Configuring multicast stream limitation on an interface

Configure multicast stream limitation to limit the number of concurrent multicast streams on the interface. By limiting the number of concurrent multicast streams, you can protect the bandwidth on a specific interface and control access to multicast streams.

About this task

You can configure the maximum number of streams independently. After the number of streams reaches the limit, the interface drops additional join reports for new streams. You can control the overall bandwidth usage in addition to restricting users from receiving more than a specific limit of multicast streams on an interface.

You can configure IGMP on a VRF instance the same way you configure the Global Router except that you must first launch the appropriate VRF context.

Procedure

In the navigation pane, expand the following folders: Configuration > IP.
Click IGMP.
Click the StreamLimit tab.
To change the status of an interface, double-click on the StreamLimitEnable field for the interface, and then select enable or disable from the menu. If the interface is enabled, you can edit the Maximum Number of Stream field.
Click Apply.
