升级cisco 3750G的IOS由刀豆文库小编整理，希望给你工作、学习、生活带来方便，猜你可能喜欢“升级ciscoios”。
升级cisco 3750G的IOS支持高级路由与h功能
为了能让cisco交换的远程连接对于账号密码的安全性有所提高，可以用h方式连接终端，但是很多出厂的交换机默认的ios是不支持h这个功能的，为了能让cisco交换机支持h，必须升级带“K9”的IOS.下面是出厂cisco 3750G-24TS默认ios的截图
3750交换机支持SSH需要12.1（11）EA1以上版本软件。
emi是增强型多层镜像，也就是对路由协议的支持更全；而smi是标准多层镜像。特性集共有三种：IP BASE、IP Services和Advanced IP Services。
IP BASE：支持第2层转发和基本的第3层路由，包括EIGRP stub模式。IP Services：包括IP BASE特性集，支持高级第3层路由，如OSPF和组播路由。
Advanced IP Services：包括IP Services，支持IPv6功能。解决方案步骤：
1.从cisco官网下载ios 2.升级ios
3.配置交换机支持h
