NETGEAR 8800 Chassis Switch CLI Manual Syntax Description vlanname portlist ip address Specifies a VLAN name. Specifies one or more ports or slots and ports. Specifies the multicast group IP address. Default None. Usage Guidelines Use this command to forward a particular multicast group to VLAN ports. In effect, this command emulates a host on the port that has joined the multicast group. As long as the port is configured with the static entry, multicast traffic for that multicast group is forwarded to that port. This command is for IGMPv2 only. The switch sends proxy IGMP messages in place of those generated by a real host. The proxy messages use the VLAN IP address for source address of the messages. If the VLAN has no IP address assigned, the proxy IGMP message uses 0.0.0.0 as the source IP address. The multicast group should be in the class-D multicast address space, but should not be in the multicast control subnet range (224.0.0.x/24). If the ports also have an IGMP filter configured, the filter entries take precedence. IGMP filters are configured using the command: configure igmp snooping vlan ports filter Example The following command configures a static IGMP entry so the multicast group 224.34.15.37 is forwarded to VLAN marketing on ports 2:1-2:4: configure igmp snooping marketing ports 2:1-2:4 add static group 224.34.15.37 configure igmp snooping vlan ports add static router configure igmp snooping {vlan} ports add static router Description Configures VLAN ports to forward the traffic from all multicast groups, even if no IGMP joins have been received on the port.
