IGMP_ENABLED
Description
Get or Set the IGMP Enabled configuration.
Because the L2/L3 device will flood the multicast packets to all of ports they have, it will waste lots of bandwidth when there are multicast streams go through them. There are networking protocols to helps these devices to be smarter to handle multicast streams. The IGMP is a protocol helps the L2/L3 device to learn how to forward multicast streams.
This URL only takes effect if only if the device is in the multicasting mode. Then, the encoder will send the IGMP V2 Query packet periodically to the network. The remote host interested in this multicast stream will reply the Query. If the L2/L3 device understands the IGMP, it could learn which port it should forward the multicast stream.
If the CHANNEL=n was set with this URL to the Multi-Channel device, this command is read-only command and the Router's IGMP_ENABLED configuration will be returned.
