PLANET WGSW-52040 - Manual (Page 570)

35-110
Maximum 50 groups by default, with each group capable with 40 source entries.
Usage Guide:
When number of joined group reaches the limit, new group requesting for
joining in will be rejected for preventing hostile attacks. To use this command, IGMP snooping must be enabled on
VLAN. The “no” form of this command restores the default other than set to “no limit”. For the safety considerations,
this command will not be configured to “no limit”. It is recommended to use default value and if layer 3 IGMP is in
operation, please make this configuration in accordance with the IGMP configuration as possible.

Switch(config)#ip igmp snooping vlan 2 limit group 300
