7.4 Example for Configuring Multicast Filtering
7.4.1 Network Requirements
Host B, Host C and Host D are in the same subnet. Host C and Host D only receive multicast
data sent to 225.0.0.1, while Host B receives all multicast data except the one sent from
225.0.0.2.
7.4.2 Configuration Scheme
With the functions for managing multicast groups, whitelist and blacklist mechanism (profile
binding), the switch can only allow specific member ports to join specific multicast groups
or disallow specific member ports to join specific multicast groups. You can achieve this
filtering function by creating a profile and binding it to the corresponding member port.
