Conversely, if you want all multicast traffic to be flooded on all ports, but some specific traffic to be restricted, use mac-flood-list with the min-speed option, but without restrict-flooding configured. This configuration restricts flooding only for traffic with destination multicast MAC addresses within the multicast MAC address range you specify. In Figure 24-9, flooding of unknown multicast traffic is restricted to 1G ports on VLAN100 using the command restrict-flooding. However, the command mac-flood-list allows traffic with MAC addresses 01:01:e8:00:00:00 to 01:01:e8:ff:ff:ff to be flooded on all ports regardless of link speed. Figure 24-9.

It responds by sending a unidirectional report that triggers an echoed response after a specified time interval. FEFD can be enabled globally or locally on an interface basis. Disabling the global FEFD configuration does not disable the interface configuration. Layer 2 | 535
