(linux) 網卡設定vlan(802.1q)

安裝VLAN(802.1Q)

apt-get install vlan

Load the 8021q kernel module

sudo modprobe 8021q

Ensure that this module gets loaded after a reboot by adding to /etc/modules:

sudo  sh -c 'grep -q 8021q /etc/modules || echo 8021q >> /etc/modules'

替網卡加入VLAN

sudo vconfig add eth0 100
sudo vconfig add <Ether Card> <VID>
sudo vconfig delete <Ether Card> <VID>

設定每個網卡對應VLAN的IP, netmask

sudo ifconfig eth0.100 192.168.100.1 netmask 255.255.255.0
sudo ifconfig eth0.<VID> <IP> netmask 255.255.255.0

測試VLAN是否作用,Ping 192.168.100.1/24,使用wireshark錄eth0封包

永久設定每個網卡對應VLAN的IP, netmask

sudo vim /etc/network/interfaces

auto eth0.100
iface eth0.100 inet static
address 192.168.100.1
netmask 255.255.255.0
