华为QUIDWAY 系列华为交换机操作手册 MAC地址转发表管理操作
z 如果 MAC 地址转发表中尚未包含 MAC-SOURCE，交换机则将这个新 MAC 地址（以及该 MAC 地址对应的转发端口）作为一个新的表项加入到 MAC 地 址转发表中。

Quidway S3900 系列以太网交换机 操作手册-Release 1510 MAC 地址转发表管理
1.1 MAC 地址转发表管理简介
1.1.1 MAC 地址学习功能简介
为了快速转发报文，以太网交换机需要维护 MAC 地址转发表。MAC 地址转发表是 一张基于端口的二层转发表，是以太网交换机实现二层报文快速转发的基础。MAC 地址转发表的表项包括：
z 目的 MAC 地址 z 端口所属的 VLAN ID z 转发端口号 以太网交换机通过查找 MAC 地址转发表得到二层报文的转发端口号，从而实现二 层报文的快速转发。 MAC 地址转发表中的动态表项（非手工配置）是由以太网交换机学习得来的。以太 网交换机学习 MAC 地址的过程如下： 如果从某端口（假设为端口 1）收到一个数据帧，以太网交换机就会分析该数据帧 的源 MAC 地址（假设为 MAC-SOURCE）并认为目的 MAC 地址为 MAC-SOURCE 的报文可以由端口 1 转发。
z 如果用户设置的老化时间太短，以太网交换机可能会删除有效的 MAC 地址表 项，降低转发效率。
