GPON Access Port Management(port fec)

port fec(gpon)

Function

This command is used to enable or disable the forward error correction (FEC) function of a GPON port. To enhance the data transmission reliability of the downstream link between an OLT and an ONT, run this command. After the FEC function is enabled, the system inserts the redundancy data into the normal packets. In this manner, the line is provided with error tolerance function, but certain bandwidth is wasted. Therefore, use this command when the bandwidth resources are sufficient.

NOTICE:

If a GPON port has a lot of online ONTs, it is recommended that the FEC function not be configured on the GPON port. This is because the configuration of the FEC function may cause some ONTs to go offline.

Format

port portid fec switch

Parameters

Parameter	Description	Value
portid	Indicates the ID of the GPON port whose FEC function is to be configured.	Please see Differences Between Shelves.
switch	Indicates the FEC function of a GPON port. enable: Enables the FEC function of a GPON port. disable: Disables the FEC function of a GPON port. For an XG-PON board, the FEC function cannot be configured manually.	Enumerated type. Options: enable and disable. Default value: GPON board: disable. XG-PON board: enable.

Modes

GPON mode, MA5683T, GPBD

Level

Operator level

Usage Guidelines

• Run the config command to enter global config mode, and then run the interface gpon command to enter GPON mode.
• Currently, the system supports only the FEC function in the downstream function.

Example

To enable the FEC function of GPON port 0/3/0 to enhance the data transmission reliability of the downstream link between an OLT and an ONT, do as follows:

huawei(config-if-gpon-0/3)#port                                                 
{ optical-alarm-profile<K>|portid<U><0,7> }:0
{ fec<K>|laser-switch<K>|ont-auto-find<K>|ont-password-renew<K>|range<K> }:fec  
{ switch<E><enable,disable> }:enable                                            
                                                                                
  Command:                                                                      
          port 0 fec enable

To disable the FEC function of GPON port 0/3/0, do as follows:

huawei(config-if-gpon-0/3)#port                                                 
{ optical-alarm-profile<K>|portid<U><0,7> }:0
{ fec<K>|laser-switch<K>|ont-auto-find<K>|ont-password-renew<K>|range<K> }:fec  
{ switch<E><enable,disable> }:disable                                           
                                                                                
  Command:                                                                      
          port 0 fec disable

System Response

• The system does not display any message after the FEC function of a GPON port is enabled or disabled successfully.
