Juniper路由器系统维护手册

1. 维护巡检表

每天或者定期对路由器进行检查的检查表

2. 系统基本维护

2.1. 启动时间

通过查看系统的启动时间，可以知道路由器是否重启过。 zte@GDGZ-PB-WAP15-GRE01> show system uptime Current time: 2007-11-27 09:30:18 CST

System booted: 2007-11-06 23:24:25 CST (2w6d 10:05 ago) Protocols started: 2007-11-06 23:24:49 CST (2w6d 10:05 ago) Last configured: 2007-11-22 17:30:49 CST (4d 15:59 ago) by zte 9:30AM up 20 days, 10:06, 2 users, load averages: 0.11, 0.03, 0.01

2.2. 设备温度

通过查看系统感应器的状态，可以知道设备是否运行在一个合理的温度环境下。下面命令输出中“Absent”表示没有安装该硬件。如果状态显示OK则正常。

zte@GDGZ-PB-WAP15-GRE01> show chassis environment Class Item Status Measurement Temp PEM 0 OK PEM 1 OK

Routing Engine 0 OK 35 degrees C / 95 degrees F Routing Engine 1 Absent

CB 0 Intake OK 30 degrees C / 86 degrees F CB 0 Exhaust A OK 32 degrees C / 89 degrees F CB 0 Exhaust B OK 31 degrees C / 87 degrees F CB 1 Intake Absent CB 1 Exhaust A Absent
