Speed: Gigabit Fiber connections can operate in 1000M Full Force Mode, Auto Mode or Disabled. Copper
connections can operate in Forced Mode settings (1000M Full, 100M Full, 100M Half, 10M Full, 10M Half),
Auto, or Disabled. 100M Fiber connections support 100M Full Force Mode, 100M Half Force Mode, or
Disabled. The default setting for all ports is Auto.
NOTE: Be sure to adjust port speed settings
appropriately after changing the connected cable
media types.
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 > SNMP Global State
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
