Speed/Duplex
Select the speed and the duplex mode of the Ethernet connection on this port.
Choices are
Auto
,
10M/Half Duplex
,
10M/Full Duplex
,
100M/Half Duplex
,
100M/
Full Duplex
and
1000M/Full Duplex
(for Gigabit ports only).
Selecting
Auto
(auto-negotiation) allows one port to negotiate with a peer port
automatically to obtain the connection speed and duplex mode that both ends
support. When auto-negotiation is turned on, a port on the ONU negotiates with the
peer automatically to determine the connection speed and duplex mode. If the peer
port does not support auto-negotiation or turns off this feature, the ONU determines
the connection speed by detecting the signal on the cable and using half duplex
mode. When the ONU’s auto-negotiation is turned off, a port uses the pre-configured
speed and duplex mode when making a connection, thus requiring you to make sure
that the settings of the peer port are the same in order to connect.
Flow Control
A concentration of traffic on a port decreases port bandwidth and overflows buffer
memory causing packet discards and frame losses.
Flow Control
is used to regulate
transmission of signals to match the bandwidth of the receiving port.
The ONU uses IEEE 802.3x flow control in full duplex mode and backpressure flow
control in half duplex mode.
IEEE 802.3x flow control is used in full duplex mode to send a pause signal to the
sending port, causing it to temporarily stop sending signals when the receiving port
memory buffers fill.
Back Pressure flow control is typically used in half duplex mode to send a "collision"
signal to the sending port (mimicking a state of packet collision) causing the sending
port to temporarily stop sending signals and resend later. Select
Flow Control
to
enable it.
802.1p Priority
This priority value is added to incoming frames without a (802.1p) priority queue tag.
See
Priority Queue Assignment
in
for more information.

to save your changes to the ONU’s run-time memory. The ONU loses
these changes if it is turned off or loses power, so use the
