Add or remove blocked multicast address
ranges
Multicast host groups are identified by class D IP addresses, which range from 224.0.0.0
to 239.255.255.255. You can block one, several, or all of these multicast address ranges,
which you then can apply to one or more ports. The switch does not let traffic from a
blocked address pass through.
Note: If you want remove a blocked multicast range from a port, we recommend that
you set the multicast mode for the port to default mode rather than remove the blockage
for the multicast range. For more information, see Configure the multicast mode for
one or more ports on page 42.
