華為S9300核心交換機鏈路聚合配置實例

1、華為S9300核心交換機鏈路聚合配置實例配置靜態(tài)LACP模式鏈路聚合示例組網(wǎng)需求如圖1所示，在兩臺S9300設(shè)備上配置靜態(tài)LACP模式鏈路聚合組，提高兩設(shè)備之間的帶寬與可靠性，具體要求如下：· 2條活動鏈路具有負(fù)載分擔(dān)的能力。· 兩設(shè)備間的鏈路具有1條冗余備份鏈路，當(dāng)活動鏈路出現(xiàn)故障鏈路時，備份鏈路替代故障鏈路，保持?jǐn)?shù)據(jù)傳輸?shù)目煽啃?。圖1 配置靜態(tài)LACP模式鏈路聚合組網(wǎng)圖 配置思路采用如下的思路配置靜態(tài)LACP模式鏈路聚合：1. 在S9300設(shè)備上創(chuàng)建Eth-Trunk，配置Eth-Trunk為靜態(tài)LACP模式。2. 將成員接口加入Eth-Trunk。3. 配置系統(tǒng)優(yōu)先級

2、確定主動端。4. 配置活動接口上限閾值。5. 配置接口優(yōu)先級確定活動鏈路。數(shù)據(jù)準(zhǔn)備為完成此配置例，需準(zhǔn)備如下的數(shù)據(jù)：· 兩端S9300設(shè)備鏈路聚合組編號。· S9300-A系統(tǒng)優(yōu)先級。· 活動接口上限閾值。· 活動接口LACP優(yōu)先級。操作步驟1. 創(chuàng)建編號為1的Eth-Trunk，配置它的工作模式為靜態(tài)LACP模式 # 配置S9300-A。<Quidway> system-viewQuidway sysname S9300-AS9300-A interface eth-trunk 1S9300-A-Eth-Trunk1 mode lacp-s
