Function Description
Multicast refers to the point-to-multipoint communication between a certain node and all other nodes in the network. The core of the multicast technology is to duplicate the packets at the place nearest to the receiver, thus lowering the multicast traffic on the network.Controllable multicast allows an access device to determine if a user has the authority to watch programs by identifying the user request packets. In this way, the access device controls and forwards the multicast services. The MA5680T/MA5683T/MA5608T provides the IPTV service by using the multicast technology. By using controllable multicast, the access device manages and controls multicast users. This helps to meet the requirements of the carriers for video services provisioning, and to enable the multicast services to be operable and manageable.
Function
This command is used to query the information about the members in a
multicast VLAN, or the information about the multicast VLAN pertaining to the
multicast members. When you need to know the mapping between multicast users and
multicast VLANs, run this command.
Format
display igmp multicast-vlan member { service-port
index | port frameid/slotid/portid [
gemport gemport-id ] | vlan
vlanid }
Parameters
| Parameter | Description | Value |
|---|---|---|
| port frameid/slotid/portid | Indicates the subrack ID, slot ID, and port ID. Enter a slash (/) between the subrack, slot, and port IDs. When you need to set the multicast VLANs to which multicast users belong based on the port ID, use this parameter. | Please see Differences Between Shelves. |
| service-port index | Indicates the ID of the service port. |
Numeral type,Range:
|
| gemport gemport-id | GEM port number. GEM ports of each PON port are numbered in a centralized way. GEM ports 0-127 are reserved for the private use of OMCI and GEM ports 4000-4095 serve as channels for special use. | Numeral type. Range: 128-3999. |
| vlan vlanid | Indicates the multicast VLAN ID. When you need to query all members in a multicast VLAN based on VLAN ID, use this parameter. | Numeral type. Range: 1-4093. |
Modes
Privilege mode, BTV mode, MVLAN mode
Level
Operator level
Usage Guidelines
- Run the config command to enter global config mode, and then run the btv command to enter BTV mode.
- Run the config command to enter global config mode, and then run the multicast-vlan command to enter MVLAN mode. Or in BTV mode, run the multicast-vlan command to enter MVLAN mode.
- Only a multicast user can be added as the member of a multicast VLAN by running command igmp multicast-vlan member(profile-mode). You can run the display igmp user(profile-mode) command to query the information about a multicast user.
Example
To query the multicast VLAN to which the multicast users at port 0/3/0 belong, do as follows:
huawei#display igmp multicast-vlan member port 0/3/0
User service port: 10
Multicast VLAN(s) the user joined :
-------------------------------------------------
100
-------------------------------------------------
Total: 1
To query all the multicast user members in multicast VLAN 20, do as
follows:huawei#display igmp multicast-vlan member vlan 20
BTV user(s) that join(s) the multicast VLAN :
------------------------------------------------------------------------
0/14/7/14 0/15/7/15 0/15/7/1572 0/17/7/1772
------------------------------------------------------------------------
Total: 4
Note: for GPON Frame ID/Slot ID/Port ID/Gemport ID
others Frame ID/Slot ID/Port ID/Service-Port ID
System Response
- The system displays the queried result when the command runs successfully.
- The following table describes the parameter in response to the
command.
Parameter Description 100 Indicates the multicast VLAN index of the port. 0/14/7/14 Indicates the multicast user index.- For GPON access user: Indicates the Frame ID/Slot ID/Port ID/Gemport ID of the multicast user.
- For other access user: Indicates the Frame ID/Slot ID/Port ID/service port ID of the multicast user.
