Linux 绑定 VLAN 问题

Question

您认为以下配置有意义吗？是否BONDTING_OPT支持 VLAN 接口？我想确保我的接口在上游设备关闭时进行故障转移。

ifcfg-bond0

$ cat /etc/sysconfig/network-scripts/ifcfg-bond0
NAME=bond0
DEVICE=bond0
BOOTPROTO=none
ONBOOT=yes
BONDING_OPTS="mode=1 miimon=500 downdelay=1000 primary=eno1 primary_reselect=always"

ifcfg-bond0.10

$ cat /etc/sysconfig/network-scripts/ifcfg-bond0.10
NAME=bond0.10
DEVICE=bond0.10
ONPARENT=yes
BOOTPROTO=dhcp
VLAN=yes
BONDING_OPTS="mode=1 arp_interval=1000 arp_ip_target=10.10.0.1 miimon=500 downdelay=1000 primary=eno1 primary_reselect=always"
NM_CONTROLLED=no

ifcfg-bond0.20

$ cat /etc/sysconfig/network-scripts/ifcfg-bond0.20
NAME=bond0.20
DEVICE=bond0.20
ONPARENT=yes
BOOTPROTO=dhcp
VLAN=yes
BONDING_OPTS="mode=1 arp_interval=1000 arp_ip_target=74.xx.xx.1 miimon=500 downdelay=1000 primary=eno1 primary_reselect=always"
NM_CONTROLLED=no

Answer 1

您需要配置设备，然后是绑定，最后是 VLAN 配置文件。您还必须注意哪些属性在何处起作用，例如bonding_opts，它只能在bond 本身中，而不是VLAN 配置文件，因为VLAN 文件将无法直接访问以太网连接。

我还发现了这个 RHEL 6 文档，它对其进行了更多解释。它对于 RHEL 7 / CentOS 7 来说仍然是最可靠的。

• 在绑定上配置 VLAN

添加：

绑定负责管理绑定使用的物理连接。如下面的驱动程序输出所示，VLAN 无法看到物理连接；他们只看到负责他们的设备，在这种情况下，bond0。

还在这里解释了另一个观点： bonded-and-primary-virtual-ip-addresses-and-vlan-tagged 答案

笔记：

• 我知道这很有效，因为我在 RHEL 7 系统上使用它。
• 如果您需要更多 VLAN，只需cp ifcfg-bond0.20 ifcfg-bond0.30更新必填字段。

图表：

eth0         vlan1
    \       / 
      bond0 -vlan2
    /       \
eth1         vlan3

例子：

[工作配置]

 ==> ifcfg-eth0 <==
 DEVICE=eth0
 NAME=bond0-slave
 HWADDR=xx:xx:xx:xx:xx:xx
 ONBOOT=yes
 BOOTPROTO=none
 MASTER=bond0
 SLAVE=yes
 USERCTL=no
 NM_CONTRLLED=no

 ==> ifcfg-eth1 <==
 DEVICE=eth1
 NAME=bond0-slave
 HWADDR=xx:xx:xx:xx:xx:xx
 ONBOOT=yes
 BOOTPROTO=none
 MASTER=bond0
 SLAVE=yes
 USERCTL=no
 NM_CONTRLLED=no

 ==> ifcfg-bond0 <==
 DEVICE=bond0
 TYPE=bond
 BONDING_MASTER=yes
 NAME=bond0
 ONBOOT=yes
 BONDING_OPTS="miimon=100 mode=active-backup"

 ==> ifcfg-bond0.10 <==
 VLAN=yes
 TYPE=vlan
 DEVICE=bond0.10
 PHYSDEV=bond0
 VLAN_ID=10
 BOOTPROTO=none
 NAME=bond0.10
 ONBOOT=yes
 IPADDR=x.x.x.x
 PREFIX=24
 GATEWAY=x.x.x.1
 IPV6INIT=no
 DEFROUTE=yes

 ==> ifcfg-bond0.20 <==
 VLAN=yes
 TYPE=vlan
 DEVICE=bond0.20
 PHYSDEV=bond0
 VLAN_ID=20
 BOOTPROTO=none
 NAME=bond0.20
 ONBOOT=yes
 IPADDR=x.x.x.x
 PREFIX=24
 GATEWAY=x.x.x.1
 IPV6INIT=no
 DEFROUTE=no
