GPON ONT Service Profile Configuration-----multicast mode(gpon profile)

Function

This command is used to set the multicast mode of the ONT in a GPON ONT service profile. In different multicast modes, the multicast program streams are processed in different ways and the multicast users are authenticated in different ways. If you require the ONT to maintain the multicast forwarding table, select the igmp-snooping mode. If you require the OLT to maintain the ONT multicast forwarding table, select the olt-control mode. If the ONT does not support the multicast mode or the OLT does not specify the ONT multicast mode, select the unconcern mode.

Format

multicast mode mode-value

Parameters

Parameter	Description	Value
mode-value	Indicates the multicast mode. The following three modes are supported: igmp-snooping: Indicates the uncontrollable multicast. In this mode, the user reports the report packet to the OLT and then can watch the multicast programs without receiving the multicast configurations from the OLT. The ONT obtains relevant information and maintains multicast forwarding entries of the ONT by listening to (snooping) the IGMP packets. In this case, the OLT authentication is not required, while the encryption system of the IPTV platform controls the multicast program rights and the third-party device (such as the set-top box) controls whether a user has the right to watch a program. olt-control: Indicates the dynamic controllable multicast. In this mode, the report packet sent from the user is authenticated on the OLT. After the report packet passes the authentication, the OLT issues the multicast configurations to the ONT. Then, the user can watch the multicast programs. The OLT fully controls the multicast program rights. Unconcern: Indicates that the multicast mode is not concerned. That is, the OLT does not specify the multicast mode of the ONT. In this mode, if the ONT supports configuring of the multicast mode, the multicast mode of the ONT uses the default setting or the latest setting configured on the OLT.	Enumerated type. Option: igmp-snooping, olt-control, and unconcern. Default value: unconcern.

Usage Guidelines

• Run the config command to enter global config mode, and then run the ont-srvprofile gpon command to enter GPON ONT service profile mode.
• Different ONT multicast modes require different OMCI messages sent from the OLT. In olt-control mode, the Huawei proprietary OMCI message (the ONT is required to support this OMCI message) is sent from the OLT. In igmp-snooping mode, the standard OMCI message is sent from the OLT. In unconcern mode, no OMCI message is sent from the OLT.
• After running this command, you need to run the commit command. Then, the configuration performed through this command can take effect.
• You can run the display ont-srvprofile gpon command to query the multicast mode of the GPON ONT.

Example

To configure the multicast mode of ONT service profile 10 to olt-control to prevent the problem wherein after one multicast user with rights orders a program, all the users on the GPON port receive the program, do as follows:

huawei(config-gpon-srvprofile-10)#multicast mode                    
{ mode-value<E><igmp-snooping,olt-control,unconcern> }:olt-control                                   
                                                                                
  Command:
          multicast mode olt-control

huawei(config-gpon-srvprofile-10)#commit
