3。4。5获得系统设备告警(SHOW CHASSIS ALARM)

3。4。6了解系统FPC运行情况(SHOW CHASSIS FPC)
SLOTSTATE:可能的状态有:EMPTY/ONLINE/OFFLINE/PRESENT/UNRESPONSIVE
当在设备上新插入一块FPC时;系统会显示PRESENT状态表明该硬件已备路由器检测到;可以通过命令(见下)或按压FPC按钮的方式使其ONLINE。
Request chassis fpc slot x online'offline';若反复使用该命令后发现其状态为UNRESPONSIVE;通过更换此FPC的槽位仍不奏效;则可初步认为该板已损坏。请联系集成商或厂商作确认和返修。

3。4。7路由引擎状态检测(SHOW CHASSIS ROUTING…ENGINE)
该命令提供系统管理员路由模块的工作状态/利用率:默认状态是SLOT0为主用;SLOT1为备用;可以通过以下命令将备用模块切换到主用状态:
REQUEST SYSTEM ROUTING…ENGINE MASTER
NOTE:应用该命令可直接导致转发数据中断一段时间(路由器重新确认主备关系的时间+路由协议重新收敛时间)
可以通过连接路由模块的仿真终端获得更多的诊断信息。在多数RE的返修案例中;很多是由于路由模块无法正常启动所至(内部FLASH或HARDDISK)损坏。
如何改变路由模块的启动顺序:可以通过仿真终端在路由模块启动时刻改变其启动顺序(默认为:外部FLASH……》内部FLASH……》内部HARDDISK)。当启动至BOOT:时可键入0:wd(1;a)kernel这样路由模块可从内部HARDDISK启动。
