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
switch 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.

This page is used to enable or disable the LACP function.
Available settings are explained as follows:
Item Description
LACP Enable – Click it to enable such function.
Disable – Click it to disable the function.
System Priority The priority is used to determine which switch (local or
remote) on the LAG connection is able to decide LACP
activities. The lower the number is, the higher the priority for
Vigorwitch will be. Therefore, the switch with the highest
system priority (e.g., 1) can make decisions about which ports
actively participate in LAG at a given time.
