3.6. NMU Settings
The G.hn (Ethernet) properties of NMU.
3.6.1. Port Setup (G.hn:Port)
To configure NMU Ethernet port properties, include speed, flow control, and maximum Downstream/Upstream
rate (bandwidth control) of port LAN1/LAN2/EoC1.
3.6.2. QoS (G.hn:QoS)
Total 4 prioritized queues are provided for Ethernet packets, denoted as
Queue0
(lowest priority),
Queue1
,
Queue2
and
Queue3
(highest priority). By default, packet priority is based on 802.1p, IPv4 TOS / IPv6 TC or
DSCP. Refer
Chapter 4 Advanced Features page 37
for more EOC 10-01/EoC 10-02 QoS mechanism detail. The
default QoS scheme is based o 802.1p, you may change it to check IP priority (as TOS/TC or DSCP ) instead of
802.1p.
We can further assign packet priority based on TCP/UDP port protocol. For example, as the following setting
diagram we classify packet with TCP/UDP port between ‘20000’ to ‘20050’(in decimal) as the highest priority
packet goes to Queue3; other normal packets go to Queue0.
