4.2.14 System Admin->Ports->Port Status and Configuration Configure the characteristics related to link operations. All of the parameters on the Port Status and
Configuration page are toggle settings. To change, or toggle, between options, hit Ctrl-M to move
the curser to the ports field and strike the space bar when the appropriate option is highlighted. To
modify ports 17 to 26, tab through ports 1 to 16. The comments field is available to enter a description
of the port.
Type
The type of port, this field is not user configurable.
Admin field
Enables or Disables the port.
Link
The status of a port, it is Up when a port is connected and active.
Mode
Offers the choice of Full-duplex, Half-duplex, or Auto negotiation as well as speed selection
among 10Mbps, 100Mbps, 1000Mbps or auto negotiation. Enabling auto-negotiation on a port
allows a port to sense the communication speed and negotiate the duplex mode (full duplex or
half duplex) automatically. The ports select the highest possible throughput. The port can auto-
negotiate with any port that is compliant with IEEE 802.3u. If the other port is not IEEE802.3u
compliant, the port defaults to half-duplex, 10 Mbps mode. Users can operate the
communication speed and duplex mode manually.
Flow Control
Enables or disables Flow Control. Flow control is a protocol preventing packets from being
dropped by reducing the amount of traffic to a level that can be accommodated. If enabled
on both ends of a connection, it prevents the sender from sending data until the receiver can
accept it. The switch complies with the IEEE802.3x flow control standard.
Gigabit Ports
For the two-gigabit ports on each switch, the port type can be chosen. The default is the port
using the RJ-45 interface. Select the GBIC interface by plugging a GBIC connector. The GBIC
interface has higher priority than the shared RJ-45 interface.
