Parameters

Parameter	Description	Value
vlan [ vlan-id ]	Displays IGMP snooping statistics in a specified VLAN. If vlan-id is not specified, the system displays IGMP snooping statistics in all VLANs. If vlan-id is specified, the system displays statistics about IGMP messages in the specified VLAN, but does not display the counts of IGMP snooping events that occur in the VLAN.	The value is an integer that ranges from 1 to 4094.

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, 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.
