配置LACP模式链路聚合
组网需求 在两台Router设备上配置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: 两条活动链路具有负载分担的能力。 两设备间的链路具有一条冗余备份链路,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。 配置LACP模式链路聚合组网图 配置思路 采用如下的思路配置LACP模式链路聚合: 1. 在Router设备上创建Eth-Trunk,配置Eth-Trunk为LACP模式,实现链路聚合功能。 2. 将成员接口加入Eth-Trunk。 3. 配置系统优先级,确定主动端,按照主动端设备的接口选择活动接口。 4. 配置活动接口上限阈值,实现保证带宽的情况下提高网络的可靠性。 5. 配置接口优先级,确定活动链路接口,优先级高的接口将被选作活动接口。 操作步骤 创建编号为1的Eth-Trunk,配置它的工作模式为LACP模式 # 配置RouterA。 <Huawei> system-view [Huawei] sysname RouterA [RouterA] interface eth-trunk 1 [RouterA-Eth-Trunk1] mode lacp-static [RouterA-Eth-Trunk1] quit # 配置RouterB。 <Huawei> system-view [Huawei] sysname RouterB [RouterB] interface eth-trunk 1 [RouterB-Eth-Trunk1] mode lacp-static [RouterB-Eth-Trunk1] quit 将成员接口加入Eth-Trunk # 配置RouterA。 [RouterA] interface ethernet 2/0/1 [RouterA-Ethernet2/0/1] eth-trunk 1 [RouterA-Ethernet2/0/1] quit [RouterA] interface ethernet 2/0/2 [RouterA-Ethernet2/0/2] eth-trunk 1 [RouterA-Ethernet2/0/2] quit [RouterA] interface ethernet 2/0/3 [RouterA-Ethernet2/0/3] eth-trunk 1 [RouterA-Ethernet2/0/3] quit # 配置RouterB。 [RouterB] interface ethernet 2/0/1 [RouterB-Ethernet2/0/1] eth-trunk 1 [RouterB-Ethernet2/0/1] quit [RouterB] interface ethernet 2/0/2 [RouterB-Ethernet2/0/2] eth-trunk 1 [RouterB-Ethernet2/0/2] quit [RouterB] interface ethernet 2/0/3 [RouterB-Ethernet2/0/3] eth-trunk 1 [RouterB-Ethernet2/0/3] quit 在RouterA上配置系统优先级为100,使其成为LACP主动端 [RouterA] lacp priority 100 在RouterA上配置活动接口上限阈值为2 [RouterA] interface eth-trunk 1 [RouterA-Eth-Trunk1] max active-linknumber 2 [RouterA-Eth-Trunk1] quit 在RouterA上配置接口优先级确定活动链路 [RouterA] interface ethernet 2/0/1 [RouterA-Ethernet2/0/1] lacp priority 100 [RouterA-Ethernet2/0/1] quit [RouterA] interface ethernet 2/0/2 [RouterA-Ethernet2/0/2] lacp priority 100 [RouterA-Ethernet2/0/2] quit # 查看各Router设备的Eth-Trunk信息,查看链路是否协商成功。 [RouterA] display eth-trunk 1Eth-Trunk1's state information is: Local: LAG ID: 1 WorkingMode: STATIC Preempt Delay: Disabled Hash arithmetic: According to SA-XOR-DA System Priority: 100 System ID: 00e0-fca8-0417 Least Active-linknumber: 1 Max Active-linknumber: 2 Operate status: Up Number Of Up Port In Trunk: 2 ------------------------------------------------------------------------------ ActorPortName Status PortType PortPri PortNo PortKey PortState Weight Ethernet2/0/1 Selected 100M 100 6145 2865 22222100 1 Ethernet2/0/2 Selected 100M 100 6146 2865 22222100 1 Ethernet2/0/3 Unselect 100M 32768 6147 2865 11100000 1 Partner: ------------------------------------------------------------------------------ PartnerPortName SysPri SystemID PortPri PortNo PortKey PortState Ethernet2/0/1 32768 00e0-fca6-7f85 32768 6145 2609 22222100 Ethernet2/0/2 32768 00e0-fca6-7f85 32768 6146 2609 22222100 Ethernet2/0/3 32768 00e0-fca6-7f85 32768 6147 2609 11110000 [RouterB] display eth-trunk 1 Eth-Trunk1's state information is: Local: LAG ID: 1 WorkingMode: STATIC Preempt Delay: Disabled Hash arithmetic: According to SA-XOR-DA System Priority: 32768 System ID: 00e0-fca6-7f85 Least Active-linknumber: 1 Max Active-linknumber: 8 Operate status: Up Number Of Up Port In Trunk: 2 ------------------------------------------------------------------------------ ActorPortName Status PortType PortPri PortNo PortKey PortState Weight Ethernet2/0/1 Selected 100M 32768 6145 2609 22222100 1 Ethernet2/0/2 Selected 100M 32768 6146 2609 22222100 1 Ethernet2/0/3 Unselect 100M 32768 6147 2609 11100000 1 Partner: ------------------------------------------------------------------------------ PartnerPortName SysPri SystemID PortPri PortNo PortKey PortState Ethernet2/0/1 100 00e0-fca8-0417 100 6145 2865 22222100 Ethernet2/0/2 100 00e0-fca8-0417 100 6146 2865 22222100 Ethernet2/0/3 100 00e0-fca8-0417 32768 6147 2865 11110000 通过以上显示信息可以看到,RouterA的系统优先级为100,高于RouterB的系统优先级。Eth-Trunk的成员接口中Ethernet 2/0/1、Ethernet 2/0/2成为活动接口,处于“Selected”状态,接口Ethernet 2/0/3处于“Unselect”状态,同时实现M条链路的负载分担和N条链路的冗余备份功能。 (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
