Configuring QoS in an EPON System
QoS Configuration Task List in an EPON System
QoS configurations in an EPON system are the same as those in Ethernet, and the corresponding
configuration commands in OLT port view and ONU port view are the same as those in Ethernet port
view too. For detailed configuration, refer to the corresponding chapters above.
Table 12-1 and Table 12-2 show how to configure QoS for downlink traffic and uplink traffic in an EPON
system.
