Page 23: Getting To Know Your Switch
Switch. 1.1 Introduction The GS2200-48 is a stand-alone layer 2 Gigabit Ethernet (GbE) switch. It comes with 44 100/1000 Mbps Ethernet ports, 4 Dual Personality interfaces (each consisting of one RJ-45 Gigabit port and one slot for a mini-GBIC transceiver (SFP module) with one port active at a time) and two mini-GBIC transceivers for fiber- optic uplink connections.
Page 24: High Performance Switching Example
Trunking can be used with copper cabling over relatively shorter distances than fiber-optic connections. Figure 2 High Performance Switching 1 Gbps Trunk Branch GS2200-48 User’s Guide...
Page 25: Gigabit Ethernet To The Desktop
Ports in the same VLAN group share the same frame broadcast domain, thus increasing network performance by reducing broadcast traffic. VLAN groups can be modified at any time by adding, moving or changing ports without any re- cabling. GS2200-48 User’s Guide...

• Change the password. Use a password that’s not easy to guess and that consists of different types of characters, such as numbers and letters. • Write down the password and put it in a safe place. GS2200-48 User’s Guide...
Page 27 If you forget your password, you will have to reset the Switch to its factory default settings. If you backed up an earlier configuration file, you would not have to totally re-configure the Switch. You could simply restore your last configuration. GS2200-48 User’s Guide...

Page 330 (“double-tagged” frames), the service provider can manage up to 4,094 VLAN groups with each group containing up to 4,094 customer VLANs. This allows a service provider to provide different service, based on specific VLANs, for many different customers. GS2200-48 User’s Guide...
Page 331 RIP (Routing Information Protocol) allows a routing device to exchange routing information with other routers. VRRP Virtual Router Redundancy Protocol (VRRP), defined in RFC 2338, allows you to create redundant backup gateways to ensure that the default gateway of a host is always available.

192.168.1.1). Each of these four parts is known as an octet. An octet is an eight-digit binary number (for example 11000000, which is 192 in decimal notation). Therefore, each octet has a possible range of 00000000 to 11111111 in binary, or 0 to 255 in decimal. GS2200-48 User’s Guide...

Page 342 In this example, the company network address is 192.168.1.0. The first three octets of the address (192.168.1) are the network number, and the remaining octet is the host ID, allowing a maximum of 2 – 2 or 254 possible hosts. GS2200-48 User’s Guide...
Page 343 You can “borrow” one of the host ID bits to divide the network 192.168.1.0 into two separate sub-networks. The subnet mask is now 25 bits (255.255.255.128 or /25). The “borrowed” host ID bit can have a value of either 0 or 1, allowing two subnets; 192.168.1.0 /25 and 192.168.1.128 /25. GS2200-48 User’s Guide...
Page 344 Similarly, to divide a 24-bit address into four subnets, you need to “borrow” two host ID bits to give four possible combinations (00, 01, 10 and 11). The subnet mask is 26 bits (11111111.11111111.11111111.11000000) or 255.255.255.192. GS2200-48 User’s Guide...

Page 347: Configuring Ip Addresses
The subnet mask specifies the network number portion of an IP address. Your Switch will compute the subnet mask automatically based on the IP address that you entered. You don't need to change the subnet mask computed by the Switch unless you are instructed to do otherwise. GS2200-48 User’s Guide...
Page 348 Regardless of your particular situation, do not create an arbitrary IP address; always follow the guidelines above. For more information on address assignment, please refer to RFC 1597, Address Allocation for Private Internets and RFC 1466, Guidelines for Management of IP Address Space. GS2200-48 User’s Guide...
