Linux 綁定與 VLAN 問題

您認為以下配置有意義嗎？BONDTING_OPTVLAN介面是否支持？我想確保我的介面在上游設備關閉時故障轉移。

ifcfg-債券0

$ 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

您需要配置設備，然後是綁定，最後是 VLAN 配置文件。您還必須注意哪些屬性在哪裡起作用，例如bonding_opts，它只能在綁定中，而不是VLAN配置文件，因為VLAN文件將無法直接訪問乙太網連接。

我還發現了這個 RHEL 6 文件，它對此進行了更多解釋。對於 RHEL 7 / CentOS 7，它仍然非常可靠。

• 通過綁定配置 VLAN

添加：

綁定負責管理綁定使用的物理連接。VLAN 無法看到物理連接，如下面的驅動程序輸出所示；他們只看到對他們負責的設備，在這種情況下是bond0。

這裡還解釋了另一種觀點： bonded-and-primary-virtual-ip-addresses-and-vlan-tagged Answer

筆記：

• 我知道這很有效，因為我讓它在 RHEL 7 系統上工作。
• 如果您需要更多 VLAN，只需cp ifcfg-bond0.20 ifcfg-bond0.30更新必填欄位。

圖表：

eth0         vlan1
   \       / 
     bond0 -vlan2
   /       \
eth1         vlan3

例子：

$$ Working config $$

==> ifcfg-eth0 <==
