port. Below are the selections you can choose:
Fast Ethernet Port 1~24 (fa1~fa24): AutoNegotiation, 10M Full Duplex(10 Full),
10M Half Duplex(10 Half), 100M Full Duplex(100 Full) and 100M Half Duplex(100
Half).
Gigabit Ethernet Port 25~28: (gi25~gi28): 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 mode is Auto Negotiation mode.
In Flow Control column, “Symmetric” means that you need to activate the flow
control function of the remote network device in order to let the flow control of
that corresponding port on the switch to work. “Disable” means that you don’t
need to activate the flow control function of the remote network device, as the
flow control of that corresponding port on the switch will work anyway.
Once you finish configuring the settings, 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.
