NETGEAR 8800 Chassis Switch CLI Manual multicast unicast port_list all Specifies enabling egress flooding only for multicast packets. Specifies enabling egress flooding only for unknown unicast packets. Specifies one or more ports or slots and ports. Specifies all ports on the switch. Default Enabled for all packet types. Usage Guidelines Use this command to re-enable egress flooding that you previously disabled using the disable flooding ports command. The following guidelines apply to enabling and disabling egress flooding: • Disabling multicasting egress flooding does not affect those packets within an IGMP membership group at all; those packets are still forwarded out. If IGMP snooping is disabled, multicast packets are not flooded. • Egress flooding can be disabled on ports that are in a load-sharing group. If that is the situation, the ports in the group take on the egress flooding state of the master port; each member port of the load-sharing group has the same state as the master port. • FDB learning is independent of egress flooding. FDB learning and egress flooding can be enabled or disabled independently. • Disabling unicast or all egress flooding to a port also stops packets with unknown MAC addresses to be flooded to that port. • Disabling broadcast or all egress flooding to a port also stops broadcast packets to be flooded to that port. You can disable egress flooding for unicast, multicast, or broadcast MAC addresses, as well as for all packets on the ports of the NETGEAR 8800 series switches. The default behavior for the NETGEAR 8800 series switches is enabled egress flooding for all packet types. Example The following command enables egress flooding on slot 1, ports 1 and 2 on a NETGEAR 8800 switch: enable flooding all_cast port 1:1-1:2 enable learning iparp sender-mac enable learning iparp {request | reply | both-request-and-reply} {vr } sender-mac Description Enables MAC address learning from the payload of IP ARP packets.
