/lib/modules/3.10.0-229.14.1.el7.x86_64/kernel/net/8021q/8021q.ko
或者:
[root@controller ~]# modprobe --first-time 8021q
modprobe: ERROR: could not insert '8021q': Module already in kernel
2.如果没有加载802.1q模块怎么加载?
##加载8021q模块
[root@controller ~]# modprobe 8021q
##查看是否正常加载
[root@controller ~]# lsmod |grep 8021q
8021q 28808 0
garp 14384 1 8021q
mrp 18542 1 8021q
3.在父接口创建vlan子接口
3.1在父接口
/etc/sysconfig/network-scripts/ifcfg-ethX
中设置
DEVICE=ethX
TYPE=Ethernet
BOOTPROTO=none
ONBOOT=yes
3.2复制父接口并修改接口名称
cp/etc/sysconfig/network-scripts/ifcfg-ethX
/etc/sysconfig/network-scripts/ifcfg-ethX.125 ## X后面的125为vlan号
3.3配置/etc/sysconfig/network-scripts/ifcfg-ethX.125
DEVICE=ethX.192
BOOTPROTO=none
ONBOOT=yes
IPADDR=192.168.1.1
PREFIX=24
NETWORK=192.168.1.0
VLAN=yes ##开启vlan,表明此子接口为vlan接口
4.重启网络
systemctl restart network
8021q
module is loaded by default. If necessary, you can make sure that the module is loaded by issuing the following command as root
:
~]#modprobe --first-time 8021q
modprobe: ERROR: could not insert '8021q': Module already in kernel
To display information about the module, issue the following command:
~]$ modinfo 8021q
See the modprobe(8)
man page for more command options.
7.4.1. Setting Up 802.1Q VLAN Tagging Using ifcfg Files
- Configure the parent interface in
/etc/sysconfig/network-scripts/ifcfg-ethX
, whereX is a unique number corresponding to a specific interface, as follows:DEVICE=ethX
TYPE=Ethernet
BOOTPROTO=none
ONBOOT=yes - Configure the VLAN interface configuration in the
/etc/sysconfig/network-scripts/
directory. The configuration file name should be the parent interface plus a.
character plus the VLAN ID number. For example, if the VLAN ID is 192, and the parent interface is eth0, then the configuration file name should beifcfg-eth0.192
:DEVICE=ethX.192
BOOTPROTO=none
ONBOOT=yes
IPADDR=192.168.1.1
PREFIX=24
NETWORK=192.168.1.0
VLAN=yesIf there is a need to configure a second VLAN, with for example, VLAN ID 193, on the same interface, eth0, add a new file with the nameeth0.193
with the VLAN configuration details. - Restart the networking service in order for the changes to take effect. As
root
issue the following command:~]#
systemctl restart network
7.4.2. Configure 802.1Q VLAN Tagging Using ip Commands
8
, issue a command as root
as follows:
~]# ip link add link eth0 name eth0.8 type vlan id 8
To view the VLAN, issue the following command:
~]$ip -d link show eth0.8
4: eth0.8@eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP mode DEFAULT
link/ether 52:54:00:ce:5f:6c brd ff:ff:ff:ff:ff:ff promiscuity 0
vlan protocol 802.1Q id 8 <REORDER_HDR>
0x
and as an octal value if it has a leading 0
. This means that in order to assign a VLAN ID with a decimal value of 22
, you must not add any leading zeros.root
as follows:
ip link delete eth0.8
DEVICE=${SECONF_ETH}.${EXTERNAL_TENANT_NETWORK_VLAN_ID}
BOOTPROTO=none
ONBOOT=yes
IPADDR=${SECOND_SUB_INTERFACE_IP}
PREFIX=24
NETWORK=${SECOND_SUB_INTERFACE_NET}
VLAN=yes
