Builder switch my brother stable this topology Cisco switch 2960 as one and another switch 2960 s2 and devices to pcs We see - a PC - be Use the straight through cable to connect for Saturn at six - PC a Unless you for Saturn at 18 - PCB And finally the connection between switches using for settlement in both sides This is the dressing-table Okay, as well on interface vlan1 the IPRs 1.11 subnet mask 255 255 255 0 a Su also ambolyn wan IP others 1.12? submit mask design Pca Network interface cards IP others 1.1 same subnet mask and PCB Never interface cards IP address 1.2 and same subnet mask The purpose of layer challenge which is to deliver eternal phrase to host devices on the local network The switch records caused my others that our bicycle on the network and maps don't smack others hands to its own patents, which ports This process is called at building the MAC address table When a switch receives Frame from a PC it examines the frame cells and destination MAC addresses The source MAC address is recorded and map it to the switch port from which it arrived That the destination MAC addresses is looking in the other stable If the destination MAC address is a noun address Then the frame is for water out of the corresponding switch or associated with that MAC address if the MAC address is now the frame is broadcasted of All switch ports, except the one from which it came It is important to observe Understand the function of a switch in how it delivers the data on the network The way a switch operates has implications for the network administrators Whose job it is to ensure secure and consistent network communication Make sure that the switches have been arrested and have no startup configurations If you are we sure contact your instructor Required resources two switches Cisco 2960 2 pcs with widows and theater Consume cables Ethernet cables in my case. I'm using agar tracer The first attempt at interfaces in Cisco 2960 switches are Auto sensing an Ethernet straight through cable may be use it between switches as well. And as to If using another model Cisco switch, it may be necessary to use an Ethernet crossover cable Built and configure the network Cable the network according the topology already completed on packet tracer configure PC host You see the receipt able to configure PCA in PCB PCA 1 I 2 as you see a 1.1 Subnet mask 255 255 255 0 Now the forgot way no Deanna's PCB I Pay less when I do a 16 1 dot 2 same subnet mask Ready Initialize reload switches necessary Ok as an example Consult from PCI rs-232 port 2 console port on switches 1 On PCH is the terminal the ok Enter Ok, for example If the switch has previous configurations you can erase the the contents of the switch using the following comment Use the enable command to access the private a sh absent mouth Ok. Now you are privileged access mode then use the following comment here eyes Start up - coffee enter enter to confirm and the lad Belong that that ok, they led the villa Database enter enter to confirm again Reload the switch Okay, this is the example to erase the content if the switch has previous configurations Okay Do this also on s2? S2 has previous configurations? Ok Other How you can verify if the switch Has no previous configurations use show running config This comment It's not permitted on user access mode. So use the enable comment or since the privileged access mode And use the show running country now, you can see all configurations, press space No configurations on interfaces no IP on belong Belong one or IP and is shut down? no configurations from lines so now you can see there are no Configurations, ok Configure basic settings for each switch Ok configure device name And access to global configuration mode with a configure terminal command Ok, now you are on global configuration mode And set the hostname According the topology, this is s1 Ok First name as one Configure IP address is listed in the other asset table Ok Long as one on belong one 1.11 submit mask 255 255 255 0 the interface vlan1 Configure the IP address 192 168 1 that 11 subnet mask Enabled interface with the nation' down comment Ok Assign Cisco as the console and BTY passwords Ok, and you are in the interface configuration vault now exit to go the global configuration mode and Set the password for console and vty first of all on console and you need to access the line configuration mode with the following command line console 0 Because there is only one console 0 Ok, now you are in the line configuration mode and set the password Cisco Enter and enable the password using the login comments Now coffee here on vty You can use the exit command to go from the line configuration mode to global configuration mode but anyway, you can go directly from Microsoft to line vty for example from 0 to 15 Lines from 0 to 15. There are 16 lines Then after the use the password Cisco and enable with the login comments Ok enable the password Now assign class is the privilege exit password And use the exit command to go from like configuration mode to global configuration mode and set the right village accept password Okay enable secret class. Okay. This is the password class For enable comment great adder and ready