Cisco Nexus 7000 upgrade 升級

    運行前，得把cisco nexus 7010 升級到cisco推薦的穩定版本，以后打算一直用，沒事盡量不升版本，cisco搜索nexus 7000 upgrade 有各種文檔，很長的，介紹各種方法，原理，其中有如何升完一個引擎，再升另一個，這樣不中斷生產，但手上這個還沒跑數據，簡單粗暴，install all 一把升完。。。

   其實簡單粗暴或者以后生產過程中升級貌似也沒事，因為有雙引擎，只要操作得當，總會適時一個備引擎升完，切到備上，才升級主，這個過程可以自動完成，也可以你手動，我喜歡一把來，自動搞定

以下是secureCRT抓取，不用擔心很長，多是過程（理解過程，有助于以后生產環境中實現不間斷升版本），簡單粗暴的來總共就下面紅字標出的三個命令（當然命令可拆解，kickstsrt一下，system一下，一把來吧，喜歡自動識別，當然如果我步驟錯誤，或者硬件不支持，或者ios鏡像版本錯了，會有報錯的，比較不錯。）

之前記得把固件傳到sup1 和 sup2的flash中，兩個引擎都要傳啊，文件大用tftp太累，建議開啟feature ssh ，feature sft，用sftp傳，記得sh ver，sh module ，sh boot確認之前狀態

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

之后記得copy running start，保存，然后sh ver，sh module ，sh boot看下有何不同（其實就是sh boot的next boot變了），最后reload 起來后sh ver，sh module ，sh boot（全變了），確認版本正確就行了。

cisco nexus交換機和cisco mds交換機分別用于兩個不同的大方向，但架構貌似一樣，升級過程幾乎一樣

全部過程如下：
