Hi all,
I've got a problem that I am not able to figure out.
I've got 2 nexus 5020 running
Software
system: version 5.0(2)N2(1)
system image file is: bootflash:/n5000-uk9.5.0.2.N2.1.bin
Hardware
cisco Nexus5020 Chassis ("40x10GE/Supervisor")
I use Nagios for management and so far, everything is working fine. Since a couple of days, I was thinking to install dcnm 6.1.1a on a red hat linux to test the app and see what can I do with the nexus. The problem is that every time that I try to work with the DCNM app, the CPU goes up a lot.
The show process cpu history is the following:

Could SNMP be the cause of this high CPU? How could I confirm it? Maybe it is a bug but I could not find anything.
Any ideas or comments are welcomed!
THanks in advance,

Just to close this thread, we saw that the average cpu utilization is 10%. The CPU spikes might be due to the polling time or some cosmetic output. There is no output error, no discards, no traffic loss.
thanks in advance,
Fernando
