使用bond为物理接口，bond配置可以参考：https://blog.csdn.net/qq_50247813/article/details/143630081
实验一、配置vlan子接口
-
创建bond0，模式为802.3ad；从网卡，ens37，ens38，添加子接口 bond0.10，配置vlanid 10
root@ubuntu22:/etc/netplan# cat bond0.yaml network: version: 2 renderer: networkd ethernets: ens37: addresses: [] dhcp4: no optional: true ens38: addresses: [] dhcp4: no optional: true bonds: bond0: interfaces: [ens37,ens38] parameters: mode: 802.3ad lacp-rate: fast mii-monitor-interval: 100 transmit-hash-policy: layer3+4 vlans: bond0.10: id: 10 link: bond0 addresses: [192.168.1.100/24] routes: - to: 0.0.0.0 via: 192.168.1.1 nameservers: addresses: [114.114.114.114] -
查看子接口和vlan信息
root@ubuntu22:/etc/netplan# netplan apply root@ubuntu22:/etc/systemd# ip addr show bond0.10 6: bond0.10@bond0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000 link/ether 1a:40:de:5e:c3:0c brd ff:ff:ff:ff:ff:ff inet 192.168.1.100/24 brd 192.168.1.255 scope global bond0.10 valid_lft forever preferred_lft forever inet6 fe80::1840:deff:fe5e:c30c/64 scope link valid_lft forever preferred_lft forever root@ubuntu22:/etc/systemd# cat /proc/net/vlan/ bond0.10 config root@ubuntu22:/etc/systemd# cat /proc/net/vlan/config VLAN Dev name | VLAN ID Name-Type: VLAN_NAME_TYPE_RAW_PLUS_VID_NO_PAD bond0.10 | 10 | bond0
实验二、创建网桥
-
正常绑定接口
root@ubuntu22:/etc/netplan# cat br0.yaml network: version: 2 renderer: networkd ethernets: ens37: addresses: [] dhcp4: no optional: true ens38: addresses: [] dhcp4: no optional: true bonds: bond0: interfaces: [ens37,ens38] parameters: mode: 802.3ad lacp-rate: fast mii-monitor-interval: 100 transmit-hash-policy: layer3+4 bridges: br0: interfaces: [bond0] # 将物理接口绑定到网桥 dhcp4: yes # 如果希望通过DHCP获取IP地址 # 如果使用静态IP地址，可以配置如下： # addresses: [192.168.1.100/24] # gateway4: 192.168.1.1 # nameservers: # addresses: [8.8.8.8, 1.1.1.1]查看网桥接口，已经网桥信息

绑定子接口
root@ubuntu22:/etc/netplan# cat br0.yaml network: version: 2 renderer: networkd ethernets: ens37: addresses: [] dhcp4: no optional: true ens38: addresses: [] dhcp4: no optional: true bonds: bond0: interfaces: [ens37,ens38] parameters: mode: 802.3ad lacp-rate: fast mii-monitor-interval: 100 transmit-hash-policy: layer3+4 vlans: bond0.10: id: 10 link: bond0 addresses: [] bridges: br0: interfaces: [bond0.10] dhcp4: no addresses: [192.168.1.100/24] routes: - to: 0.0.0.0 via: 192.168.1.1 nameservers: addresses: [8.8.8.8]这里和配置vlan 子接口配置很像，但是配置网桥，子接口地址就无需要配置，地址配置在网桥上，子接口作为网桥的一个端口。
