Configure Multicast Stream Limitation on an Ethernet Port

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

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

1. Enter GigabitEthernet Interface Configuration mode:

   enable

   configure terminal

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

   

   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
