Auto Negotiation:
Only “Enable” and “Disable” two states can be chosen. “Enable” means
the port adopted the auto-negotiation algorithm to exchange the
capability with the linked partner. When enabled, the speed, duplex mode
and flow control mode may change. “Disable” means the forced mode is
adopted. When disabled, if you want to set up a connection successfully,
you must have both port configuration of local port and linked partner be
the same. If their configuration is different, the link will not be set up
successfully. In Signamax 065-1600 series, fiber port supports forced
mode only.
Speed/Duplex:
Set the mode of speed and duplex. In speed, 10/100/1000Mbps baud
rate is available for Fast Ethernet TP port. The Fiber port is available in
speed 1000Mbps only. If the media is 1Gbps fiber, it is always 1000Mbps
and the duplex is full only. If the media is TP, the Speed/Duplex is
comprised of the combination of speed mode, 10/100/1000Mbps, and
duplex mode, full duplex and half duplex.
Flow Control:
There are three modes to choose in flow control, including Asymmetric,
Symmetric and Disable. If Symmetric flow control is set, both parties can
send PAUSE frame to the transmitting device(s) if the receiving port is
too busy to handle. If Asymmetric flow control is set, this will let the
receiving port not care the PAUSE frame from transmitting device(s).
This is one-way flow control. When it is set Disable, there will be no flow
control in the port. It drops the packet if too much to handle.
Default: Symmetric in full-duplex mode and Backpressure in half duplex.
