一次不成功的思科2960S交换机的IOS升级

公司一台设备, WS-C2960S-24TS-L,是思科24口1000M的二层交换杨,使用的IOS版本为12.2(55) universalk9-M的IOS软件,最近公司安装了一些数字摄像头,把监控主机和一台球型监控接到了这台机器上,接口的收发速率远大于普通办公用的速率,下面是我复制的两个接口的速率。

Upgrade Cisco 3560X IOS Take 30+ Minutes

https://blog.csdn.net/netsec51sec/article/details/98956759


When working on IOS update for one standalone Cisco 3560x to meet our environment requirement, I was so surprising the total time for Cisco 3560x taking new IOS image, which was more than 30+ minutes. I was thinking to reset it during the process because it is way longer than other Cisco routers, switches and firewalls I updated before. Usually total IOS update takes less than 5 minutes from the beginning process of uploading ios to new ios fully loaded.
