升级或重新安装之前Junos OS演化版
总结 升级或重新安装 Junos OS Evolved 之前,必须保存一些系统信息,确保有足够的磁盘空间,并备份当前软件和配置。
您需要收集和保存有关系统当前状态的信息,以便您可以在升级之前和之后比较状态,以确保系统配置正确且正常运行。升级之前,您还需要快照系统软件和配置,以便在必要时恢复系统。
- 要检查是否有足够的磁盘空间可用于安装,请使用操作
show system storage
模式命令。各种目录存储已安装的软件版本和数据文件,例如日志和核心文件。如果 (/soft、 /var 或 /data) 目录的容量达到 90% 及以上,则设备没有足够存储空间来安装软件包。如果这些目录没有足够空间,软件安装可能失败。
建议您在设备上存储的软件版本不能超过 5 个。请使用操作
request system software delete
模式命令删除较旧或未使用的软件版本。要删除软件的当前版本和回滚版本,请使用 操作request system software delete archived
模式命令。如果存储
request system storage cleanup
区域( /var 目录)已完全可用,请使用操作模式命令。建议在将新映像复制到 /var/tmp 目录中之前发出此命令,因为如果 /var 分区空间不足,此命令可能会移除该映像。有关详细信息,请参阅 确保有足够的磁盘空间进行升级。
示例输出显示有关设备文件系统中用于FPC和路由引擎的可用磁盘空间量的统计数据。

- 要保存协议信息,请使用
show
操作模式命令save filename
以及为设备配置的协议选项。要发现哪些类别显示命令show ?
可用,请CLI操作模式提示符键入 ,而系统则使用可用类别列表进行响应。然后选择类别,例如bgp
。输入show bgp ?
将显示可用于该类别的 show 命令列表。user@host> show bgp ?