Okay do this on as two From PCB connects to rs-232 go to Lucas all And use the terminal, okay Then coffee or the switch s2 after And verify this which is erase it There are there are no previous configurations Start to configure this in able to access the privilege x ik mode configure terminal to access the global configuration mode The PI's name was named as to Set the IP address Interface Review the addressing table on Boleyn Wan this IP address and subnet mask interface belong one IP address We need to 168 168 112 Subnet mask Mode shut down to enable the interface Okay Now configure the passwords Exit from interface configuration exit on global configuration mode Go to line console 0 The password is Cisco enable the password with login gold tool you can exit from line configuration mode and go to block configuration mode the access line vty 0 to 15 lines Set the password also cisco and logging exit on global configuration mode said the Enable secret password that is class in disguise And ready now it's a mean the switch mark other stable a Switch alerts mark addresses and builds McCotter stable is not what devices initiate communication on the network a Record network device mode adverse suit open our common prom on pc a and PCB and type ipconfig hall What are the Ethernet adapter for physical addresses Ok on pc we close the terminal and go to command prompt Verify the Mikado's with IP config space slash all commands This is the Mikado's Ok, but this is for PCB for PCB Okay, this is the McCullers On pc I close the terminal got common from an IP config space slash all space this is the MAC address Bloody Consolidated switches wanna sue and type the Show interface for certain at one common in each switch The IPCA is connected using a console cable to as one So access the as one using the terminal And just Show it the face has entered at one but You should insert this common privilege exit mode use the exit comma to go for global configuration mode to privileged Excel modes and Just here use the show improv is for set another one comment Okay, remember positive net is the interface connected to the another switch? Okay After Space This is the result Also on switch s2 PCB is connected to the console or switch to PCB close command prompt go to terminal to Access the console log as to exit from global configuration mode and on privileged access mode Use the show interface for certain l1 comma On the second line of the common output, what is the Howard address or Bournemouth in address BIA as one for certain environment others Okay, as well PCA as one This line This is the same Okay PCB this Okay Okay, they are different Also mark addresses on PCI and PCB they are different Display the swish marketer stable Consolatory chess - and build a Mikado stable both before and after running network communication test with pain Okay lock switch to is connected to PCB using console then use the Establish a connection to s 2 and enter privileged access modes Okay, this connection is already completed between PCB and has to dysentery console cable In private logics in multi - Oh mark other stable and procedure Ok honest to the terminal Chau MAC address table Ok Even through there has been no network communication initiated across the network now use of pain It is possible that the switch has learned that mark adams from its connection to the pc and the other switch Are there any more others is recorded in the marketers table? Ok, I have only one line This is the faceted net one, this is the faceted one port This port on switch to Facet another one is connected to as one And revealed this Makati with zero zero zero two one six four seven six two zero one Reviewed is The switch one for settlement zero one mark address Is zero zero zero two one six four seven six two zero one this MAC address So as to on faceted one Can learn the MAC address of Acetone at one of us one Thing is this Mikado's? And Thing is associated with facet or network port on s2 The switch may have one or more MAC addresses in its table, based on whether or not the students entered a ping command when configuring the network. The switch will most likely have learned MAC addresses through S1’s F0/1 switch port. The switch will record multiple MAC addresses of hosts learned through the connection to the other switch on F0/1 What MAC addresses are recorded in the table? To which switch ports are they mapped and to which devices do they belong Ignore MAC addresses that are mapped to the CPU There may be multiple MAC addresses recorded in the MAC address table, especially MAC addresses learned through S1’s F0/1 switch port. In the example, the S1 F0/1 MAC address is mapped to S2 F0/1. the S1 F0/1 MAC address is mapped to S2 F0/1. If you had not previously recorded MAC addresses on the network devices in step one How could you tell which devices the MAC addresses belong to? Using only the output from the show mac address-table command? Does it work in all scenarios? The output of the show mac address-table command shows the port that the MAC address was learned on. In most cases this would identify which network device the MAC address belongs to, except in the case of multiple MAC addresses