The following table explains these parameters.
Table 6-3 Ethernet Status
PARAMETER DESCRIPTION
Ethernet Port 1-4
Link Status This shows the current status of the LAN which can be
Up
or
Down
.
Duplex This shows the duplex mode of the Ethernet connections (either
Full
for full duplex
or
Half
for half duplex).
Speed This shows the speed of the Ethernet connections (either
10M
for 10Mbps or
100M
for 100Mbps).
Flow Control This shows if flow control is enabled on this port or not.
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 Prestige uses IEEE802.3x flow control in full duplex mode and backpressure
flow control in half duplex mode.
IEEE802.3x 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.
