运行前，得把cisco nexus 7010 升级到cisco推荐的稳定版本，以后打算一直用，没事尽量不升版本，cisco搜索nexus 7000 upgrade 有各种文档，很长的，介绍各种方法，原理，其中有如何升完一个引擎，再升另一个，这样不中断生产，但手上这个还没跑数据，简单粗暴，install all 一把升完。。。
其实简单粗暴或者以后生产过程中升级貌似也没事，因为有双引擎，只要操作得当，总会适时一个备引擎升完，切到备上，才升级主，这个过程可以自动完成，也可以你手动，我喜欢一把来，自动搞定
以下是secureCRT抓取，不用担心很长，多是过程（理解过程，有助于以后生产环境中实现不间断升版本），简单粗暴的来总共就下面红字标出的三个命令（当然命令可拆解，kickstsrt一下，system一下，一把来吧，喜欢自动识别，当然如果我步骤错误，或者硬件不支持，或者ios镜像版本错了，会有报错的，比较不错。）
之前记得把固件传到sup1 和 sup2的flash中，两个引擎都要传啊，文件大用tftp太累，建议开启feature ssh ，feature sft，用sftp传，记得sh ver，sh module ，sh boot确认之前状态 boot kickstart bootflash:n7000-s2-kickstart.6.2.16.bin sup-1 sup-2 boot system bootflash:n7000-s2-dk9.6.2.16.bin sup-1 sup-2 install all kickstart bootflash:n7000-s2-kickstart.6.2.16.bin system bootflash:n7000-s2-dk9.6.2.16.bin install all kickstart bootflash:n7000-s2-kickstart.6.2.16.bin system bootflash:n7000-s2-dk9.6.2.16.bin
之后记得copy running start，保存，然后sh ver，sh module ，sh boot看下有何不同（其实就是sh boot的next boot变了），最后reload 起来后sh ver，sh module ，sh boot（全变了），确认版本正确就行了。
cisco nexus交换机和cisco mds交换机分别用于两个不同的大方向，但架构貌似一样，升级过程几乎一样
全部过程如下： switch(config)# sh version ###显示现在运行的版本为6.2.2a
