Hi there, i have a high cpu problem in cisco 7609. I have excluded the ip.21,ip.22 and at to stop the nms from polling the routing table and the arp table, but the high cpu load still goes on. I have sniffed a huge number of get-request from some NMS and seems that the checksum is incorrect printing a "maybe caused by UDP checksum offload"message. The polling takes place every 4 minutes and has to do with the router's interfaces,protocols and mpls etc, but the load happens at unexpected times!.Does anyone know what might be going on?Is there any other object's i have to exclude in order to stop the cpu load?

Do you see any CPUHOG messages in the logs or any messages that indicates which OID is polled?


What do you see in show logging history?

Hi there, no logging regarding snmp exists! I suddenly have a snmp-engine to 100% and then it suddenly stops no log no nothing!
