A high cpu utilization

[donglee]

HI all



we are facing core switch high CPU Utilization problem pls help me. This is the log on my core cisco 4506E switch:


Dec 25 16:38:47: %SYS-1-CPURISINGTHRESHOLD: Threshold: Total CPU Utilization(Total/Intr): 83%/1%, Top 3 processes(Pid/Util): 52/65%, 51/5%, 104/5%

Dec 25 16:40:12: %SYS-1-CPUFALLINGTHRESHOLD: Threshold: Total CPU Utilization(Total/Intr) 20%/0%.

My huawei S3700-28TP-EI-DC is a new switch that uplink to this cisco WS-C4506-E core switch. If cisco and huawei cannot interconnect with each other? Any suggestion?

High CPU and host flapping? Probably a switching loop. You were asking for help with LAG earlier, so if the rest of the switch ports are accounted for, I'd verify that is set up correctly.
