    Duplicate IP and MAC addresses

       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 ?
