Usage Guidelines

Usage Scenario

By default, when IGMP snooping is enabled for DHCP snooping users, the switch does not delete the IGMP snooping entry of a user immediately after the user goes offline. The multicast flow requested by the user is still transmitted until the IGMP snooping entry of the user is aged out.

The dhcp-snooping user-offline remove igmp-snooping command enables the switch to delete the IGMP snooping entry of a DHCP snooping user immediately after the user goes offline, terminating the multicast flow requested by the user.

Prerequisites

IGMP snooping has been enabled globally using the igmp-snooping enable (system view) command.
