The router (sup720) is configured with logging severity level 7. Shouldn't the router generate log messages when the CPU is loaded to 99%? In our case it doesn't.
We know that the posible cause of this is high amount of Input queue drops on one of gig interfaces. I think it's because of a broadcast storm, and we need to identify the source of it
What do I need is that the router should generate a trap when the CPU load is above 50%(for example). In this way someone at management can start a capture of packets comming to the router via one of its interfaces. How can I achieve that?
CPU Thresholding Notification will do this via an SNMP trap.
You will have to check feature navigator however to see if it's available for the Sup720 yet.
