GS716Tv2 and GS724Tv3 Software Administration Manual To access the IGMP Snooping VLAN Configuration page: 1. Click Switching Multicast IGMP Snooping IGMP Snooping VLAN Configuration in the navigation tree. Figure 3-26 Table 3-24. IGMP Snooping VLAN Configuration Fields Field VLAN ID Fast Leave Admin Mode Host Timeout Description List of VLAN IDs for which IGMP Snooping is enabled. Enable or disable the IGMP Snooping Fast Leave Mode for the specified VLAN ID. Enabling fast-leave allows the switch to immediately remove the layer 2 LAN interface from its forwarding table entry upon receiving an IGMP leave message for that multicast group without first sending out MAC-based general queries to the interface. You should enable fast-leave admin mode only on VLANs where only one host is connected to each layer 2 LAN port. This prevents the inadvertent dropping of the other hosts that were connected to the same layer 2 LAN port but were still interested in receiving multicast traffic directed to that group. Also, fast-leave processing is supported only with IGMP version 2 hosts. Sets the value for group membership interval of IGMP snooping for the specified VLAN ID. The valid range is (Maximum Response Time + 1) to 3600 seconds. Configuring Switching Information v1.0, July 2009 3-41
