华为S9300核心交换机链路聚合配置实例

1、华为S9300核心交换机链路聚合配置实例配置静态LACP莫式链路聚合示例组网需求如所示，在两台S9300设备上配置静态 LACP模式链路聚合组，提高两设备之间的带宽与可靠性, 具体要求如下：?2条活动链路具有负载分担的能力。? 两设备间的链路具有 1条冗余备份链路，当活动链路出现故障链路时，备份链路替代故 障链路，保持数据传输的可靠性。图1配置静态LACP模式链路聚合组网图Eth-TrunklEth-TrunkiSg300-A GE 131 S930D-B活动钱路备份戳路GE1/0GGE1旧后t-r iih*. nh配置思路采用如下的思路配置静态LACP模式链路聚合：1. 在S9300设备上创

2、建 Eth-Trunk，配置 Eth-Trunk 为静态LACP模式。2. 将成员接口加入 Eth-Trunk。3. 配置系统优先级确定主动端。4. 配置活动接口上限阈值。5. 配置接口优先级确定活动链路。数据准备为完成此配置例，需准备如下的数据：? 两端S9300设备链路聚合组编号。?S9300-A系统优先级。?活动接口上限阈值。?活动接口 LACP优先级。操作步骤1. 创建编号为1的Eth-Trunk，配置它的工作模式为静态LACP模式# 配置 S9300-A。<Quidway> system-viewQuidway sysname S9300-AS9300-A interfa
