What switch device has, managed or unmanaged.

Switch type

A network switch is a computer networking device that links networking segments. A switch has different layers, such as layer 2 (a network bridge, operating at the data link layer, interconnecting a small number of devices) and layer 4 (can act as a firewall, amongst other things).

This terminates the end of an optical fiber, and enables quicker connection and disconnection than splicing. The connectors mechanically couple and align the cores of fibers so light can pass. Better connectors lose very little light due to reflection or misalignment of the fibers. In all there have been about 100 types of optic fiber connectors produced.

Switching capacity

The number of packets the device can process and send per second, measured in millions of packets per second (e.g., 148.8 Mpps).

Forwarding rate

The MAC address is the 'Media Access Control Address'. It is a unique address given to a network interface controller (NIC) in a device. A MAC address table shows the addresses in a table format.

MAC address table

Indicates whether the device supports Ethernet frames with a payload larger than the standard 1500 bytes to increase data transfer efficiency.
