description
The ThunderSWITCH TNETX3100 is a 10-port 10-/100-Mbit/s Ethernet switch. A low-cost solution is achieved
by combining the TNETX3100 with physical interfaces and low-cost packet memory. The TNETX3100 provides
32 internal media access controller (MAC) address registers, collision-based flow control, virtual LAN (VLAN)
support, and uplink support.
