升级指南

引言
对VMWare虚拟机下的Juniper模拟器进行软件版本升级，从版本8.1R1.5升级到版本8.3R2.8。
升级准备
VMware 5.5模拟器软件：运行版本8.1R1.5的JUNOS；
Named Pipe TCP Proxy软件：提供终端控制台和模拟器之间的登陆方式；
终端控制台：登陆模拟器，通用的终端控制台即可；
WFTPD：提供ftp server功能；
待升级版本：jinstall-8.3R2.8-export-signed.tgz。
首先打开VMWare的模拟器，将其中的一块网卡和虚拟网卡关联起来，这样模拟器就可以通过该虚拟网卡和windows操作系统通信了，如下图所示，我将模拟器的网卡和虚拟网卡VMnet2关联起来：
同时配置VMnat2的ip地址如下图所示：
然后启动WFTPD软件，并设置好相关的用户帐号，并将待升级文件拷贝到用户帐号指定的目录下，如下图所示：
这样，升级前准备工作就完成了。
软件升级
启动Named Pipe TCP Proxy和虚拟机，并通过终端登陆上Juniper的模拟器，详细内容可以参考文档《Juniper模拟器使用指南》，此处略过。
Juniper模拟器启动完毕后，通过下面的命令我们可以看到当前的JUNOS版本还是8.1R1.5。

这时退出模拟器的cli模式，将当前目录切换到/var/tmp下，一般都习惯于将升级文件统一下载到这个目录下，这只是一个习惯，大家可以根据自己的实际情况选择存放JUNOS升级文件的目录，然后通过ftp方式访问VMnet2网卡，并下载jinstall-8.3R2.8-export-signed.tgz文件到虚拟机的操作系统上，如下所示：
root@R1> exit /*

此时进入JUNOS的cli模式，通过命令添加升级文件包，该添加过程会对整个升级文件进行一系列的检查，比如CRC校验、版本一致性对比、配置文件一致性对比等等，如下所示：
root@R1% cli /*
进入

模式
*/
root@R1> request system software add /var/tmp/jinstall-8.3R2.8-export-signed.tgz force
/*

至此整个升级文件的添加过程就进行完毕了，此时需要重启JUNOS，重启之后就完成了整个软件版本的升级过程，通过如下命令重启JUNOS：
root@R1> request system reboot /*

*/
Reboot the system ? [yes,no] (no) yes

可以看到，JUNOS已经成功升级到8.3R2.8版本，先写到这吧，因为是自己第一次升级JUNOS的软件版本，写个文档记录一下升级的关键步骤，接下来会琢磨一下新版本的特性是否有自己用的上的地方。
