TL-SL21098+1G Gigabit Ethernet Smart Switch User Guide

Chapter 2: Introduction of the Product

This part simply describes the features of the model of TL-SL2109 Gigabit Smart Switch, and some information in context about the technology of Switch.

2.1 Port-Trunking function

Basically, TRUNK permits to provide a wider bandwidth between the switches by two or more than two ports (less than four ports generally) working side by side. It means that the TRUNK solves many physical ports as one logical port. When there is no TRUNK, the maximal bandwidth is decided by Auto-negotiation. The good of the TRUNK is that you can use many lower speed devices as a higher speed device. Using the TRUNK, you can only add the adapters in the server machine connected to the switch to solve the traffic between the switch and the server. You also can use the switch to solve the traffic between the switch and the server. You also can use the TRUNK between the switchs to solve the traffic.

TL-SL2109’s TRUNK function supports one TRUNK, which is made up of the seventh and the eighth port, the TRUNK port’s bandwidth can get to 400Mbps.

2.2 Virtual Local Area Network

The Virtual Local Area Network can be out of the constraints of the physical connections. You can move the workstations among the workgroup and the subnet without changing the physical connection. The work stations build up the logical workgroup or the virtual subnet to improve the performance of the system. Poise the flux in the network and utilize the source of the device reasonedly. In the same time, the VLAN decompresses the management and maintenance of the network.

Virtual Group: The members of the groups’ communication with each other will be greatly improved. And not required the router in the system.

Safety: Because only the legal user can forward the information, the safety of the network will be improved.

Economize cost: You can use VLAN in the network without adding the router or re-distributing the cable.

Port-based VLAN is the usual technology of the TL-SL2109. The TL-SL2109P supplies nine Port-based VLAN.

2.3 Priority

The TL-SL2109 supplies the port-based priority. The Switch had two levels, low and high. The switch forwards the frames based on the level of the priority. The frames with high level priority can be solved firstly.
