Configure Port Settings and Flow Control
You can configure global flow control for all ports and view, configure, and monitor the port
information for individual ports.
From the Switching > Ports menu, you can access pages that are described in the following
sections:
• Configure IEEE 802.3x Global Flow Control on page 86
• Configure the Port Settings on page 87
Configure IEEE 802.3x Global Flow Control
Flow control helps to prevent data loss when the port cannot keep up with the number of
frames being switched. When flow control is enabled, the switch can send a pause frame to
stop traffic on a port if the amount of memory used by the packets on the port exceeds a
preconfigured threshold and responds to pause requests from partner devices.
The paused port does not forward packets for the period of time specified in the pause frame.
When the pause frame time elapses, or the utilization returns to a specified low threshold, the
switch enables the port to again transmit frames.
To configure port settings:
1. Connect your computer to the same network as the switch.
You can use a WiFi or wired connection to connect your computer to the network, or
connect directly to a switch that is off-network using an Ethernet cable.
2. Launch a web browser.
3. In the address field of your web browser, enter the IP address of the switch.
If you do not know the IP address of the switch, see Change the Default IP Address of the
Switch on page 10.
The login window opens.
4. Enter the switch’s password in the Password field.
The default password is password.
The System Information page displays.
5. Select Switching > Ports > Global Configuration.
The Global Configuration page displays.
6. Next to Global Flow Control (IEEE 802.3x) Mode, enable or disable IEEE 802.3x flow control
on the system:
• Enable. The switch sends pause packets if the port buffers become full. That is, flow
control is enabled.
• Disable. The switch does not send pause packets if the port buffers become full. That
is, flow control is disabled. This the default setting.
