原文地址:JUNOS升级步骤

注意:升级时配置和一些其它附属文件会被自动保存,但存放在RE上的本地日志等文件可能会被删除。所以如果需要保存这些日志等文件也应该在升级前使用FTP备份这些文件到服务器上。

1、备份

[email protected]> request system snapshot

[email protected]# save /var/home/xiaocisco/config.junos.txt

[email protected]# run file copy config.junos.txt ftp://username:[email protected]/config.junos.txt

2、将新的JUNOS使用ftp上传至Juniper设备

[email protected]#run file copy ftp://username:[email protected] /var/tmp/junos-jsr-9.5R1.8-domestic.tgz

3、JUNOS安装

[email protected]> request system software add /var/tmp/junos-jsr-9.5R1.8-domestic.tgz

NOTICE: Validating configuration against junos-jsr-9.5R1.8-domestic.tgz.

NOTICE: Use the 'no-validate' option to skip this if desired.

Checking compatibility with configuration

4、重启完成安装

[email protected]# run request system reboot

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