When IGMP snooping is enabled for Dynamic Host Control Protocol (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.
You can configure the switch to delete the IGMP snooping entry of a DHCP snooping user immediately after the user goes offline, so that the multicast flow requested by the user is immediately terminated.
For details about DHCP snooping, see DHCP Snooping Configuration in the S2720, S5700, and S6700 V200R019C10 Configuration Guide - Security.
