Accton Technology ES3528M-SFP manual Enabling Igmp Filtering and Throttling

Multicast Filtering 3

IGMP throttling sets a maximum number of multicast groups that a port can join at the same time. When the maximum number of groups is reached on a port, the switch can take one of two actions; either “deny” or “replace”. If the action is set to deny, any new IGMP join reports will be dropped. If the action is set to replace, the switch randomly removes an existing group and replaces it with the new multicast group.

Note: IGMP filtering and throttling only applies to dynamically learned multicast groups. It does not apply to statically configured groups.

Enabling IGMP Filtering and Throttling

To implement IGMP filtering and throttling on the switch, you must first enable the feature globally and create IGMP profile numbers.

Command Attributes

•IGMP Filter – Enables IGMP filtering and throttling globally for the switch. (Default: Disabled)

•IGMP Profile – Creates IGMP profile numbers. (Range: 1-4294967295)

Web – Click IGMP Snooping, IGMP Filter Configuration. Create a profile group by entering a number in the text box and clicking Add. Enable the IGMP filter status, then click Apply.
