port igmp-forward eth(gpon profile)
Function
This command is used to configure the IGMP packet forwarding mode
of the ONT ethernet port in a GPON ONT service profile. In different IGMP packet
forwarding modes, the upstream IGMP packet from the ONT to network-side are
different.
- When the user-side packets are strictly planned, the IGMP pakcket forwarding
mode of the ONT is different selected.
- If the ONT is directly connected to the home gateway, select the translation mode.
- If the ONT is directly connected to the set-top box (STB) or PC, select the default mode.
- When the packets for the such services as games are unknown IGMP packets and need to be transparently transmitted to the upper-layer device for processing, select transparent.
- When the ONT does not support the set of IGMP packet forwarding mode or the OLT does not specify the ONT IGMP pakcets forwarding mode, select the unconcern mode.
Format
port igmp-forward eth ont-portlist {{{
translation |
default } vlanid
[ priority ] } |
transparent }
undo port igmp-forward eth ont-portlist
undo port igmp-forward eth ont-portlist
Parameters
| Parameter | Description | Value |
|---|---|---|
| ont-portlist | Indicates all the ports on which the priority and forwarding mode of IGMP packets are to be set. This parameter supports comma (,) and en dash (-). For example, ont-portlist of 0, 2-3 indicates ONTs 0, 1, 2,3. | Character string type, a string of 1-128 characters. |
| translation |
Sets the forwarding mode of IGMP packets to translation.
Only switching mode 1:1 is supported. In network application, the VLAN tags carried by user-side packets are different and the VLANs need to be planned on the optical line terminal (OLT). In translation mode, the ONT switches the VLAN tags of user-side packets to new VLAN tags and then forwards the packets to the OLT. If the VLAN tags carried by user-side packets have been planned, the ONT does not need to translate the VLAN tags of IGMP packets by translation parameter again. |
- |
| default | Sets the forwarding mode of the IGMP packets to default tag, the ONT adds a new VLAN tag to the user-side packets and then forwards the packets upstream to the OLT. | - |
| vlanid |
Sets the VLAN used in the translation or
default mode after this command is executed.
|
Numeral type. Range: 0-4095. |
| priority | You can determine whether to specify the priority of the IGMP packets according to requirements after the forwarding mode is set to translation or default. If you do not specify this parameter, user packets are transmitted upstream to the OLT using the original priority. The priority increases with the value. | Numeral type. Range: 0-7. |
| transparent | Sets the forwarding mode of the IGMP packets to transparent. The ONT does not process VLAN tags of all user-sides packets including broadcast packets and multicast packets but only forwards these packets upstream to the other side. | - |
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.
- You can run the display ont-srvprofile gpon command to query the forwarding mode of the IGMP packets on the Ethernet port of ONT in the GPON ONT service profile.
- This command conflicts with the igmp-forward(gpon profile) command for configuring the ONT-based VLAN switching function.
Example
To set the forwarding mode of IGMP packets on Ethernet ports 1 and 2 to
transparent in GPON ONT service profile 10, do as follows:
huawei(config-gpon-srvprofile-10)#port igmp-forward eth
{ ont-portlist<S><Length 1-128> }:1-2
{ default<K>|translation<K>|transparent<K> }:transparent
Command:
port igmp-forward eth 1-2 transparent
Set ONT port(s) IGMP forward configuration, success: 2, failed: 0
To delete the forwarding mode setting of IGMP packets on Ethernet ports 1 and
2 in ONT service profile 10, do as follows:huawei(config-gpon-srvprofile-10)#undo port igmp-forward eth
{ ont-portlist<S><Length 1-128> }:1-2
Command:
undo port igmp-forward eth 1-2
Delete ONT port(s) IGMP forward configuration, success: 2, failed: 0
System Response
- The system displays the message "Set ONT port(s) IGMP forward configuration, success: x, failed: y" after the forwarding mode of IGMP packets is set successfully. "x" indicates the number of ports on which the forwarding mode is set successfully and "y" indicates the number of ports on which the forwarding mode fails to be set.
