CHAPTER 1 Getting to Know Your Switch This chapter introduces the main features and applications of the Switch. 1.1 Introduction The ES-315 and ES-315-F are intelligent layer 2 Ethernet switches. • The ES-315 has four 10/100Mbps LAN ports and one 10/100Mbps WAN port. • The ES-315-F has four 10/100Mbps LAN ports and one Fast Ethernet SFP (Small Formfactor Pluggable) WAN slot. See Chapter 22 on page 131 for a full list of software features available on the Switch. 1.1.1 Overview Use the Switch to connect up to four devices to your network. The following figure shows the Switch (A) connecting several devices (1 ~ 4) and allowing them to communicate with one another and access the Internet through the Internet Service Provider's network switch (B). Figure 1 Internet Access through the Switch 1.1.2 IEEE 802.1Q VLAN Application Example A VLAN (Virtual Local Area Network) allows a physical network to be partitioned into multiple logical networks. Stations on a logical network belong to one group. A station can belong to more than one group. With VLAN, a station cannot directly talk to or hear from stations that are not in the same group(s) unless such traffic first goes through a router. For more information on VLANs, refer to Chapter 7 on page 57. ES-315/ES-315-F User's Guide 23
