66-14 config [igmp_snooping | mld_snooping] multicast_vlan
forward_unmatched
Description
This command is used to configure the forwarding mode for multicast VLAN unmatched packets.
When the Switch receives an IGMP/MLD snooping packet, it will match the packet against the
multicast profile to determine which multicast VLAN to associate with. If the packet does not match
all profiles, the packet will be forwarded or dropped based on this setting.
By default, the packet will be dropped.
Format
config [igmp_snooping | mld_snooping] multicast_vlan forward_unmatched [enable |
disable]
Parameters
igmp_snooping - Specify that the IGMP snooping multicast VLAN function will be configured.
mld_snooping - Specify that the MLD snooping multicast VLAN function will be configured.
multicast_vlan forward_unmatched - Specify to enable or disable packet flooding on the
multicast VLAN.
enable - The packet will be flooded on the VLAN.
disable - The packet will be dropped.
Restrictions
Only Administrator, Operator and Power-User level users can issue this command.
