Hey folks:

We run spans/monitors ports all the time and we have not found such a limitation. One would want to have the monitor port in the same vlan as the monitor source to catch ALL traffic. It seems that you will catch more traffic by moving the port in the same vlan as the span, just seems to be the better way to sniff. I would check to make sure that you are not getting errors on your port as this might be one cause of your traffic limitation.
