TL-SF2109P/TL-SF2117P/TL-SL2226P Ethernet Smart Switch User Guide
Chapter 1: Introduction of the Product
This chapter simply describes the features of the model of the TL-SF2109/TL-SF2117P
/TL-SL2226P smart Switch and back-knowledge of Fast Ethernet Switch.
1.1 Virtual Local Area Network (VLAN)
Virtual Local Area Network breaks down the constraint of environment, you can move the
workstation freely in the group without change the connection. The technology improves
the performance or subnet of the system, equalizes data flow in the net, utilizes the
resource reasonably, the work of management and maintenance.
Virtual group: The communication will be improved among the group. And there needs
no routers in the group when transferring data to other groups.
Safety: Only the legal users can forward data in the VLAN. So the safety of the net
improves.
Low cost: You can move the workstations freely in the VLAN, and there need no routers
and replacing the cable.
1.2 Port TRUNK
Generally, TRUNK means that two switches can be connected two or more than two (but
less than five) ports side-by-side to supply more band width and more throughput and
self-resume technic. This is to say, TRUNK is to treat several physical connections as
one logic connection. TRUNK is very useful to several lower speed device to a high
speed device.
The current device can simply add more NIC connecting to the server to resolve the
traffic between the switches and the servers.
1.3 AUTO MDI/MDIX
The switch supports MDI/MDIX function, every port of the Switch can be used as normal
port and uplink port. It becomes easy to use, plug and play, when connecting to the other
switches and hubs, whether the direct cable and the crossover cable or not.
The switch, a smart auto-negotiated Ethernet switch, supplies the method of promotion
of the workstation resource.
