ubuntu18以上版本配置网卡vlan子接口以及bond配置

admin · 发表于 2023-6-11 15:01:57

由于ubuntu server 18版本后改了网络配置方法，原来是修改/etc/network/interfaces文件
变成了下面的方式
vim /etc/netplan/00-installer-config.yaml

network:
  ethernets:
ens160: #配置的网卡的名称
   addresses: [192.168.8.38/24] #配置的静态ip地址和掩码
   dhcp4: no #关闭DHCP，如果需要打开DHCP则写yes  或者写成false
   optional: true
   gateway4: 192.168.2.1 #网关地址
   nameservers:
      addresses: [192.168.2.1,114.114.114.114] #DNS服务器地址，多个地址需要用英文逗号分隔
ens192:
   addresses: [192.168.2.125/24]
   dhcp4: no
   optional: true
   gateway4: 192.168.2.1
   nameservers:
      addresses: [192.168.2.1,114.114.114.114]
ens193:
   addresses: [192.168.2.126/24]
   dhcp4: no
   optional: true
   gateway4: 192.168.2.1
   nameservers:
      addresses: [192.168.2.1,114.114.114.114]
  bonds:
bond0:  #配置的bond的名称
   interfaces: #包含网卡的名称
      - ens192
      - ens193
   parameters:
      mode: 802.3ad #网络模式
      mii-monitor-interval: 100
  vlans:
ens160.1:  #子接口
   id: 51
   link: ens160    #连接网卡
   addresses: ["192.168.2.244/24"] #接口IP掩码
   gateway4: 192.168.2.1  #网关地址
  version: 2

应用网络配置
netplan apply

查看网络配置
ip a或者ifconfig

vlans:
   enp2s0f1.3:
      id: 3
      link: enp2s0f1
      addresses: [172.168.19.5/24]
      gateway4: 172.168.19.1
      nameservers:
      addresses: [202.106.0.20,114.114.114.114]

使用NetPlan网络管理工具配置网卡.

1、单网卡配置dhcp获取地址；

root@ubuntu20:~# cat /etc/netplan/00-installer-config.yaml
# This is the network config written by 'subiquity'
network:
  ethernets:
ens3:
   dhcp4: yes
  version: 2

2、配置Bond网卡；

      wl0:
         access-points:
            workplace:
                  auth:
                     key-management: eap
                     method: ttls
                     anonymous-identity: "@internal.example.com"
                     identity: "joe@internal.example.com"
                     password: "v3ryS3kr1t"
         dhcp4: yes

9、配置企业加密网络证书认证；

network:

ethernets:
      enp3s0:
      addresses:
         - 10.100.1.38/24
         - 10.100.1.39/24
      gateway4: 10.100.1.1

11、配置静态路由，路由开销；

network:
version: 2
renderer: networkd
ethernets:
      enp3s0:
      addresses:
         - 9.0.0.9/24
         - 10.0.0.10/24
         - 11.0.0.11/24
      #gateway4:  # unset, since we configure routes below
      routes:
         - to: 0.0.0.0/0
               via: 9.0.0.1
               metric: 100
         - to: 0.0.0.0/0

               via: 11.0.0.1
               metric: 100

12、配置使用NetworkManager作为后端管理服务；

network:
version: 2

13、配置双网卡绑定，mode为active-backup；

network:
version: 2
renderer: networkd
bonds:
      bond0:

         dhcp4: true
bridges:
      br0:
         addresses: [ 10.3.99.25/24 ]
         interfaces: [ vlan15 ]
vlans:
      vlan15:
         accept-ra: no
         id: 15
         link: enp0s25

16、配置多个VLAN标记；

network:

renderer: networkd
ethernets:
      mainif:
         match:
            macaddress: "de:ad:be:ef:ca:fe"
         set-name: mainif
         addresses: [ "10.3.0.5/23" ]
         gateway4: 10.3.0.1
         nameservers:
            addresses: [ "8.8.8.8", "8.8.4.4" ]
            search: [ example.com ]
vlans:
      vlan15:
         id: 15
         link: mainif
         addresses: [ "10.3.99.5/24" ]
      vlan10:
         id: 10
         link: mainif
         addresses: [ "10.3.98.5/24" ]
         nameservers:
            addresses: [ "127.0.0.1" ]
            search: [ domain1.example.com, domain2.example.com ]

17、配置直链路由；

            scope: link
         - to: "::/0"
            via: "2001:cafe:face::1"
            on-link: true

18、配置策略路由；

network:
version: 2
renderer: networkd
ethernets:
      ens3:
         addresses:
         - 192.168.3.30/24
         dhcp4: no
         routes:
         - to: 192.168.3.0/24
               via: 192.168.3.1
               table: 101
         routing-policy:
         - from: 192.168.3.0/24
               table: 101
      ens5:
         addresses:
         - 192.168.5.24/24
         dhcp4: no
         gateway4: 192.168.5.1
         routes:
         - to: 192.168.5.0/24
               via: 192.168.5.1

renderer: networkd
ethernets:
      lo:
         match:
            name: lo
         addresses: [ 7.7.7.7/32 ]

20、Windows dhcp配置参考；

network:
version: 2
ethernets:
      enp3s0:
         dhcp4: yes
         dhcp-identifier: mac

21、配置IP通道；

network:
version: 2
ethernets:
      eth0:
         addresses:
            - 1.1.1.1/24
            - "2001:cafe:face::1/64"
         gateway4: 1.1.1.254
tunnels:
      he-ipv6:
         mode: sit
         remote: 2.2.2.2
         local: 1.1.1.1
         addresses:
            - "2001:dead:beef::2/64"
         gateway6: "2001:dead:beef::1"

22、配置SR-IOV 子网卡

登录后复制
network:
version: 2
ethernets:
      eno1:
         mtu: 9000
      enp1s16f1:
         link: eno1
         addresses : [ "10.15.98.25/24" ]
      vf1:
         match:
            name: enp1s16f[2-3]
         link: eno1
         addresses : [ "10.15.99.25/24" ]

admin · 发表于 2023-6-11 15:25:29

特别说明

关键词 vlan211 与 vlan212 需要手动添加虚拟网口并标记VLAN ID

sudo ip link add link ens3 name vlan211 type vlan id 211
sudo ip link add link ens3 name vlan212 type vlan id 212
该配置用来控制系统不使用该网口作为上网的默认网关，在多网口的环境下控制上网流量的方向。（实践发现不设置上网网关后，入站方向的流量也被屏蔽）
