When I use switch port mapper on a cisco 6500 IOS. I get all the ports mapped as expected but also a duplicate of each mac/ip address coming from a single fast ethernet port. Only difference is there is no DNS name for the duplicate. Conncted to this port is a Fortigate firewall. Before this fortigate was installed, we never experienced this problem. Anyone any ideas how to get around it ?
Cheers
