博科交換機6510升級FOS
升級原因：現有的EMC6510的FOS版本為v7.2.0.d, 只能使用java1.6訪問webtools，java1.7+不支持，很不爽。
要從 v7.2.0d --> v7.3.1d , 升級包是從QQ群里一位專業博科技術那里要的，很感謝這位兄弟。
升級過程需要30分鍾左右。
1.先准備好一個交換機能連上的ftp，備份現有的配置文件
firmwareshow //查看fos版本
cfgsave //保存配置
configupload //上傳配置文件到ftp服務器上
2.把升級包解壓成一個文件夾放到ftp上如：/v7.3.1d
//升級開始

INFO: Ciphersuite change on switch
HTTPS ciphers will be modified to be compatible with new firmware version
All packages have been downloaded successfully.
Firmware has been downloaded to the secondary partition of the switch.
HA Rebooting ...
到這步，從console連的沒問題，如果從網絡連過來的就斷了，等幾分鍾重連一下就可以了。
3.再次查看版本,顯示如下就升級成功（需要多等10分鍾左右讓交換機兩個分區同步)
SwitchB:admin> firmwareshow
Appl Primary/Secondary Versions
------------------------------------------
FOS v7.3.1d
v7.3.1d
//查看配置都在就OK了
cfgactvshow
DONE
現在就解決了我用java1.7+登陸webtools的問題了，
附: 把配置導到一台新的交換機
switchdisable //先停用交換機
configdownload //從ftp上下載config.txt文件到交換機
cfgsave
cfgenable cfg
switchenable //啟用交換機
