Igmp-Snooping Nonflooding-Enable - H3C s3600 series Command Manual

Description
Use the igmp-snooping max-response-time command to configure the maximum response time in
IGMP general queries.
Use the undo igmp-snooping max-response-time command to restore the default.

An appropriate setting of the maximum response time in IGMP queries allows hosts to respond to
queries quickly and thus the querier can learn the existence of multicast members quickly.

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.
