By default, no IPv6 group filter is
configured for the port, and the
hosts on the port can join any valid
IPv6 multicast group.
Configuring IPv6 multicast source port filtering
After the IPv6 multicast source port filtering feature is enabled on a port, the port can connect to only
IPv6 multicast receivers rather than multicast sources. The reason is that the port denies all IPv6
multicast data packets but it permits multicast protocol packets.
If this feature is disabled, the port can connect to both multicast sources and IPv6 multicast
receivers.

Enabling dropping unknown IPv6 multicast data
Unknown IPv6 multicast
data refers to IPv6 multicast data for which no forwarding entries exist in the
MLD snooping forwarding table. When the switch receives such IPv6 multicast traffic, one of the
following occurs:
