MDI/MDIX:
A medium dependent interface (MDI) port is an Ethernet port connection typically used on the Network
Interface Card (NIC) or Integrated NIC port on a PC. Switches and hubs usually use Medium dependent
interface crossover (MDIX) interface. When connecting the Switch to end stations, user have to use
straight through Ethernet cables to make sure the Tx/Rx pairs match up properly. When connecting the
Switch to other networking devices, a crossover cable must be used.
This switch provides a configurable MDI/MDIX function for users. The switches can be set as an MDI port in
order to connect to other hubs or switches without an Ethernet crossover cable.
Auto MDI/MDIX is designed on the switch to detect if the connection is backwards, and automatically
chooses MDI or MDIX to properly match the connection. The default setting is "Auto" MDI/MDIX.
Flow Control: You can enable this function to mitigate the traffic congestion. Ports configured for full-duplex
use 802.3x flow control, half-duplex ports use backpressure flow control. The default setting is Disabled.
Link Status: Reporting Down indicates the port is disconnected.
System > SNMP Settings
Simple Network Management Protocol (SNMP) is an OSI Layer 7 (Application Layer) protocol designed
specifically for managing and monitoring network devices. SNMP enables network management stations to
read and modify the settings of gateways, routers, switches, and other network devices. Use SNMP to
configure system features for proper operation, monitor performance and detect potential problems in the
Switch or LAN.
Managed devices that support SNMP include software (referred to as an agent), which runs locally on the
device. A defined set of variables (managed objects) is maintained by the SNMP agent and used to manage
the device. These objects are defined in a Management Information Base (MIB), which provides a standard
presentation of the information controlled by the on-board SNMP agent. SNMP defines both the format of the
MIB specifications and the protocol used to access this information over the network.
The default SNMP setting is disabled. Click Enabled to set Community Settings and then Apply.

Community Setting: In support of SNMP version 1, the Web-Smart Switch accomplishes user
authentication by using Community Settings that function as passwords. The remote user SNMP application
and the Switch SNMP must use the same community string. SNMP packets from a station that are not
authenticated are ignored (dropped).