associated to the same port. This happens when switches are connected to other switches and record all of the MAC addresses for devices connected to the other switch. Here they assume our other stable and display the MAC address table again In publish X in multi pyramid other stable dynamic and Preciado Okay clear mark the rest - table dynamic enter Quickly type show market a stable game better Does the mark other stable have any others in it for villain one? Other other mark others is listed No. You will discover that the MAC address for the other switch’s F0/1 switch port has been quickly reinserted in the MAC address table. Okay, remember this is the MAC address Remember you are on switch to here and this is the MAC address of Faceted wall of switch one as one Is learn it on port for settlement one is to Wait 10 seconds type the shock mark other stable command and press Enter Are there new addresses in the mikado stable? Ok Wait at least 10 seconds, then repeat show mark at the stable command unless to The same line present There may be more much addresses in the table may be the MAC address of PCIe From PCP Biff their devices on the network and observe the switch mark other stable From PCP open comma prompt and type ARP optional Ok, go to PCB. Okay, this is PCP close the terminal open command prompt Review the mikado stable using ARP of sugar and now entries found Not including multicast or broadcast addresses how many bytes IP to mark other spells have been learned by ARP Okay The ARP cache may have no entries in it Or it may have the gateway IP address too much other swapping From BC become a broad-base PCI as long and as - Okay first of all things - PCA PCA is Close the terminal of PCA and go to command prompt to reveal this IP of PCA 1.1. So go back to PCB the Pink PCA 1 i2 160 a 1.1 enter success Pink s1 Remember as one on the other scene table was configurate when what that 11 and has to 1.12 Okay, PCA Sorry Being from PCB - one that 11 that is as well Success and pink one that 12 and sorry Pink 1.12 enter Success Did all devices helps us successful replies, if not check your cable and IP configurations Okay, if the network was capelet and configured correctly the answer should be yes in the in all cases Okay success in all cases the from our console connection to us to enter show mark other stable common Okay, and close the common prom go to terminal that is connected to s - Connected to s to show mark other stable other Now you have at least four lines Okay with the type dynamic Three lurid on positive at one and one element on faceted 18 Okay, and go back here and look at this Okay This MAC address 0 0 2 1 6 4 7 6 6 2 0 1 Is learned that on facet turn at 1 and This mark is the MAC address of faceted. Net one on this one Okay 0 0 2 1 6 4 7 6 2 0 1 this mark others for set another one on this one Also also this This mark 0 0 3 0 F 2 5 1 6 BB to Healer that on for settlement one thing. Is this the mark others of PCI 0 0 3 0 F 2 5 1 6 VV to the MAC address of PCA And this MAC address 0 0 0 2 1 7 a 3 C 0 7 1 is murdered on for satellite 18 on this interface on facilitating This is the mark others of PCB the MAC address PCB okay, is this 0 0 0 2 was having a 3 c 0 7 1 and Finally an additional MAC address 0 0 is 0 of 7 1 a 2 3 2 0 Try to find this MAC address For example from pci-x the console connection to as one is in terminal And just the common enter password Cisco Enable common password class Now you are privileged exit mode and use show interface vlan1 You know how you have this advert 0 0 is here F7 1 a 2 3 2 0 is the MAC address of belong wrong or as one Ok go to TC D 0 0 is 0 F 7 1 8 2 3 2 0 This is the MAC address or belong 1 on as 1 Because from PCB The the pings were made to Us to belong one as Well on belong on PC I Did all devices have successful replies, if not check your cabling and IP configurations As the switch added additional MAC addresses to the McCotter stable. If so, which addresses and devices There may only be one additional mark addresses not being added to the table most likely the mark address of PCIe There are additional MAC address mapping added to the table for example, the The mark address of Faceted well known as well The mark others of PCB the MAC address of PCA and the mark others of belong one or as one From PCB open comma prob retype ARP of sugar and go to command prompt Happy option right now. You have three lines the MAC address of pca With with its IP address the MAC address of Belong one on as one with the IP address mark others Belong 1 or as two with the IPS The PCP ARP cache have additional address for all network devices that were sent pigs Yes, at least three additional lines with the IP addresses and mark others On internet networks data is delivered to devices by their MAC addresses for this to happen such as pcs dynamically built ARP cache mark, Alice's tables With only a few computers on the network this process seems fairly easy What might be some of the challenges larger networks Happy broadcasts could cause Broadcast storms because ARP and switch mark tables do not authenticate or validate the IP other system of others It would be easy to spoof a device on the network Thank you You
