Configure Multicast Stream Limitation on an Ethernet Port

Configure multicast stream limitation on an Ethernet port to limit the number of concurrent multicast streams on the port. By limiting the number of concurrent multicast streams, providers 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 port drops joins to new streams. A service provider uses this feature to control the overall bandwidth usage in addition to restricting users from attaching more than the allowed television sets to a link.

Note

Note

Configuration of multicast stream limitation is not supported on a node configured as the DvR Leaf within a DvR domain.

Procedure

  1. Enter GigabitEthernet Interface Configuration mode:

    enable

    configure terminal

    interface GigabitEthernet {slot/port[/sub-port][-slot/port[/sub-port]][,...]}

    Note

    Note

    If the platform supports channelization and the port is channelized, you must also specify the sub-port in the format slot/port/sub-port.

  2. Enable multicast stream limitation and configure the maximum number of allowed streams:

    ip igmp stream-limit stream-limit-max-streams <0-65535>

  3. If stream-limit is already enabled on the interface, change the maximum number of allowed streams:

    ip igmp stream-limit stream-limit-max-streams <0-65535>

  4. Display multicast stream limitation information for the ports on a specific interface:

    show ip igmp stream-limit interface

Example

Enable multicast stream limitation on the Ethernet port and configure the maximum number of allowed streams to 8.

Switch:1(config-if)# ip igmp stream-limit
Switch:1(config-if)# ip igmp stream-limit stream-limit-max-streams 8

Variable definitions

Use the data in the following table to use the ip igmp stream-limit-max-streams command.

Variable

Value

<0-65535>

Configures the maximum number of allowed streams on this port. The range is from 0–65535 and the default is 4.
