The OLT can query and configure the functions mentioned above. You can use the related query 

commands to query the status of a function on the ONU. You can also configure parameters for a 

function on the OLT, and the OLT will issue the configured parameters to the ONU automatically. The 

query or configuration command is identified by the Ext.Opcode field in the Organization Specific 

OAMPDUs. The codes and configurations to be queried or configured are encapsulated in the payload 

field. For details, refer to 

.  

On an S7900E switch, you need not enable extend OAM manually; instead, extended OAM is enabled 

on a port automatically when you enable Ethernet OAM on the port.  

Extended OAM discovery timeout time refers to the timeout time of extended OAM messages 

exchanged between an OLT and its ONU during an extended OAM discovery process.  

Follow these steps to configure the extended OAM discovery timeout time: 

Enter system view 

— 

Enter FTTH view

If an OLT stays down after being bundled with an ONU port, you can change the extended OAM 

discovery timeout time to a larger value.
