我们有三个 24 端口（千兆）Netgear GS724T 交换机，它们的连接方式如下：
SW-003 > SW-001
> SW-002
SW-002 上连接到 Sw-003 的端口每秒持续闪烁一次，其余端口也在闪烁，因为数据正在按预期传输。
我担心这可能意味着我们面临超过两台交换机之间千兆带宽的风险。如果是这样的话，我推测解决办法是启用生成树 - 我已经尝试过，但我不明白是否需要在所有交换机上启用具有匹配端口的生成树。因此，SW-002 上的端口 1 和 2 具有生成树，SW-003 上的端口 1 和 2 具有启用的生成树。
那是对的吗？
目前，我在两者之间连接了一条额外的跳线，它似乎创建了某种形式的路由循环，导致所有端口每秒闪烁一次，网络停止工作。

不知道闪烁是什么意思，请查看手册或致电 Netgear 了解情况，但这并不意味着您过度使用了链接 - 它们的设计就是整天保持 100% 的速率，所以不用担心。也就是说，如果您想要超过 1Gbps 的带宽，您需要的不是生成树，而是 802.3ad/LACP，这些交换机支持 - 两个或多个链接绑定在一起，基本上作为一个链接。
