DGS-1520 Series Gigabit Ethernet Smart Managed Switch CLI Reference Guide Command Default Level Level: 12. Usage Guideline By default, the IGMP report or leave messages received by the interface will be checked to determine whether its source IP is in the same network as the interface. If they are not in the same network, the message information won't be learned by the IGMP protocol. Use the ip igmp ignore-subscriber-ip-check command to disable the source IP check. If the check is disabled, the IGMP report or leave message with any source IP will be processed by the IGMP protocol. Example This example shows how to disable the subscriber's source IP check on VLAN 1. Switch#configure terminal Switch(config)#interface vlan1 Switch(config-if)#ip igmp ignore-subscriber-ip-check Switch(config-if)# 42-4 ip igmp last-member-query-interval This command is used to configure the interval at which the router sends IGMP group-specific or group-sourcespecific (channel) query messages. Use the no form of the command to revert to the default setting. ip igmp last-member-query-interval SECONDS no ip igmp last-member-query-interval Parameters SECONDS Specifies the interval at which IGMP group-specific host query messages are sent. The range is from 1 to 25. Default By default, this value is 1 second. Command Mode Interface Configuration Mode. Command Default Level Level: 12. Usage Guideline When the router receives a leave message from a receiver to claim leave from a group or a channel, the router will send the group specific query or group-source specific query message to the receiver interface. The IGMP lastmember query interval will be advertised in the query message and conveyed to the receiver. This command configures the period that the router will send the next group-specific query or group-source specific query message if there is no report from receiver for the specific group or specific channel. The router will retry for the last member query count. If there is no report messages received after the retry count, the interface will be removed the membership from the specific group or specific channel. 454
