• 由于静态聚合组中端口选中状态不受对端端口是否在聚合组中及是否处于选中状态的影响。这 样有可能导致两端设备所确定的 Selected 状态端口不一致，当两端都支持配置静态和动态聚 合组的情况下，建议用户优选动态聚合组。
• 配置或使能了下列功能的端口将不能加入二层聚合组：RRPP、MAC 地址认证、端口安全模 式、IP Source Guard 功能、802.1X 功能以及 Portal 免认证规则源接口。
• 配置聚合组的成员端口过程中，建议配置顺序：在端口视图下使用 display this 命令查看端口 上是否存在第二类配置（包括端口隔离配置、QinQ 配置、VLAN 配置、MAC 地址学习配置）， 如果有这类配置，请使用对应的 undo 命令删除这些配置，使端口保持在缺省第二类配置状态， 然后再把端口加入到新创建的聚合组内。
• 只有工作在二层模式下的端口才能加入二层链路聚合组。
1.2.5 配置步骤
1. Switch A的配置 # 进入系统视图，并配置全局按照报文的源 MAC 地址和目的 MAC 地址进行聚合负载分担。
<SwitchA> system-view [SwitchA] link-aggregation load-sharing mode source-mac destination-mac
