Hi, Since the students came back we have has high CPU utilization come and go on our core routers. After much time looking at traffic patterns we have seen this traffic coming only from our Aruba IAP VC buildings. We have other building have Juniper wireless with a central controller. The reason for the high CPU appears to be two wireless devices getting the same IP address. Once this happens gratuitous arps flood the uplinks and crush our CPUs
The leases in our DHCP server mark them as bad. We are using Microsoft DHCP. Has anyone experienced anything like this? Thanks, Mark ********** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/.
