Gigabit Ethernet Smart Managed Plus Switches By default, the VLAN ID is 1. You can specify a VLAN for IGMP snooping only if you enabled port-based or 802.1Q-based VLANs (see Use VLANS for Traffic Segmentation on page 27). IGMP snooping functions only on the VLAN that is specified in the VLAN ID Enabled for IGMP Snooping field. 8. (Optional) Select the Validate IGMPv3 IP header Enable radio button. Some network devices might not conform to the IGMPv3 standard. When the Validate IGMPv3 IP header option is enabled, IGMP messages are required to include TTL = 1, ToS Byte = 0xC0 (Internetwork Control), and the router alert IP option (9404) must be set. Otherwise, the packets are ignored. 9. (Optional) Select the Block Unknown MultiCast Address Enable radio button. When this feature is enabled, multicast packets are forwarded only to the ports that are in the multicast group learned from IGMP snooping. All unknown multicast packets are dropped. 10. (Optional, for some models only) Select an option from the IGMP Snooping Static Router Port menu. You can select a port to be the dedicated IGMP snooping static router port if no IGMP query exists in the network for the switch to discover the router port dynamically. After a port is selected as the static router port, all IGMP Join and Leave reports are forwarded to the port. 11. Click the Apply button. Your settings are saved. Specify a VLAN for IGMP Snooping You can specify a VLAN for IGMP snooping only if you enabled port-based or 802.1Q-based VLANs (see Use VLANS for Traffic Segmentation on page 27).
