实用文档之华为配置静态LACP模式链路聚合示例

1、实用文档之”华为配置静态LACP模式链路聚合示例“组网需求如图所示，在两台Switch设备上配置静态LACP模式链路聚合组.提髙两设备 之间的带宽与可靠性，具体要求如下：活动链路 备份谨路Eth-Trunk 1Switch* E(h0/Q/1 zEth 0/0/2 (Eth 0/0/3 IEth-Trunk 10 巳hSwitchBEth 0/0/32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，当活动链路岀现故障链路时，备份链 路替代故障链路，保持数据传输的可靠性。图配置静态LACP模式链路聚合组网图配置思路采用如下的思路配置静态LACP模式链路聚合：在Switch设备上

2、创建Eth-Trunk,配置Eth-Trunk为静态LACP模式。将成员接口加入Eth-Trunko配置系统优先级确左主动端。配置活动接口上限阈值。配置接口优先级确左活动链路。数据准备为完成此配置例，需准备如下的数据：两端Switch设备链路聚合组编号。SwitchA系统优先级。活动接口上限阈值.活动接口 LACP优先级。操作步骤创建编号为1的Eth-Trunk,配宜它的工作模式为静态LACP模式# 配置 SwitchAu system-viewQuidwayJ sysname SwitchAESwitchA. interface eth-trunk 1ESwitchA-Eth-Trunk1
