Hey,

Simple question for a new networker..

When I perform the following command it takes forever to execute.

"show running-config"

What could be the possible reasons, I mean it has enough memory and the ios is the same on both machines.. and they are the same model..

Let me know..

Check the size of your running-config file.. if this large the router maybe delay to show..

#dir nvram:

Directory of nvram:/

110 -rw- 14695 startup-config

111 ---- 27 private-config

1 ---- 12 persistent-data

2 -rw- 0 ifIndex-table

129016 bytes total (112194 bytes free)

#

check the cpu utilization

router# sh processes cpu history

Hi Mavrick,

when giving "show run" command it is opening very slow? Can you tell me what is the exact problem & which model?

It is a Cisco AS5850..

It is running slowly, I mean..

"building configuration" and stands still for about 30 seconds..

The thing is that I have deployed many of these and when integrating these new ones, I am experiencing these problems..

model the same,

ram the same,

The only difference is in the bootstrap.. they differ in that respect..

ect..

don't know why..

any idea's???

I think Raul has the right answer. The same thing happens on our ISR routers. Whenever it does happen and I look at the CPU history, the CPU was at 100%. I've had times where I'd issue a command and it took more 1-3 minutes to output it.

I also noticed that certain services on the router use lots of CPU. When I turned nbar off, my CPU averages dropped by 20%. With that off, the CPU still spikes, but not as often and with less dramatic effect.
