Getting Started
Getting Started with SEGGER embOS/IP Switch Board
The embOS/IP Switch Board is intended to be mainly a demonstrator board for the Tail Tagging add-on of SEGGER's embedded IP stack emNet. Micrel/Microchip has developed switches which can expand one physical port into 1+n ports, supported by the so-called Tail Tagging mode. This enhancement allows to establish multiple physical external ports when only one physical Ethernet port is available on the CPU - by choosing another PHY.
The embOS/IP Switch Board provides a solid starting point for a project that requires multiple physical Ethernet ports by using SEGGER’s middleware products.
