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 Dis-
abled, MAC addresses must be manually entered into the forwarding table. This is sometimes
done for reasons of security or efficiency. See the section on Forwarding/Filtering for
information on entering MAC addresses into the forwarding table. The default setting is
Enabled.
Medium Type If configuring the Combo ports, this defines the type of transport medium to be used, whether
copper or fiber.
