Parameters
limit: Maximum number of multicast groups the port can join, in the range of 1 to 512.
overflow-replace: Allows a new multicast group to replace an existing multicast group with the lowest
IP address.
vlan vlan-list: Specifies a VLAN list. With the vlan-list argument, you can provide one or more individual
VLAN 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 the
total number of individual VLANs plus VLAN ranges cannot exceed 10.
Description
Use the igmp-snooping group-limit command to define the maximum number of multicast groups the
port 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 port
belongs; if you specify a VLAN or multiple VLANs, the command will take effect for the port only if the
port belongs to the specified VLAN(s). It is recommended to specify a VLAN or multiple VLANs to save
memory.
For the S3100-SI series, the system default is 256. For the S3100-EI series, the system default is 512.
