Flow Control
Displays the flow control scheme used for the various port configurations. Ports configured for full-
duplex use 802.3x flow control, half-duplex ports use backpressure flow control, and Auto ports use
an automatic selection of the two. The default is Disabled.
Learning
Enable or disable MAC address learning for the selected ports. When Enabled, destination and
source MAC addresses are automatically listed in the forwarding table. When learning is Disabled,
MAC addresses must be manually entered into the forwarding table. This is sometimes done for
security or efficiency. See the section on Forwarding/Filtering for information on entering MAC
addresses into the forwarding table. The default setting is Disabled.
Click Apply to implement the new settings on the Switch.
At the bottom of the Port Configuration window is a Show Err-disabled ports
link to display the information about ports that have
had their connection status disabled, for reasons such as loopback detection or link down status. Clicking this link will display the
following window:
