BOOT = bootflash:cat4500-entservicesk9-mz.122-31.SGA7.
Configuration register = 0x2102
Peer (slot: 2) information is not available because it is in 'DISABLED' state
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 ...
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.
