In
State
column, the selected port can be enabled or disabled. Once the port disabled, the
port linkage is down and stop to forward any traffic. The default setting is Enable which
means all the ports are functional when you receive the device.
In
Speed/Duplex
column, the port speed and duplex mode can be configured, including
the following selections :
Fast Ethernet Port 1~16 (fa1~fa16): AutoNegotiation, 10M Full Duplex(10 Full), 10M Half
Duplex(10 Half), 100M Full Duplex(100 Full) and 100M Half Duplex(100 Half).
Gigabit Ethernet Combo Port 17~20 (gi17~gi20): AutoNegotiation, 10M Full Duplex(10 Full),
10M Half Duplex(10 Half), 100M Full Duplex(100 Full), 100M Half Duplex(100 Half), 1000M
Full Duplex(1000 Full), 1000M Half Duplex(1000 Half).
The default is Auto Negotiation mode.
Note: Gigabit Ethernet Combo ports port (SFP 17, 18, 19 and 20) in JetNet 5420G
support 100M and 1000M Full mode. When SFP plugged in, Speed/Duplex will be
fixed in Auto Negotiation mode, and the speed is determined by SFP module.
In
Flow Control
column, in order to enable flow control,
“Symmetric”
must be both
applied on local and remote devices, coorespondingly. If
“Disable”
on either one end, it
cannot be assured that the flow control can work perfectly. It is recommended to enable
flow control under Auto Negotiation mode. When using SFP, same speed models are
suggested to utilized on both end devices.
In
Description
column, you can add description to indicate the port location, connected
device or other information. This is a friendly design especially in remote management of
the device.
Once you finish the configuration, click on
Apply
to save the configuration.
Technical Tips: If both ends are not at the same speed, they can’t link with each
other. If both ends are not in the same duplex mode, they will be connected by half
mode.

Port Status
Port Status exposes the current port status after negotiations.
Figure 4.3.3.1 shows you the port status of the Fast Ethernet Ports. The blank area (port
1-8) means the module 1 are not inserted and the Figure 4.3.3.2 is for DDM SFP port
status.
