Flow Control Enables or disables the receipt or
transmission of PAUSE frames.
PAUSE frames allow the network
adapter and a switch to control the
transmit rate. The side that is
receiving the PAUSE frame
momentarily stops transmitting. By
enabling TOE, network
performance improves, but with
the increased performance, TOE
performance is more susceptible
to packet loss when flow control is
disabled. Enable flow control to
reduce the number of packets lost.
1. In Microsoft Windows, right-
click the Network Adapter in
Network Connections and then
click Properties.
2. Click the Configure button and
then the Advanced tab.
3. Set the desired Flow Control
value.
Interrupt
Moderation
Enables interrupt moderation,
which limits the rate of interrupt to
the CPU during packet
transmission and packet

packet transmission and packet
reception. Enable is the default
