DGS-1250 Series Gigabit Ethernet Smart Managed Switch CLI Reference Guide Example This example shows how to enable IGMP snooping fast-leave on VLAN 1. Switch# configure terminal Switch(config)# vlan 1 Switch(config-vlan)# ip igmp snooping fast-leave Switch(config-vlan)# 29-4 ip igmp snooping last-member-query-interval This command is used to configure the interval at which the IGMP snooping querier sends IGMP group-specific or group-source-specific (channel) query messages. Use the no form of this command to revert to the default setting. ip igmp snooping last-member-query-interval SECONDS no ip igmp snooping last-member-query-interval Parameters SECONDS Specifies the maximum amount of time between group-specific query messages, including those sent in response to leave-group messages. The range of this value is 1 to 25. Default By default, this value is 1 second. Command Mode VLAN Configuration Mode. Usage Guideline This command is only available for VLAN interface configuration. On receiving an IGMP leave message, the IGMP snooping querier will assume that there are no local members on the interface if there are no reports received after the response time. Users can lower this interval to reduce the amount of time it takes a switch to detect the loss of the last member of a group. Example This example shows how to configure the last member query interval time to be 3 seconds. Switch# configure terminal Switch(config)# vlan 1000 Switch(config-vlan)# ip igmp snooping last-member-query-interval 3 Switch(config-vlan)# 29-5 ip igmp snooping mrouter This command is used to configure the specified interface(s) as the multicast router ports or as forbidden to be multicast router ports on the Switch. Use the no form of this command to remove the interface(s) from router ports or forbidden multicast router ports. ip igmp snooping mrouter {interface INTERFACE-ID [, | -] | forbidden interface INTERFACE-ID [, | -]} no ip igmp snooping mrouter {interface INTERFACE-ID [, | -] | forbidden interface INTERFACE-ID [, | -]} 225
