无法将调用命令显示为从主RE备份RE

Question

我有一个MX960框，它面临如下问题。Mater (RE1)不能在备份RE (RE0)上显示任何命令调用，例如:在所有路由引擎上显示版本调用。

{master}

nms@MX960> request routing-engine login other-routing-engine   

connect to address 128.0.0.4: Operation timed out

Trying 10.0.0.4...

re0: Operation timed out

connect to address 128.0.0.4: Operation timed out

Trying 10.0.0.4...

re0: Operation timed out

 

####show database-replication summary

    Database                   Available

    Message Queue              Not Ready

 

####show task replication

    BGP                     NotStarted           

    MPLS                    NotStarted           

    RSVP                    NotStarted           

    LDP                     NotStarted  

我检查了备份RE (RE0)上的日志，并得到了ESW端口13 (接口连接、SCB0和RE0)多次切换的接口。但是，它又启动了，但是在RE1中，我仍然不能显示任何命令调用- (RE0)。

从主机RE，显示底盘路由引擎，我看到所有的REs (RE0是备份，RE1是主)。但是从备份RE，显示底盘路由引擎，主RE的状态是存在的.

在我重新启动RE0之后，一切都好。有谁面临同样的问题吗？请给我一些你的观点。谢谢。

Answer 1

我检查了RE0 (备份RE)的日志chassisd，在端口13切换之前没有发生特殊事件。端口13瓣多次。但在下面的时间里，我观察到奇怪的日志，我不断地推。

日志"fru_is_present:超出范围插槽1用于“不断推送，直到我们重新启动RE0。正常情况下，在RE0联机之后，我们只观察到以下日志：

看上去像是某种软件缺陷。我会为你的设备向支援小组打开一个箱子。
