博科交换机6510升级FOS
升级原因：现有的EMC6510的FOS版本为v7.2.0.d, 只能使用java1.6访问webtools，java1.7+不支持，很不爽。
要从 v7.2.0d --> v7.3.1d , 升级包是从QQ群里一位专业博科技术那里要的，很感谢这位兄弟。
升级过程需要30分钟左右。
1.先准备好一个交换机能连上的ftp，备份现有的配置文件
firmwareshow //查看fos版本
cfgsave //保存配置
configupload //上传配置文件到ftp服务器上
2.把升级包解压成一个文件夹放到ftp上如：/v7.3.1d
//升级开始

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 ...
到这步，从console连的没问题，如果从网络连过来的就断了，等几分钟重连一下就可以了。
3.再次查看版本,显示如下就升级成功（需要多等10分钟左右让交换机两个分区同步)
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
现在就解决了我用java1.7+登陆webtools的问题了，
附: 把配置导到一台新的交换机
switchdisable //先停用交换机
configdownload //从ftp上下载config.txt文件到交换机
cfgsave
cfgenable cfg
switchenable //启用交换机
