• 如果集群已加载二层网络，但物理机不存在此二层设备，则物理机不能添加进入对应集群。
• 如果集群未加载二层网络，但物理机不存在此二层设备，则集群不能加载此二层网络。
• 如果某物理机存在此二层设备，但设备接线与集群内其他物理机接线不一致，则创建出的云主机IP不能正常工作。
• 删除二层网络，其对应的子资源三层网络将被删除，使用此三层网络的云主机的网卡也将被删除，请慎重操作。
• 删除二层网络，会删除使用此二层网络的VPC路由器和路由器规格。
• 删除公有网络对应的二层网络，其对应的路由器的一切服务均会被删除，包括VPC路由器、路由器规格、虚拟IP、弹性IP、端口转发、负载均衡、IPsec隧道、NetFlow等。
• 一个VXLAN Pool可以创建多个VxlanNetwork，这些VxlanNetwork可以分别应用于扁平网络或VPC网络。
• VxlanNetwork下的云主机无法被外部的网络直接访问，需要通过弹性IP或者端口转发等服务进行间接访问。
• 一个二层网络可用于创建多个三层网络，但若非特殊业务需求，不推荐多个三层网络共用一个二层网络，否则可能出现DHCP服务不可用的情况。
