Basic Switching Troubleshooting Switch1(config)#int fast 0/2 Switch1(config-if)#duplex ? The OSI model divides all network functions into seven distinct layers. The layered model starts at Layer 7 and goes all the way down to Layer 1. The more complex functions, which are closer to the user, are at the top, moving down to network cable specifications at the bottom layer, as illustrated in Table 1.2 below: Received 956 broadcasts, 0 runts, 0 giants, 0 throttles Day 2 – IP Addressing and VLSM Day 3 – IPv6 Concepts 3.Ping from R2 to R1 or vice versa. Each binary bit represents a decimal number, and you can use or not use the number by placing a 1 or a 0, respectively, in the relevant column. The eight columns are as follows: Enter configuration commands, one per line. End with CNTL/Z. Router(config)#hostname RouterB 　Hardware is Lance, address is 0030.f252.3402 (bia 0030.f252.3402) BW 100000 Kbit, DLY 1000 usec, Stateful firewalls operate at Layers 3, 4, and 5 of the OSI model. They are ubiquitous on modern networks. All traffic flows are kept in a state table that is used by the firewall to check for attacks, permit or deny packets, and for inspection by the network administrator. In order to use route summarization on your network, you need to use a classless protocol (covered later), such as RIPv2, EIGRP, or OSPF. You also need to design your network in a hierarchical order, which will require careful planning and design. This means that you can’t randomly assign networks to various routers or LANs within your network. London 2 - London 2 also has 21 common bits, so it can advertise 10.1.8.0/21 to the HQ router. Campus LAN Topologies Two-Tier Campus Design—The Collapsed Core VLANs are a fairly straightforward feature which rarely requires troubleshooting. A few of the problems that you will see are mostly configuration errors. We will cover Layer 2 troubleshooting in detail on Day This topology is used mainly for WAN links. A point-to-point link is simply one in which one device has one connection to another device. You could add a secondary link connecting each device for redundancy but if the device itself fails, then you lose all connectivity. The following is a short sample configuration of a switch. I have included the switchport command, which tells the switch to act as a switch port for Layer 2, as opposed to Layer 3. This command would be added on a multilayer switch such as a 3660. Even if you are not chopping your network into smaller parts, you must still apply a subnet mask to every address used. Each network class comes with a default subnet mask, for example: R2#show ipv6 route ::/0 Purpose Layer 7 – Application Layer 0 1 2 3 4 5 6 7 8 9 A B C D E F general public, and why would they? There were no websites, no e- commerce, no mobile networks, and no social media. Even if you could afford a PC,cisco 200 301 exam price, there wasn’t much you could do with it. Now, of course, almost everybody is online. We carry out most of our day-to-day tasks using the Internet, and businesses rely on it to exist. Soon we will be using mobile devices to manage our cars and home security, to turn the coffee maker on, to set the heating level, and to set the TV to record our favorite show.
