Re: High CPU Temp in Routing Engine (master)

Seems like the RE CPU is running high.  Could you paste the output of 'show system process extensive'?

 

Any errors being reported in 'show log messages'?

Re: High CPU Temp in Routing Engine (master)

Also, do a monitor interfaces and see how much traffic is flowing in and out.

 

If it's miniscule and the CPU utilization is still high you might have some other problems.

Re: High CPU Temp in Routing Engine (master)

Yes we've change the mastership between Routing Engine. After conversion, it came back to normal state.

 

Now the Routing Engine 0 is working fine with normal temperature.

 

Thanks alot for your time and efforts.  :-)
