Hello,
Try to run the following script from another dom0 in the same LAN. This script could be considered as an "hack" to update the CAM table of the switch : 

#!/bin/bash
if [ -z "$1" ]; then
  echo "Error: give the DomU IP to ping as parameter."
  exit 1
fi
HOSTNAME=$1
while /bin/true;do
        /sbin/ip neigh flush all &>/dev/null
        ping -c1 -w1 $HOSTNAME 
        sleep 0.2
done

Jordan
