IGMP Snooping
The settings in the IGMP Snooping feature of the EtherWAN switch controls how the switch
forwards multicast packets.
General Overview
The EX24000 Switch has been outfitted with the IGMP Snooping function in three modes:
Disabled:
o
The switch will forward all multicast packets according to the
Forced
Forwarding Port
setting based on the following rule:
All multicast packets will be forwarded to only the port specified by
either the
PassiveForwardMode
or the
ForcedForwardMode
function.
Passive mode:
o
The switch will forward any multicast packets that have known receivers to
the known multicast receiver ports only.
o
The switch will forward any unknown multicast packets (multicast packets
without any known receivers) according to the
Forced Forwarding Port
setting based on the following rule:
When there is no Querier Port (a port that receives IGMP queries)
present all unknown multicast packets will be forwarded to the port
specified by either the
PassiveForwardMode
function or the
ForcedForwardMode
function.
When there is a Querier port present, the switch will forward all
unknown multicast packets to the Querier port. In addition, all
unknown multicast packets will be forwarded to the port specified by
the
ForcedForwardMode
function as well.
Querier mode:
o
The switch will forward any multicast packets that have known receivers to
the known multicast receiver ports only.
