TL-SL5428E 24-port 10/100Mbps + 4-port Gigabit L2 Managed Switch CLI Guide id -- IP-range ID, ranging from 1 to 30. start-ip -- The start multicast IP of the IP-range. end-ip -- The end multicast IP of the IP-range. Command Mode Global Configuration Mode Example Modify the multicast IP-range whose ID is 20 as 225.0.0.10~225.0.0.12: TP-LINK(config)# igmp filter- config 20 225.0.0.10 225.0.0.12 igmp filter Description The igmp filter command is used to configure Port Filter. To return to the default configuration, please use no igmp filter command. When the switch receives IGMP report message, it examines the multicast filtering IP ID configured on the access port to determine if the port can join the multicast group. If the multicast IP is not filtered, the switch will add the port to the forward port list of the multicast group. Otherwise, the switch will drop the IGMP report message. In that way, you can control the multicast groups that users can access. Syntax igmp filter [ state [disable | enable] | mode [refuse | accept] | addr-id [filter-addr-id] | maxgroup [max-group] ] no igmp filter Parameter state -- Enable/ Disable port multicast filtering function. By default, it is disabled. mode -- Action Mode, with refuse and accept options. Refuse indicates only the multicast packets whose multicast IP is not in the IP-range will be processed, while accept indicates only the multicast packets whose multicast IP is in the IP-range will be processed. By default, the option is accept. filter-addr-id -- The IP-range ID the port will be bound to, in the format of 1-3, 4, 6. Up to 5 IP-Ranges can be bound to one port. max-group -- The maximum number of multicast groups for the port to join in. It is used to prevent some ports taking up too much bandwidth. Command Mode 166
