Configuring the Working Mode of a PON Interface
Context
When the router is connected to an EPON interface of an OLT, configure the router to automatically determine the working mode according to the received optical signal, or configure the PON interface connected to the OLT to work in EPON mode.
You are advised to configure a PON interface to work in auto-negotiation mode. To trigger another negotiation after a successful negotiation, reset the PON board. For example, if a PON interface of the router has automatically negotiated to work in EPON mode, you need to reset the PON board so that this interface can automatically negotiate to work in GPON mode when this interface connects to an OLT's PON interface that works in GPON mode.
If a PON interface is transmitting service data, changing the working mode will interrupt services on the PON interface. Perform this operation with caution.
Procedure
- Run system-view
The system view is displayed.
- Run interface pon interface-number
The PON interface view is displayed.
- Run port mode epon
The PON interface is configured to work in EPON mode.
By default, a PON interface automatically determines the working mode according to the received optical signal.
- (Optional) Run epon compatibility dba
The compatibility mode of the EPON interface is configured.
By default, the compatibility mode of an EPON interface is not configured.
After running the epon compatibility dba command on a device, restart the device to make the configuration take effect.
If the device connects to an optical line terminal (OLT) through an EPON interface and the remote OLT sends non-standard DBA packets, the physical status of the EPON interface on the device is Down. You can perform this step so that the device can process non-standard DBA packets from the remote OLT and transmit services.
