服务器绑定接口configuration

（在http://unix.stackexchange.com上也提出了同样的问题）

我们正在面对服务器configuration的一些问题：有2个服务器，每个服务器都包含2个绑定的NIC。每个服务器连接到2个思科交换机（每个网卡连接到单独的交换机）。交换机上的端口被configuration为具有VLAN 1111.交换机之间也有互连（该VLAN是互连的一部分）。

交换机2上有以下错误（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

在检查configuration时，您可以看到两台交换机都已经学习了1cc1.de7a.04b6的MAC地址

 NLS-PDC-SW2>show mac address-table vlan 1111 Mac Address Table ------------------------------------------- Vlan Mac Address Type Ports ---- ----------- -------- ----- 1111 1cc1.de7a.046a DYNAMIC Gi0/26 1111 1cc1.de7a.04b6 DYNAMIC Gi0/25 Total Mac Addresses for this criterion: 23 NLS-PDC-SW1>show mac address-table vlan 1111 Mac Address Table ------------------------------------------- Vlan Mac Address Type Ports ---- ----------- -------- ----- 1111 1cc1.de7a.04b6 DYNAMIC Gi0/25 Total Mac Addresses for this criterion: 24 NLS-PDC-SW1>

从两个服务器检查modprobe文件我发现，在server2（其中包含1cc1.de7a.04b6）

 alias bond0 bonding options bond0 miimon=100

和server1（其中包含1cc1.de7a.046a）

 alias bond0 bonding options bond0 miimon=100 mode=1

我真的很困惑所需的configuration。你能build议吗？

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configuration：

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

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