GS-3012/GS-3012F User’s Guide H A P T E R Spanning Tree Protocol This chapter introduces the Spanning Tree Protocol (STP). 10.1 Introduction to Spanning Tree Protocol (STP) STP detects and breaks network loops and provides backup links between switches, bridges or routers.
Page 85: How Stp Works
GS-3012/GS-3012F User’s Guide 10.1.2 How STP Works After a bridge determines the lowest cost-spanning tree with STP, it enables the root port and the ports that are the designated ports for connected LANs, and disables all other ports that participate in STP. Network packets are therefore only forwarded between enabled ports, eliminating any possible network loops.

ES-2024A User’s Guide P P E N D I X IP Subnetting IP Addressing Routers “route” based on the network number. The router that delivers the data packet to the correct destination host uses the host ID. IP Classes An IP address is made up of four octets (eight bits), written in dotted decimal notation, for example, 192.168.1.1.
Page 237: Table 85 Allowed Ip Address Range By Class
ES-2024A User’s Guide Since the first octet of a class “A” IP address must contain a “0”, the first octet of a class “A” address can have a value of 0 to 127. Similarly the first octet of a class “B” must begin with “10”, therefore the first octet of a class “B”...
Page 238: Table 87 Alternative Subnet Mask Notation
ES-2024A User’s Guide Since the mask is always a continuous number of ones beginning from the left, followed by a continuous number of zeros for the remainder of the 32 bit mask, you can simply specify the number of ones instead of writing the value of each octet. This is usually specified by writing a “/”...
Page 239: Table 89 Subnet 1
ES-2024A User’s Guide Note: In the following charts, shaded/bolded last octet bit values indicate host ID bits “borrowed” to form network ID bits. The number of “borrowed” host ID bits determines the number of subnets you can have. The remaining number of host ID bits (after “borrowing”) determines the number of hosts you can have on each subnet.
Page 240: Table 91 Subnet 1
ES-2024A User’s Guide Example: Four Subnets The above example illustrated using a 25-bit subnet mask to divide a class “C” address space into two subnets. Similarly to divide a class “C” address into four subnets, you need to “borrow” two host ID bits to give four possible combinations of 00, 01, 10 and 11. The subnet mask is 26 bits (11111111.11111111.11111111.11000000) or 255.255.255.192.

Page 242: Table 97 Class B Subnet Planning
ES-2024A User’s Guide Subnetting With Class A and Class B Networks. For class “A” and class “B” addresses the subnet mask also determines which bits are part of the network number and which are part of the host ID. A class “B” address has two host ID octets available for subnetting and a class “A” address has three host ID octets (see Table 84 on page 236) available for subnetting.
