\[purpose] enable igmp snooping for the vlan \[view] vlan view \[notes] the igmp snooping function operates on the layer 2 switching network between the router and user terminals it maintains the multicast forwarding table by listening to multicast protocol messages sent from the router and user terminals, thereby enabling multicast packets to be broadcast between designated interfaces within the vlan \[use cases] sonic(config)# vlan 100 sonic(config vlan 100)# igmp snooping enable igmp snooping version igmp snooping version 1 3 \[command] igmp snooping version 1 3 \[purpose] configure

description interface name interface name limit value range 1–4094 \[view] vlan view \[notes] after modifying the maximum number of entries an interface can learn, any entries exceeding the limit will be learned into the igmp process memory space but will not be installed (i e , not delivered to hardware) additionally, these entries will not be relearned within their aging cycle \[use cases] sonic(config)# vlan 100 sonic(config vlan 100)# mcast snooping group limit ethernet 10 4094 igmp snooping proxy enable igmp snooping proxy enable \[command] igmp snooping proxy enable \[purpose] enable igmp snooping proxy \[view] vlan view \[notes] after enabling the igmp snooping proxy function, the device can send igmp query messages on behalf of the router and receive igmp report/leave messages from users, thereby reducing the load on the routing device when a large number of terminals exist in the network \[use cases] sonic(config)# vlan 100 sonic(config vlan 100)# igmp snooping proxy enable igmp snooping querier enable igmp snooping querier enable \[command] igmp snooping querier enable \[purpose] enable igmp querier functionality \[view] vlan view \[notes] configuring the querier on the device allows it to send igmp query messages on behalf of the upstream device the device will periodically send igmp query packets to all interfaces (including router ports) within the vlan if an igmp querier already exists in the multicast network, this may trigger a re election of the igmp querier \[use cases] sonic(config)# vlan 100 sonic(config vlan 100)# igmp snooping querier enable igmp snooping querier ip igmp snooping querier ip ip address \[command] igmp snooping querier ip ip address \[purpose] configure the source ip address of igmp query packets \[view] vlan view \[notes] when multiple queriers exist within the network, the selection of the querier can be controlled by modifying the ip address of the device's query packets \[use cases] sonic(config)# vlan 100

fast leave enable \[purpose] enable fast leave for member ports \[view] vlan view \[notes] when an igmp leave message is received from a host leaving a specific multicast group, the device will immediately delete the corresponding multicast forwarding entry for that host without sending a group specific query \[use cases] sonic(config)# vlan 100 sonic(config vlan 100)# igmp snooping fast leave enable igmp snooping robustness igmp snooping robustness 1 255 \[command] igmp snooping robustness 1 255 \[purpose] configure the robustness variable \[view] vlan view \[notes] this command adjusts robustness in the following two ways it adjusts the number of group specific query messages sent by the querier to avoid potential network packet loss when an igmp leave message for a multicast group is received from a user, the querier sends the configured number of group specific query messages to inquire whether any members remain in that multicast group it adjusts the member aging time after a port receives a report message from a downstream host, it sets the member aging time as (number of group specific query messages × general query interval) + maximum response time for downstream hosts to reply to the querier \[use cases] sonic(config)# vlan 100 sonic(config vlan 100)# igmp snooping robustness 100 igmp snooping query interval igmp snooping query interval 1 18000

discrete values or as a continuous range using a hyphen \[view] system configuration view \[notes] when users in different vlans need to receive data from the same multicast source, the device must replicate the data stream for each vlan in this scenario, efficient forwarding can be achieved by configuring a multicast vlan configure the vlans where the users reside as user vlans, and configure the vlan to which the router interface belongs as the multicast vlan data is then unidirectionally replicated from the multicast vlan to each user vlan this configuration takes effect only when igmp
