18.04 LTS 中的 Netplan 上的 Vlan

免责声明：直到今天，我一直是一个潜水员，仍在学习，这是两年来我第一次没有找到我的问题的答案，非常感谢你的阅读，我希望你能花点时间帮助我

我正在尝试在现有的 LAN 卡上设置两个 VLAN，此设置的目的是先使第一个 VLAN 工作，然后再让所有内容通过不同的 VLAN 用于不同的目的

这是我的配置：

網卡：

cat /etc/netplan/10-enp1s0.yaml network:  version: 2  renderer: networkd  ethernets:
#LAN CARD config
   enp1s0:
     optional: true
     dhcp4: false
     dhcp6: false
     addresses: [192.168.1.91/24, ]
     gateway4: 192.168.1.254
     nameservers:
       addresses: [192.168.1.91, ] //I have a DNS on the server
       search: [domain.net]

虚拟局域网（VLAN）：

cat /etc/netplan/11-vlan.11.yaml
 vlans:
   vlan.11:
     id: 11
     link: enp1s0
     optional: true
     dhcp4: false
     dhcp6: false
     addresses: [192.168.1.92/24, ]
     nameservers:
       addresses: [192.168.1.91, ]

使用此配置，结果如下：

  • 当我尝试从 enp1s0 ping vlan.11 或反之时，我没有得到回复。
  • 当我尝试从 enp1s0 ping 任何互联网时，它可以工作，但是当我尝试使用 vlan.11 时，它不起作用。

8.8.8.8 与 enp1s0：

ping -I enp1s0 8.8.8.8
PING 8.8.8.8 (8.8.8.8) from 192.168.1.91 enp1s0: 56(84) bytes of data.
64 bytes from 8.8.8.8: icmp_seq=1 ttl=57 time=9.24 ms

8.8.8.8 与 vlan.11：

ping -I vlan.11 8.8.8.8
PING 8.8.8.8 (8.8.8.8) from 192.168.1.92 vlan.11: 56(84) bytes of data.
3 packets transmitted, 0 received, 100% packet loss, time 2039ms
  • 最后也是最奇怪的是，我能够使用同一网络上的另一台 PC ping 这两个地址
Pinging 192.168.1.91 with 32 bytes of data: Reply from 192.168.1.91:
bytes=32 time<1ms TTL=64

Pinging 192.168.1.92 with 32 bytes of data: Reply from 192.168.1.92:
bytes=32 time<1ms TTL=64 Reply from 192.168.1.92: bytes=32 time<1ms
TTL=64

那么，您能解释一下为什么我的 VLAN 无法正常工作吗？我缺少什么才能让 VLAN.11 像网卡一样运行。

非常感谢您的阅读，我们非常感谢您的帮助。

当我输入 sudo netplan --debug generate 时，我看到了这个（不要担心 enp2s0，目前尚未配置也未连接）：

sudo netplan --debug generate

答案1

您的.yaml 文件不完整。

你不能”删除我的 LAN 卡配置“。

删除两个 .yaml 文件并尝试此操作...保持相同的间距和缩进，并且没有制表符...

network:
  version: 2
  renderer: networkd
  ethernets:
    enp1s0:
      addresses: [192.168.1.91/24]
      gateway4: 192.168.1.254
      nameservers:
        addresses: 192.168.1.91
        search: [domain.net]
      optional: true
  vlans:
    vlan.11:
      id: 11
      link: enp1s0
      addresses: [192.168.1.92/24]

sudo netplan --debug generate# 生成配置文件

sudo netplan apply# 应用新配置

reboot# 重启计算机

@heynnema：

这是 sudo netplan --debug generate 的输出，我刚刚将 vlan.11 添加到了可选项，因此服务器不会等待 cloud-init

sudo netplan--debug 生成

DEBUG:command generate: running ['/lib/netplan/generate']

我真的希望这能帮助您帮助我解决这个问题，再次感谢您的时间。

问题解决了 ！

而不是 ping 并使用 vlan.11（这是..第 2 层名称？有点像？）

无论如何，直接使用 IP 地址非常有效，简而言之：

ping -I vlan.11 不起作用 ping -I 工作正常！

谢谢你的帮助，希望这对别人有帮助
