Function
The igmp-snooping proxy-uplink-port command configures an IGMP snooping proxy uplink interface. No IGMP Query message can be sent to this interface.
The undo igmp-snooping proxy-uplink-port command deletes an IGMP snooping proxy uplink interface.

undo igmp-snooping proxy-uplink-port vlan vlan-id
Usage Guidelines
Usage Scenario
After IGMP snooping proxy or IGMP snooping querier is enabled in a VLAN, the wireless access controller periodically broadcasts IGMP Query messages to all interfaces in the VLAN, including router ports in the VLAN. This may result in IGMP querier reelection. To prevent IGMP querier reelection, run the igmp-snooping proxy-uplink-port command on the router port to disable the wireless access controller from sending IGMP Query messages to the router port.
Prerequisites
IGMP snooping has been enabled globally using the igmp-snooping enable (system view) command.
Precautions
Only one IGMP snooping proxy uplink interface can be configured in a VLAN.
