Hi.We are seeing a high CPU load on the router (Cisco 2921). All other problems are a consequence of this.At the same time, there is only one high-load process in the show proc cpu command output:CPU utilization for five seconds: 99%/47%; one minute:...
According to Cisco documentation, the performance of 2921 is up to 479 kpps or 3.5 Gbps on large packets. A typical packet mix should be around 1 Gbps.An indirect confirmation is that the encryption performance is up to 207 Mbps.40+% in IP Input conf...
