Manage flow control for a port
IEEE 802.3x flow control works by pausing a port if the port becomes oversubscribed
(that is, the port receives more traffic than it can process) and dropping all traffic for
small bursts of time during the congestion condition.
You can enable or disable flow control for an individual port. By default, flow control is
disabled for all ports.
To manage flow control for a port:
1. Open a web browser from a computer that is connected to the same network as the
switch, or connected directly to the switch through an Ethernet cable.
2. Enter the IP address that is assigned to the switch.
A login window opens.
3. Enter the device management password.
The password is the one that you specified the first time that you logged in. The user
name and password are case-sensitive.
The HOME page displays.
The PORT STATUS pane displays on the right or the bottom of the HOME page,
depending on the size of your browser window.
A port that is in use shows as UP. A port that is not in use shows as AVAILABLE.
4. Select the port.
The pane displays detailed information about the port.
5. Click the EDIT button.
The EDIT PORT page displays for the selected port.
If the QoS mode on the switch is Port-Based (the default setting), the Priority menu
displays on the page. If the QoS mode is 802.1P/DSCP, the Priority menu does not
display.
6. In the Flow Control section, enable or disable flow control by clicking the button.
When flow control is enabled, the button bar displays green.
7. Click the APPLY button.
