I have a flat network, 3 switches, a 4006 uplinked to both a 6509 and another 4006. My problem is that the cpu utilization is over 50% on the 4006. I have only one vlan, and everyone is in it, I know multiple vlans would help, but management is agenst it. I also have EXTREMELY high broadcast traffic from just about all workstations, from what I have read, this could cause the high cpu... but what I don't know is what woulod cause all ports to have a high broadcast traffic .. most are at 97%. Can anyone PLEASE help me understand this???? I am brand new to this company, and the consultant who set the network up, and who still comes around says it was never this high before, but I have my doubts.
