网络工程 - 为什么我的 Cisco 4507 核心交换机无法识别我的 SFP+？ - 吾爱随笔录

我有一条可疑的 SFP+ 电缆（我认为它是仿制品），我试图用它来连接 Cisco 2960S 堆栈和 4507 核心机箱。我在下面包含了我认为相关的信息，但请随时提出更多要求，我会提供。双方都没有抱怨它是一个不兼容的 SFP 模块或任何类似的东西。如果我将电缆连接在两个 2960S 之间，它就可以正常工作。SFP 电缆似乎不再在亚马逊上列出，但这里有一个类似的版本，让您了解我正在使用的产品：Diablo 15m 直连 SFP+

我的 4507 显示“inactive”状态，而 2960S 显示“notconnect”让我相信问题可能出在 4507 上。我尝试了这个service unsupported-transceiver技巧，但它没有影响“inactive”状态。

这是4507端：
