ubuntu下配置vlan设备
添加vlan设备(如eth4为万兆口)
$ ip link add link eth4 name vlan1000 type vlan id 1000
配置vlan地址,如ceph为192.168.1.0网络
$ ip add addr 192.168.1.xxx(xxx最好和千兆口网络地址一致,避免冲突)
配置设备地址长期生效,写入配置文件
$ cat /etc/network/interfaces
...
auto vlan1000
iface vlan1000 inet static
address 192.168.1.xxx
netmask 255.255.255.0
vlan-raw-device eth4
启动设备
$ ip link set dev eth4 up
$ ip link set dev vlan1000 up
