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.
