Configuring Fast Leave for Member Ports
Context
When the switch receives IGMP Leave messages from a group member port, fast leave allows the switch to immediately delete forwarding entries of the member port but does not reset the aging timer.
Enable fast leave in a VLAN only when each interface in the VLAN is connected to one receiver host.
Fast leave takes effect for member ports in a VLAN only when the switch can process IGMPv2 messages.
Procedure
- Run system-view
The system view is displayed.
- Run vlan vlan-id
The VLAN view is displayed.
- Run igmp-snooping prompt-leave [ group-policy acl-number ]
Fast leave is configured for group member ports in the VLAN.
By default, no member port is allowed to fast leave a multicast group.
If you do not specify group-policy when configuring fast leave, this function takes effect for all groups. For details on how to configure an ACL, see ACL Configuration in the S2720, S5700, and S6700 V200R019C10 Configuration Guide - Security.
