Usage Guidelines
Usage Scenario
After completing IGMP snooping configuration, you can use the display igmp-snooping statistics command to view IGMP snooping statistics, including the number of IGMP messages sent, number of IGMP messages received, and number of PIM Hello messages received in each VLAN, and number of Layer 2 events that have occurred in all VLANs. Layer 2 events include changes in interface status, changes in VLAN status, changes in VLAN member interfaces (interfaces join or leave VLANs), and MSTP events. When a multicast fault occurs, the IGMP snooping statistics help you identify the cause of the fault.
Precautions
This command displays IGMP snooping statistics only when IGMP snooping has been enabled globally using the igmp-snooping enable (VLAN view) command.
