Multicast
By default, multicast traffic is enabled on all networks available under the Access Networks. Multicast traffic is efficient as the server sends the data packets and the switches and routers only forward the data packets to the group of recipients.
Therefore, the load over the server and the network traffic decreases.
The user can disable and enable the multicast traffic on one or multiple networks.
