Cisco ios -将15.2装入催化剂2960

Question

是否可以将cisco ios 15.x加载到旧的2960或3560中？我试图这样做(学习的目的)，这是一个错误。我看到的错误显然是在解压缩图像时做的，或者至少这就是我所看到的。是因为引导加载程序(12.2版)无法处理新映像吗？任何指针，如果它可以工作，将是感激的。

下面是2960的输出

Answer 1

在2960系列中有不同的型号。查看您的"sh版本“输出，您有WS-C2960-24TT-L。根据思科网站的说法，你能得到的最新IOS是15.0.2-SE 11。

您正在尝试安装一个c2960l通用9-mz.152-5c.E.bin映像为2960l开关。这不管用。

其他开关系列(例如3750* )也是如此。
