Hi all,
Here is the context, we experienced high cpu (99%) on old Cisco2921 due to high NAT/Throughput usage.
We decided to replace the device by ISR4331/K9 with performance license (Enhancing the throughput to 300Mbps). The ISR4331 is a 8-core cpu.
Now I want to compare the gain earned between the old vs the new routers.
So, I did a "show processes cpu sorted" on the ISR, I have 1% cpu usage in the last 5 minutes
But
When I do a "show processes cpu platform sorted " , I have a detailled cpu repartition among the 8 cores but the overall cpu value says 18-20%...
So I don't know which value I have to take ? 1% or 20% ?
Have you got any idea ?
Thanks in advance
