Parameters

vpn-instance vpn-instance-name: Specifies an MPLS L3VPN instance by its name, a case-sensitive string of 1 to 31 characters. If you do not specify a VPN instance, this command displays IGMP information for interfaces on the public network.

interface-type interface-number: Specifies an interface by its type and number. If you do not specify an interface, this command displays IGMP information for all IGMP-enabled interfaces.

host: Displays information about the interfaces enabled with the IGMP host feature. If you do not specify this keyword, the command displays IGMP information for interfaces enabled with IGMP and those enabled with the IGMP host feature. For more information about the IGMP host feature, see VXLAN Configuration Guide.

proxy: Displays the IGMP proxy interface information. If you do not specify this keyword, the command displays IGMP information about all interfaces.

verbose: Displays detailed IGMP information.

Table 35: Command output

Field	Description
Vlan-interface1(10.10.1.20)	Interface and its IP address.
IGMP is enabled	IGMP is enabled on the interface.
IGMP version	Version of IGMP that the interface runs.
Query interval for IGMP	IGMP general query interval, in seconds.
Other querier present time for IGMP	IGMP other querier present interval, in seconds.
Maximum query response time for IGMP	Maximum response time for IGMP general queries, in seconds.
Last member query interval	Interval for sending IGMP group-specific queries or IGMP group-and-source-specific queries, in seconds.
Last member query count	Number of IGMP group-specific queries or IGMP group-and-source-specific queries sent for the multicast group.
Startup query interval	Interval for sending IGMP general queries on startup, in seconds.
Startup query count	Number of IGMP general queries that the device sends on startup.
General query timer expiry	Remaining time for the IGMP general query timer. This field displays Off if the timer is disabled.
Querier for IGMP	NOTE:	IP address of the IGMP querier. This field is not displayed when the device runs IGMPv1 and the device is not the IGMP querier. In IGMPv1, the PIM DR acts as the IGMP querier. You can use the display pim interface command to display PIM information.
No querier elected	NOTE:	No IGMP querier election is performed. This field is displayed when the device runs IGMPv1 and is not the IGMP querier. In IGMPv1, the PIM DR acts as the IGMP querier. You can use the display pim interface command to display PIM information.
IGMP activity: 1 join(s), 0 leave(s)	Statistics of IGMP activities: join(s)—Total number of multicast groups that this interface has joined. leave(s)—Total number of multicast groups that this interface has left.
Multicast routing on this interface	Whether IP multicast routing is enabled: Enabled or Disabled.
Robustness	Robustness variable of the IGMP querier.
Require-router-alert	Whether the feature of dropping IGMP messages without Router-Alert is enabled: Enabled or Disabled,
Fast-leave	Whether the fast-leave processing feature is enabled: Enabled or Disabled.
Startup-query	Whether the IGMP querier sends IGMP general queries at the startup query interval on startup: On—The IGMP querier performs the above action. Off—The IGMP querier does not perform the above action.
Other-querier-present-timer-expiry	Remaining time for the other querier present timer. This field displays Off if the timer is disabled.
IGMP groups reported in total	Total number of multicast groups that the interface has joined dynamically. This field is not displayed if the interface does not join multicast groups.
IGMP proxy is enabled	IGMP proxying is enabled on the interface.
IGMP host is enabled	The IGMP host feature is enabled on the interface.
Version1-querier-present-timer-expiry	Remaining time for the IGMPv1 querier present timer. This field displays Off if the timer is disabled.
