Device model: NE40E-X8
Software version: V600R009C20SPC600
Symptom: An IPoE terminal is slow in obtaining IP addresses, taking over 20 minutes.
The dhcp-broadcast configuration on the BAS
interface allows the device to send DHCP unicast packets as broadcast packets.
In addition, all the uplink interfaces on the OLT are configured with a broadcast suppression level of 3, allowing packets to be transmitted at a minimum rate of 24kbps and a maximum rate of 48 pps. The downstream broadcast packets on the NE40 are discarded frequently.
