  • 网卡添加VLAN TAG


    #modprobe 8021q 用命令 lsmod | grep 8021q 来检查

    以配置网卡eth0为例,添加vlan号:1002
    =========================================

    cd /etc/sysconfig/network-scripts/
    vi ifcfg-eth0
    把IP地址信息删掉,将ONBOOT设置为yes,将BOOTPROTO设置为none。NM_CONTROLLED改为no。
    ONBOOT=yes
    NM_CONTROLLED=no
    BOOTPROTO=none
    ===========================================

    #vconfig add eth0 1002 1002为vlan号,根据实际vlan配置 通过命令 ls /proc/net/vlan 查看

    =============================================
    cp ifcfg-eth0 ifcfg-eth0.1002
    vi ifcfg-eth0.1003 配置IP信息。

    修改DEVICE=eth0.1003
    IPADDR=10.128.3.116
    NETMASK=255.255.255.0

    最后重启network,service network restart
    测试一下:
    ifconfig查看ifcfg-eth0.1003网卡配置是否正确
    ping下光口地址对应的网关:
    ping 10.128.3.254


    =====================================================

    两个网段:
    B列的服务器:10.128.2.0 vlan: 1002


    C列的服务器:10.128.3.0 vlan: 1003


    -------------------------------------------------------------------------------------------

    -----------------------------------------------------------------------------------------------
    命令:
    modprobe 8021q
    vconfig add eth0 1003
    cd /etc/sysconfig/network-scripts/
    echo modprobe 8021q >> /etc/rc.local
    echo vconfig add eth0 1003 >> /etc/rc.local
    cd /etc/sysconfig/network-scripts/
    sed -i "s/ONBOOT=no/ONBOOT=yes/g" ifcfg-eth0
    sed -i "s/NM_CONTROLLED=yes/NM_CONTROLLED=no/g" ifcfg-eth0
    sed -i "s/BOOTPROTO=dhcp/BOOTPROTO=none/g" ifcfg-eth0
    cp ifcfg-eth0 ifcfg-eth0.1003
    vi ifcfg-eth0.1003

    service network restart
