IGMP snooping increases resource utilization by forwarding multicast packets and increases network security by restricting user access.
Enabling the IGMP Snooping Protocol
The IGMP Snooping can constrain the multicast on the Layer 2 Ethernet switch to manage and control multicast groups. Through the multicast forwarding, resources utilization can be improved. Through limitations on user access, the network security is improved.
Configuring the Aging Time for the Multicast Router Port
If the IGMP Snooping subsystem fails to receive any query packet at the router port before the aging timer of the router port times out, the IGMP Snooping subsystem regards that the router port is invalid.
Querying the Multicast Router Ports
The router port refers to the port that faces the multicast router. The Ethernet data board regards the port that receives the IGMP query packets as the router port.
