Command:
ipv6 mld snooping vlan <

VLAN ID, the valid range is <1-4094>
g_limit:
<1-65535>, max number of groups joined

<1-65535>, max number of source entries in each group, consisting of include source and exclude source
Command Mode:
Global Mode
Default:
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, MLD snooping must be enabled on VLAN
. The “no” form of this command
re
stores 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 MLD is in operation, please make this configuration in
accordance with the MLD configuration as possible.
Example:
Switch(config)#ipv6 mld snooping vlan 2 limit group 300
