Unknown
Multicast Groups
Configure the way in which the switch processes data that are sent to unknown
multicast groups as Forward or Discard. By default, it is Forward.
Unknown multicast groups are multicast groups that do not match any of the
groups announced in earlier IGMP membership reports, and thus cannot be
found in the multicast forwarding table of the switch.
Note:
IGMP Snooping and MLD Snooping share the setting of Unknown
Multicast Groups, so you have to enable IGMP Snooping globally on the L2
FEATURES > Multicast > IGMP Snooping > Global Config page at the same
time.
