We have 2-3560g (running L3) trunked through a 100Mb MetroEthernet at 2 different location. Recently added a second 5mb MetroE from another ISP for redundancy. Confiugred both 3560g with EIGRP variance 2 and confirmed that the 5Mb MetroE is passing packet.
As soon as I enable the port for the 5mb ME trunk, CPU utilization on both 3560g spiked up to almost 100%. random packet drop start to occur.
During high CPU Utilization:
CPU utilization for five seconds: 88%/19%; one minute: 48%; five minutes: 17%
