In practice, the network extension (cascading levels & overall diam eter) must follow the constraint of the IEEE 802.3/802[...]

13 Case1: All switch ports are in the same local area network. Every port can acce ss each other (See Fig. 2-3). If VLAN is enabled and configured, each node in the network that can communicate each other di rectly is bounded in the same VLAN area. Here VLAN area is defin ed by what VLAN you are using. Th e switch support s both port-based VLAN and[...]

20 With the classful addressi ng, it divides IP address int o three classes, class A, class B and class C. The rest of IP addres se s are for multicast and broadcast. The bit length of the network prefix is the sa me as that of the subnet mask an d is denoted as IP address/X, for example, 192. 168.1.0/24. Each class has it s address range described[...]

21 Class D and E: Class D is a cla ss with first 4 MSB (Most significance bit) set to 1-1-1-0 and is used for IP Multicast. See also RF C 1 1 12. Class E is a class with first 4 MSB set to 1-1-1-1 and is used for IP broadcast. According to IANA (Internet Assigned Numbers Authority), there are three specific IP a ddress blocks reserved a nd able to [...]

22 In this diagram, you can see the subnet mask with 2 5-bit long, 255.255.255.128, cont ains 126 members in the su b-netted network. Another is that the length of network prefi x equals the number of the bit with 1 s in that subnet mask. With this, you can easily count the number of IP addresses matched. The following table shows t he re sult. Pre[...]

23 For different network applications, the subnet mask may look like 255.255.255.240. This means it is a small network accommodating a maximum of 15 nodes in the network. Default gateway: For the routed p acket, if the destination is not in the routing t able, all the traffic is put into the device with the design ated IP address, know n as default[...]
