链路聚合配置
二层链路聚合配置 一、手工负载分担模式配置 (1) LSW1: <Huawei>sys Enter system view,return user view with Ctrl+Z. [Huawei]sysn LSW1 [LSW1]int eth-trunk 1 ? //创建编号为1的eth-trunk端口 [LSW1-Eth-Trunk1]mode ? ? lacp-static ?Static working mode ? manual ? ? ? Manual working mode 注意:eth-trunk工作模式分为手工负载分担模式和lacp模式两种 [LSW1-Eth-Trunk1]mode manual load-balance ? ? ? ? //配置为手工分钟分担模式 [LSW1-Eth-Trunk1]trunkport GigabitEthernet 0/0/1 to 0/0/3 ? //将物理端口G0/0/1,G0/0/2,G0/0/3加入eth-trunk 1 端口 [LSW1-Eth-Trunk1]dis eth-trunk 1 ? //查看eth-trunk端口信息 Eth-Trunk1's state information is: WorkingMode: NORMAL ? ? ? ? Hash arithmetic: According to SIP-XOR-DIP ? ? ? ?? Least Active-linknumber: 1 ?Max Bandwidth-affected-linknumber: 8 ? ? ? ? ? ? ? Operate status: up ? ? ? ? ?Number Of Up Port In Trunk: 3 ? ? ? ? ? ? ? ? ? ?? -------------------------------------------------------------------------------- PortName ? ? ? ? ? ? ? ? ? ? ?Status ? ? ?Weight? GigabitEthernet0/0/1 ? ? ? ? ?Up ? ? ? ? ?1 ? ? ? GigabitEthernet0/0/2 ? ? ? ? ?Up ? ? ? ? ?1 ? ? ? GigabitEthernet0/0/3 ? ? ? ? ?Up ? ? ? ? ?1 ? (2)LSW2也需要同样的配置 <Huawei>sys Enter system view,return user view with Ctrl+Z. [Huawei]sysn LSW2 [LSW2]int eth-trunk 1 [LSW2-Eth-Trunk1]mode manual load-balance? [LSW2-Eth-Trunk1]trunkport GigabitEthernet 0/0/1 to 0/0/3 Info: This operation may take a few seconds. Please wait for a moment... [LSW2-Eth-Trunk1]dis eth-trunk 1 Eth-Trunk1's state information is: WorkingMode: NORMAL ? ? ? ? Hash arithmetic: According to SIP-XOR-DIP ? ? ? ?? Least Active-linknumber: 1 ?Max Bandwidth-affected-linknumber: 8 ? ? ? ? ? ? ? Operate status: up ? ? ? ? ?Number Of Up Port In Trunk: 3 ? ? ? ? ? ? ? ? ? ?? -------------------------------------------------------------------------------- PortName ? ? ? ? ? ? ? ? ? ? ?Status ? ? ?Weight? GigabitEthernet0/0/1 ? ? ? ? ?Up ? ? ? ? ?1 ? ? ? GigabitEthernet0/0/2 ? ? ? ? ?Up ? ? ? ? ?1 ? ? ? GigabitEthernet0/0/3 ? ? ? ? ?Up ? ? ? ? ?1 ? ? ? (3) 回显信息中WorkingMode: NORMAL ,表示eth-trunk1的工作模式为收工负载分担模式,eth-trunk1包含了3个成员端口G0/0/1,G0/0/3, 此时,两台设备之间的三条物理链路聚合在一起,已绑定成为一条逻辑上的链路。 二、静态LACP模式配置 (1)删除LSW1和LSW2上的G0/0/1,G0/0/2和G0/0/3接口下的配置。 LSW1: [LSW1]int g0/0/1 [LSW1-GigabitEthernet0/0/1]undo eth-trunk? [LSW1-GigabitEthernet0/0/1]int g0/0/2 [LSW1-GigabitEthernet0/0/2]undo eth-trunk [LSW1-GigabitEthernet0/0/2]int g0/0/3 [LSW1-GigabitEthernet0/0/3]undo eth-trunk? [LSW1-GigabitEthernet0/0/3]q [LSW1] LSW2: [LSW2]int g0/0/1 [LSW2-GigabitEthernet0/0/1]undo eth-trunk? [LSW2-GigabitEthernet0/0/1]int g0/0/2 [LSW2-GigabitEthernet0/0/2]undo eth-trunk? [LSW2-GigabitEthernet0/0/2]int g0/0/3 [LSW2-GigabitEthernet0/0/3]undo eth-trunk? [LSW2-GigabitEthernet0/0/3]q [LSW2] (2)创建eth-trunk端口,配置为lacp模式,将g0/0/1,g0/0/2,g0/0/3加入eth-trunk端口 LSW1: [LSW1]int Eth-Trunk 1 [LSW1-Eth-Trunk1]mode lacp [LSW1-Eth-Trunk1]trunkport GigabitEthernet 0/0/1 to 0/0/3 [LSW1-Eth-Trunk1]dis eth-trunk 1 ? ?//查看链路协商信息 Local: LAG ID: 1 ? ? ? ? ? ? ? ? ?
