DES-3550 Fast Ethernet Layer 2 Switch
Parameter Description
State <Enabled>
Toggle the State field to either enable or disable a given port or group of ports.
Speed/Duplex <Auto>
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 100 Mbps
devices, in full- or half-duplex. The Auto setting allows the port to automatically
determine the fastest settings the device the port is connected to can handle, and
then to use those settings. The other options are Auto, 10M/Half, 10M/Full,
100M/Half and 100M/Full. There is no automatic adjustment of port settings with
any option other than Auto.
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.
Learn
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 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 Disabled.
