Configuring Fast Leave for Member Ports
Context
The fast leave function enables a switch to delete the multicast forwarding entry corresponding to an interface immediately after the interface receives a Done message, without waiting for aging of the forwarding entry.
When each interface in a VLAN is connected to only one host, you can enable fast leave in the VLAN.
Procedure
- Run system-view
The system view is displayed.
- Run vlan vlan-id
The VLAN view is displayed.
- Run mld-snooping prompt-leave [ group-policy acl6-number ]
Fast leave is enabled.
By default, fast leave is disabled.
If you do not specify group-policy when configuring the fast leave function, this function takes effect for all groups. To specify a group policy in the command, create an ACL and configure rules for the ACL before running the command. For details about ACL configuration, see ACL Configuration in the S2720, S5700, and S6700 V200R019C10 Configuration Guide - Security.
