Now, I know a smoking-gun is how we store our blocked IPs and how many we have. - Data Compare - Added "Select All" button to "Find" dialog. Typically, memory problems boil down to either: 1) There is not enough memory, or 2)There is adequate memory, but it is not managed well (i. This can happen because of high CPU utilization (i. 2 IOS Image Management. It can also plot CPU and RAM memory utilization based on a predefined polling interval using a chart that refreshes continuously frequently. Troubleshooting Steps: We have checked RSI(request Support Information) and show log command outputs from router. The sites for registered users are noted beside the link. Policy Dell Force 10 S50 and C300. These two network monitoring solutions come with different pricing plans. I'm trying to figure out what's causing this (and how to get this high load back down).

To determine if these interceptors are causing high CPU usage, search the ByteCodeTransformer*. A) Support Duties: 1. Otherwise, you can purchase a firewall. Cisco IOS treats the Debug process as high-priority and it can consume significant amount of router resources thus extensive debugging in production networks is not encouraged. CPU utilization is defined as the percentage of time the CPU spends on processing, instead of sitting idle. l - Unallocated (unassigned) number. During base lining or troubleshooting activity you may need to determine out the CPU Utilization of your Cisco router or Switch.
