**Table 1** Description of the **display igmp proxy interface** command output
Item	Description
Interface information of VPN-Instance: public net	VPN instance to which IGMP proxy interface information belongs. public net indicates the public network instance.
Vlanif100(192.168.1.2)	Interface type and interface number (IP address).
IGMP proxy is enabled	IGMP proxy is enabled on the interface.
Current IGMP proxy version (negotiated) is 3	Negotiated IGMP version on the IGMP proxy interface is IGMPv3.
Current IGMP proxy version (configured) is 2	IGMPv2 is configured on the IGMP proxy interface.
IGMP proxy state	Status of the IGMP proxy interface, which can be Up or Down.
Value of query interval for IGMP (negotiated)	Query interval negotiated between the query interval configured on the IGMP proxy interface and the query interval carried in a Query message, in seconds. Only IGMPv3 Query messages carry this field. This field takes effect only in IGMPv3.
Value of query interval for IGMP (configured)	Interval at which the IGMP proxy interface sends IGMP Query messages, in seconds.
Value of querier present timeout for IGMPv1	Timeout period of an IGMPv1 querier.
Value of querier present timeout for IGMPv2	Timeout period of an IGMPv2 querier.
Value of querier present timeout for IGMPv3	Timeout period of an IGMPv3 querier.
General query response expiry	Timeout period of a general group query timer.
Querier for IGMP	Address of an IGMP querier. In IGMPv1, a querier is selected based on a multicast routing protocol; in IGMPv2 and IGMPv3, the switch with the lowest IP address acts as the querier on the shared network segment. If no querier exists, this field is displayed as "-".
Robustness (negotiated)	Robustness variable negotiated between the robustness variable configured on an IGMP proxy interface and the robustness variable carried in a Query message. This field takes effect only in IGMPv3.
Robustness (configured)	Robustness variable configured on the IGMP proxy interface.
Require-router-alert	Whether the switch discards IGMP packets that do not contain the Router-Alert option in IP packet headers. enable: The switch discards IGMP packets that do not contain the Router-Alert option in IP packet headers. disable: The switch does not discard IGMP packets that do not contain the Router-Alert option in IP packet headers. This function is configured using the igmp require-router-alert command.
Send-router-alert	Whether the switch sends IGMP packets with the Router-Alert option. enabled: The switch sends IGMP packets with the Router-Alert option. disabled: The switch sends IGMP packets without the Router-Alert option. This function is configured using the igmp send-router-alert command.
Ip-source-policy	Whether to filter IGMP Report/Leave messages based on host addresses. enabled: The switch filters IGMP Report/Leave messages based on host addresses. disabled The switch does not filter IGMP Report/Leave messages based on host addresses. This function is configured using the igmp ip-source-policy command.
Query ip-source-policy	Whether to filter IGMP Query messages based on source addresses. enabled: The switch filters IGMP Query messages based on source addresses. disabled: The switch does not filter IGMP Query messages based on source addresses. This function is configured using the igmp query ip-source-policy command.
TTL-check	Whether the function to check the TTL values in received IGMP Report, Leave, and Query messages is enabled: enabled disabled This function is configured using the igmp ttl-check command.
