LACP链路聚合模式对接（或替换）指导
LACP链路聚合介绍
由于不同厂商的链路聚合模式和配置各不相同，那么如何在不同厂商设备之间做链路聚合呢？
因为LACP属于公有协议，LACPDU报文一致，所以华为设备能够对接（或替换）支持LACP模式的厂商设备。这里分别给出华为设备与CISCO、H3C、Juniper厂商设备之间通过LACP模式链路聚合对接的情况，如表3-1所示。
表3-1 LACP模式链路聚合对接情况
厂商 |
对应的LACP链路聚合模式及命令 |
|---|---|
华为 |
静态LACP模式 mode lacp-static |
CISCO |
静态LACP模式 channel-group number mode active channel-group number mode passive |
H3C |
动态LACP模式 link-aggregation mode dynamic |
Juniper |
LACP模式 [edit interfaces interface-name aggregated-ether-options]
lacp {
active;
}
[edit interfaces interface-name aggregated-ether-options]
lacp {
passive;
}
|
典型组网案例
在对接（或替换）时，需要注意设备的链路聚合模式是手动还是LACP，保证两端的模式一致（即手动和手动对接，LACP模式与LACP模式对接）且两端物理接口的数量要保持一致。下面分别给出华为设备通过LACP模式对接（或替换）CISCO、H3C、Juniper厂商设备的示例。
注：以下涉及接口名称的内容只是用作标注，具体接口的名称以实际的设备为准。
案例一：华为设备对接（或替换）CISCO设备
- 组网图图3-1 华为设备对接（或替换）CISCO设备
- 操作步骤
创建链路聚合组，配置LACP模式并将接口加入Eth-Trunk。
