Port Description

The DXS-3326GSR supports a port description feature where the user may name various ports on the Switch. To assign
names to various ports, click the Port Description on the Configuration menu:
DXS-3326GSR Gigabit Layer 3 Switch
those settings. The other options are Auto, 10M/Half, 10M/Full, 100M/Half,
100M/Full, 1000M/Full_M, and 1000M/Full_S. There is no automatic adjustment
of port settings with any option other than Auto. The master and slave parameters
refer to connections running a 1000BASE-T cable for connection between the
Switch port and other device capable of a gigabit connection. The master setting
will allow the port to advertise capabilities related to duplex, speed and physical
layer type. The master setting will also determine the master and slave
relationship between the two connected physical layers. This relationship is
necessary for establishing the timing control between the two physical layers. The
timing control is set on a master physical layer by a local source. The slave
setting uses loop timing, where the timing comes form a data stream received
from the master. If one connection is set for 1000M/Full_M, the other side of the
connection must be set for 1000M/Full_S. Any other configuration will result in a
link down status for both ports
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.
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 and Filtering for information on entering MAC
addresses into the forwarding table. The default setting is Disabled.
