我刚刚在服务器上现有的 4gb 端口上添加了额外的 1gb 端口。所有 4 个端口都放在网卡上PCIE 1GB E1G44HTBLK 904223 INTEL
，而额外的端口连接到主板 (S5520SC) 集成以太网端口。
从 dmidecode 我可以看到主板端口已启用。但我无法使用 ifconfig 看到连接的端口，也没有/var/log/messages

答案1
如果此文件存在，则删除 /etc/udev/rules.d/70-persistent-net.rules。现在创建您自己的 /etc/sysconfig/network-scripts/ifcfg-eth6 文件。还要确保所有网络地址都在相应的配置文件中及时更新。
否则，您可以在此文件 /etc/udev/rules.d/70-persistent-net.rules 中附加新的网络设备详细信息
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="xx:xx:xx:xx:xx:xx", ATTR{type}=="1", KERNEL=="eth*", NAME="eth5"
答案2
您确定没有配置绑定吗？从上面看，您似乎启用了绑定。如果为接口启用了绑定，则不会显示任何 IP。
