271e32",
  "display_name" : "49b261fe-f4e4-46ad-958c-da9cb4271e32",
  "_create_user" : "system",
  "_create_time" : 1595313890595,
  "_last_modified_user" : "admin",
  "_last_modified_time" : 1595465694142,
  "_system_owned" : false,
  "_protection" : "NOT_PROTECTED",
  "_revision" : 14
}

Response:
{
  "l3_forwarding_mode" : "IPV4_ONLY",
  "logical_uplink_mtu" : 1500,
  "vdr_mac" : "02:50:56:56:44:99",
  "vdr_mac_nested" : "02:50:56:56:44:53",
  "allow_changing_vdr_mac_in_use" : true,
  "resource_type" : "RoutingGlobalConfig",
  "id" : "49b261fe-f4e4-46ad-958c-da9cb4271e32",
  "display_name" : "49b261fe-f4e4-46ad-958c-da9cb4271e32",
  "_create_user" : "system",
  "_create_time" : 1595313890595,
  "_last_modified_user" : "admin",
  "_last_modified_time" : 1595466163148,
  "_system_owned" : false,
  "_protection" : "NOT_PROTECTED",
  "_revision" : 15
}

如果已创建传输节点,请进行相同的 GET 和 PUT API 调用;所不同的是,对于 PUT 调用,请将 allow_changing_vdr_mac_in_use 参数设置为 true
