服务器绑定接口配置

2024-5-29 • tag-icon

（同样的问题在http://unix.stackexchange.com）

我们在服务器配置方面遇到了一些问题：有 2 台服务器，每台服务器包含 2 个绑定的 NIC。每台服务器连接到 2 个 Cisco 交换机（每个 NIC 连接到单独的交换机）。交换机上的端口配置为具有 VLAN 1111。交换机之间也有互连（此 VLAN 是互连的一部分）。

switch2上出现以下错误（Gi0/25是服务器连接的地方，Gi0/30是互连）

*Jun  1 16:18:23.182: %SW_MATM-4-MACFLAP_NOTIF: Host 1cc1.de7a.04b6 in vlan 1111 is flapping between port Gi0/25 and port Gi0/30 
*Jun  1 16:18:45.093: %SW_MATM-4-MACFLAP_NOTIF: Host 1cc1.de7a.04b6 in vlan 1111 is flapping between port Gi0/30 and port Gi0/25 
*Jun  1 16:18:56.031: %SW_MATM-4-MACFLAP_NOTIF: Host 1cc1.de7a.04b6 in vlan 1111 is flapping between port Gi0/25 and port Gi0/30 
*Jun  1 16:19:15.141: %SW_MATM-4-MACFLAP_NOTIF: Host 1cc1.de7a.04b6 in vlan 1111 is flapping between port Gi0/25 and port Gi0/30 
*Jun  1 16:19:23.479: %SW_MATM-4-MACFLAP_NOTIF: Host 1cc1.de7a.04b6 in vlan 1111 is flapping between port Gi0/30 and port Gi0/25 
*Jun  1 16:19:45.616: %SW_MATM-4-MACFLAP_NOTIF: Host 1cc1.de7a.04b6 in vlan 1111 is flapping between port Gi0/30 and port Gi0/25

检查配置时，你可以看到两个交换机都已获悉 1cc1.de7a.04b6 MAC 地址

NLS-PDC-SW2>show mac address-table vlan 1111 
          Mac Address Table

检查两台服务器上的 modprobe 文件，我发现 server2 上（包含 1cc1.de7a.04b6）

alias bond0 bonding
options bond0 miimon=100

以及 server1 （包含 1cc1.de7a.046a）

alias bond0 bonding
options bond0 miimon=100 mode=1

我对所需的配置感到很困惑。您能给出建议吗？

答案1

循环（模式 0）绑定中的端口需要位于 EtherChannel 中。

阅读绑定文档，第 5 章交换机配置：

https://www.kernel.org/doc/Documentation/networking/bonding.txt

此外，modprobe 不是配置绑定选项的正确位置，您应该BONDING_OPTS="miimon=100 mode=X"使用/etc/sysconfig/network-scripts/ifcfg-bondX
