If the switch has a large MAC address table, you can see high CPU usage on a switch, due to the SNMP protocol requiring them to be returned in order.

See this: http://www.cisco.com/en/US/tech/tk648/tk362/technologies_tech_note09186a00800948e6.shtml

Not sure if this is the problem, but it is the first thing that comes to mind.

Hello All,

i'm new on here.

i look on my HP Switch CPU usage = 66%
when i stop the Observium, the CPU usage on Switch Down to 7%
when i start the Observium again, the CPU usage Up to 66% again

could someone tell me what might be causing so much CPU usage on the switch?

Thanks,
