网络计划干扰IP分配？Ubuntu 18.10

Question

我有一个简单的Ubuntu测试床，我遇到了一个非常不寻常的问题。由于某种原因，似乎我的IP地址在没有用户任何干预的情况下在交错之间发生变化，我无法解释它。

下面是我得到的:一台带有Ubuntu18.10Server的机器(宇宙？)通过DHCP静态保留映射到IP 172.16.222.63的1GB接口和静态分配IP 172.16.222.64 (使用ifconfig)的10 1GB接口。此服务器为空白，仅在安装过程中选择OpenSSH。

它是附加到一个惠普Pro弧线2900-48G开关，这是工厂的默认。没有配置或正在运行的VLAN，所有开关端口都是默认的。1GB接口和10 1GB接口作为测试盒附加到此开关上。

从测试盒中，我开始在一个终端窗口中单击172.16.222.63 (1G)，在另一个终端窗口中开始单击172.16.222.64 (10G)。只有1G接口响应。

如果我断开1G接口，10G接口就开始运行。如果我重新连接1G接口，10G接口将停止pinging。

我检查了iptable，没有规则，一切都设置为默认允许。Arp表显示了我的测试框的MAC和默认网关。

上周五，我在中询问了这个问题，尽管症状略有不同。当两个接口都被连接时，两个接口都会进行ping。如果1G接口断开，10G接口将保持可点击，但几分钟后，1G IP地址将开始响应10G接口！重新连接1G接口和断开10G接口将导致两个IP移动到1G接口。

在和我的同事讨论过之后，大家的普遍共识似乎是，网络计划正在引发问题。还有其他人看过这个吗？有什么办法可以解决这个问题，以便IP地址“待在”被分配到的接口上吗？

这样做的全部原因是我将在1G和10G接口上进行一些性能测试，并且我需要能够向这两个接口发送数据。有了它当前的状态，我无法保证通过IP地址将数据发送到正确的接口。

谢谢!

Answer 1

尝试更像这个骨架.yaml文件..。确保没有制表符或额外的空格..。有些地址可能需要调整..。

network:
  version: 2
  renderer: networkd
  ethernets:
    enp3s0:
      addresses: 172.16.222.64/24
      gateway4: 172.16.222.1
      nameservers:
        addresses: [8.8.8.8,8.8.4.4]
    enp4s0:
      dhcp4: no
      dhcp6: no
    enp5s0f0:
      addresses: 172.16.222.63/24
      gateway4: 172.16.222.1
      nameservers:
        addresses: [8.8.8.8,8.8.4.4]
    enp5s0f1:
      dhcp4: no
      dhcp6: no

然后

sudo netplan --debug generate #生成配置文件

sudo netplan apply #激活新配置

reboot #可能是可选的..。重新启动计算机
