1.1.10 igmp-snooping nonflooding-enable
Syntax
igmp-snooping nonflooding-enable
undo igmp-snooping nonflooding-enable
View
System view
Parameters
None
Description
Use the
igmp-snooping nonflooding-enable
command to enable the IGMP
Snooping non-flooding function. With this function enabled, unknown multicast packets
are passed to the router ports of the switch rather than being flooded in the VLAN.
Use the
undo
igmp-snooping nonflooding-enable
command to disable the IGMP
Snooping non-flooding function.
By default, the IGMP Snooping non-flooding function is disabled, namely unknown
multicast packets are flooded in the VLAN.
The difference between the IGMP Snooping non-flooding function and the function of
dropping unknown multicast packets is in that the former passes unknown multicast
packets to the router ports while the latter directly discards unknown multicast packets.
You can configure this command only after IGMP Snooping is enabled globally. When
IGMP Snooping is disabled globally, the configuration of the
igmp-snooping
nonflooding-enable
command is also removed.
