The following parameters can be configured:
Parameter Description
Unit
Choose the switch in the switch stack for which to configure these settings..
From/To
Choose the port or sequential range of ports.
State
Toggle the State field to either enable or disable a given port or group of ports.
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.
Speed/Duplex
Toggle the Speed/Duplex field to either select the speed and duplex/half-duplex state of the
port. Auto denotes auto-negotiation between 10 and 1000 Mbps devices, in full- or half-duplex.
