ProSAFE 8-Port and 16-Port Gigabit Web Managed Click Switch
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) Select any item in 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
it. Only some switch models support any setting in this field.
11. Click the APPLY button.
Your settings are saved.
