Here is how to enable it on R1. PAS unit 0, subunit 0, f/w version 2-55, rev ID 0x2800001, version 2 idb = 0x6080D54C, ds = 0x6080F304, ssb=0x6080F4F4 Fragment-free switching is a modified variety of cut-through switching. The first 64 bytes of a frame are examined for any errors, and if none are detected, it will pass it on. The reasoning behind this method is that any errors are most likely to be found in the first 64 bytes of a frame. Something needed to change and change came in the form of a new addressing standard for IP. Learning from mistakes made and responding to changes in business requirements, the Internet Engineering Task Force (IETF) published the first of many IPv6 standards as far back as 1998. Same drill as before. You know this is a Class C address, and that to get from 24 to 25 bits, you need to steal 1 bit. Tick one across in the top row and then one down in the left column: If the receiving system is being sent more information than it can process, it will ask the sending system to stop for a short time. This normally happens when one side uses broadband and the other uses a dial-up modem. The packet sent telling the other device to stop is known as a source quench message. Come exam day, or when troubleshooting a subnetting issue on a live network, you will want to get to your answer quickly and accurately. For these reasons, I devised an easy way to subnet, which is the subject of my Subnetting Secrets Amazon Kindle book. You won’t need to read it though to be honest, because I cover what you need to know in this book. command. The native VLAN of each port on the trunk must match. This command is part of the CCNA syllabus and is considered a security measure. Switch1#show vlan The next 4 bits in the Multicast address represent the scope. In IPv6 Multicasting, this field is a mandatory field that restricts Multicast packets from being sent to other areas in the network. This field essentially provides the same function as the TTL field that is used in IPv4. However, with IPv6, there are several types of scopes, which are listed in Table 3.7 below: Vlan Mac Address Type Ports 5.Convert 32 to binary and hex Binary = 100000 Any delay in passing traffic is known as latency. Cisco switches offer three ways to switch the traffic, depending upon how thoroughly you want the frame to be checked before it is passed on. The more checking performed, the more latency you will introduce to the switch. The three switching modes to choose from are: Therefore, your mask will be 255.255.255.128, and your subnets will go up in increments of 128. You can’t actually steal less than 1 bit for a Class C address; this will give you only two subnets: Address classes Using IP addresses Subnetting Store-and-forward Connect network devices such as printers and PCs Give access to network servers and routers Segment the network with VLANs 16 x 16 = 256 The Subnetting Secrets Chart Binary = 10110101 You will connect to a new switch via the console port, the same as with any new router, because in order to connect via Telnet or SSH (more on these later), you will need to have at least a line or two of configuration on the switch already. Many of the initial configuration commands for the switch are the same for an initial router configuration. Switch2(config)vlan 5 Switch2(config-vlan)#name RnD There are two common ways to associate ports with VLANs – statically or dynamically. You should also verify the IP addressing scheme. If you are statically All devices on a network need some way to identify themselves as a specific host. Early networks simply used a naming format, and a server on the network kept a map of MAC addresses to host names. Tables quickly grew very large and with this grew issues such as consistency and accuracy (see Figure 2.5 below). IP addressing effectively resolved this issue. The process of switching modes can best be described by using a metaphor. You are the bouncer at a nightclub and are asked to make sure that everyone who enters has a picture ID – you are not asked to make sure the picture matches the person, only that the ID has a picture. With this method of checking, people are surely going to move quickly to enter the establishment. This is how cut-through switching works.
