Configuring Fast Leave Mode
Configure fast leave mode to control all IGMP fast leave enabled interfaces.
Before you begin
-
You must enable explicit-host-tracking before configuring fast-leave mode. To enable explicit-host-tracking, see Configuring IGMP parameters on a port and Configuring IGMP parameters on a VLAN.
About this task
Fast leave relies on an alternative leave process where the switch stops sending traffic for the group immediately after it receives a leave message, without issuing a query to check if other group members exist on the network. Use this global parameter to alter the leave processing on fast leave enabled IGMPv2, IGMPv3, and IGMP snoop interfaces.
Important
Fast leave mode applies only to fast leave enabled IGMP interfaces.
You can configure IGMP on a VRF instance the same way you configure the Global Router except that you must first launch the appropriate VRF context.
Procedure
- In the navigation pane, expand the following folders: .
- Click IGMP.
- Click the Global tab.
- Select the mode.
