Gigabit Uplink Web Smart Switch

¾¾ HD: half-duplex, the port supports transmission between the device and the client in only one direction at a time.

¾¾ FD: full-duplex, the port supports transmission between the device and its link partner in both directions simultaneously.

Auto negotiation is a protocol between two link partners that enables a port to advertise its transmission rate and duplex mode to its partner.

55555555 Flow Control

Flow control enables lower speed devices to communicate with higher speed devices. This is implemented by the higher speed device refraining from sending packets.

55555555 Port Security

If the port security is enabled, it will not learn new MAC address and only transmit the frames from the MAC address list in the port’s static MAC address table.

555555 Port Statistic and Port Status

Port Statistic calculates the statistics of each port, such as how many frames, error frames, broadcast frames it has received and so on.

Port Status indicates whether the port is linked, not linked or disabled, what speed and duplex mode it is working on, and whether flow control is enabled or disabled.

555555 Storm Control

Storm control limits the amount of multicast, broadcast and UL (the address hasn't been learned\ frames accepted and forwarded by the device. When Layer 2 frames are forwarded, broadcast, multicast and UL frames are flooded to all ports on the relevant VLAN. This occupies bandwidth, and loads all nodes on all ports.

A Storm is a result of an excessive amount of these frames simultaneously transmitted across a network by a single port. Forwarded message responses are heaped onto the network, straining network resources or causing the network to time out. Storm control is enabled for all ports by defining the packet type and the rate at which the packets are transmitted. The system measures the incoming defined frame rates on each port, and discards the frames when the rate exceeds a user-defined rate.
