1.1登陆操作CUDB节点中有三类板卡，分别是GEP3板，SCXB(DMX)板和NWI-E板。

我们需要登录这些板子收集相应的日志，可以用SecureCRT，terminal或者其他SSH客户软件登录这些板卡。

有两种方式可以登陆到CUDB：1）C onsole直连Console直连的方式在日常操作维护中不推荐使用。

通过Console直连的操作一般为对于硬件的操作，如更换板卡。

CUDB系统Console连接配置表。

2）通过网管网络连接在对于CUDB的日常操作维护时，推荐通过网管网络连接CUDB。

从OSS登陆SC板卡和DMX板卡使用SSH协议，登陆NWI使用TELNET协议。

CUDB系统网管登陆信息表1.2CUDB 系统检查通常情况下以下检查应该包括在每日健康检查中。

1.2.1CUDB总体系统检查验证整个系统状态。

在CUDB 某块SC板卡上执行这些指令。

执行指令:# cudbSystemStatus命令描述:这条命令自动执行下面的系统状态检查。
