6.2.3 Configuring IGMP Multicast Groups on the Interface
You can perform the following configurations on the interface for the IGMP multicast
groups:
z Limit the number of joined multicast groups
z Limit the range of multicast groups that the interface serves
I. Limit the number of joined multicast groups
If the number of joined IGMP groups on the multicast routing interface of the switch is
not limited, the memory of the switch may be used out and the routing interface of the
switch may fail when plenty of multicast groups join in the routing interface.
You can configure limit on the number of joined IGMP multicast groups on the interface
of the switch. Thus, when users are ordering the programs of multicast groups, the
network bandwidth can be controlled because the number of multicast groups is
limited.
II. Limit the range of multicast groups that the interface serves
The Layer 3 switch determines the membership of the network segment through
translating the received IGMP join packets. You can configure a filter for each interface
to limit the range of multicast groups that the interface serves.
