By default, the
discovery-frequency value is
50, the discovery-length value
is 41500 TQ, and the
cycle-length value is 65535 TQ.

Required
By default, the minimum
bandwidth of an ONU is 2048
kbps, the maximum bandwidth is
23552 kbps, and low delay is
adopted.

Optional
By default, ONU Report
messages support two queue
sets. The default thresholds of
queue 4 and queue 5 are 65535,
while the default thresholds of
other queues are 0.
1 time quantum (TQ) is equal to 16 ns, which is the time it takes to transmit two bytes of data at 1
Gbps.
You can manually load an external DBA algorithm file by using the dba-algorithm update
command as needed.
DBA-related configuration is only recommended for administrators. Improper DBA configuration
may terminate all the services.
H3C ONU Report frames support up to two queue sets.
The sum of the minimum uplink bandwidths configured for all created ONU ports under an OLT
port cannot exceeds 921600 kbps, namely, 900 Mbps.
