With the vlan-list argument, you can provide one or more individualVLAN IDs (in the form of vlan-id) and/or one or more VLAN ID ranges (in the form of vlan-id1 to vlan-id2,where vlan-id2 must be greater than vlan-id1). The effective range for a VLAN ID is 1 to 4094 and thetotal number of individual VLANs plus VLAN ranges cannot exceed 10.DescriptionUse the igmp-snooping group-limit command to define the maximum number of multicast groups theport can join.Use the undo igmp-snooping group-limit command to restore the default setting.If you do not specify any VLAN, the command will take effect for all the VLANs to which the current portbelongs; if you specify a VLAN or multiple VLANs, the command will take effect for the port only if theport belongs to the specified VLAN(s). It is recommended to specify a VLAN or multiple VLANs to savememory.By default, the maximum number of multicast groups the port can join is 256.
