FS728TP Smart Switch Software Administration Manual IGMP Snooping VLAN Configuration Use the IGMP Snooping VLAN Configuration page to configure IGMP snooping settings for VLANs on the system. To access the IGMP Snooping VLAN Configuration page, click Switching Multicast  IGMP Snooping  IGMP Snooping VLAN Configuration. To configure IGMP snooping settings for VLANs: 1. To enable IGMP snooping on a VLAN, enter the VLAN ID in the appropriate field and configure the IGMP Snooping values: • Fast Leave Admin Mode. 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. • Host Timeout. 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. • Maximum Response Time. Enter the amount of time in seconds that a switch will wait after sending a query on the VLAN because it did not receive a report for a particular group in that interface. value. The valid range is 1 to 25 seconds. Its value must be less than the Host Timeout value. • MRouter Timeout. Enter the amount of time that a switch will wait to receive a query on the VLAN before removing it from the list of VLANs with multicast routers attached.
