The OLT can configure the following functions for the ONU:
z Basic port configurations, including duplex mode, rate, and traffic control.
z VLAN management and configuration
z Multicast
z QoS
z DBA
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 Organization Specific OAMPDU .
