Can you also provide the output of "sh redu"?
also, can you reset the stand-by sup?

Console into the redundant supervisor card and reboot it (as Reza has recommended) and post the entire bootup process.

Thanks for your reply.
I will do the same and let you know the bootup process output.

When i tried to take console in secondary sup engine , it is going to Rommon mode ....
11-28-2011 01:37 AM
Have you checked if on the secondary sup there is the correct immage, and in bootvar there is the correct path?
11-28-2011 06:11 AM
As far as My testing concern , I have cross verified i am not getting any output of bootvar details for stand by.
should i boot that with
rommon > boot flash:IOS name
and check whether it is working ...
11-28-2011 06:23 AM
I checked booting with boot flash:IOSname in rommon mode , its booting properly but once it comes up ,.... i have huge spike since it is looping with primary sup.
there is issue with syncronization in between primary and secondary sup.
Can we try to remove all sync. command on primary and bring secondary first up ... once everthing is up ... i can configure the sync. commands later....
please suggest me ...

In Rommon 1, try command dir flash: to show the ios on your flash, aftes see with command set the variable of boot, and if the path is empty edit with boot flash:(file). Also check with confreg if set to proper value 0x2102 if not change this value.

Thanks for your reply.
I understood this proc. but i need to check what are this two spikes related to CPU proc.
12.23% Cat4k Mgmt HiPri
11.35% Cat4k Mgmt LoPri
when i tried to boot from IOS with boot flash:IOSname in rommon mode , i get these spike ....
can you suggest me that , whether i should ignore this spikes....

I haven't understand your question,
the switch detect the sup card now ?
What do you want to know about CPU proc?
