Experiment No. Title : - Study of different types of Network cables and practically implement the cross-wired cable and straight through cable using clamping tool. Objective : - Students will understand concepts of Cabling S/W Requirement : - NA
Step 1: Strip the cable jacket about 1.5 inch down from the end. Step 2: Spread the four pairs of twisted wire apart. For Cat 5e, you can use the pull string to strip the jacket farther down if you need to, then cut the pull string. Cat 6 cables have a spine that will also need to be cut. Step 3: Untwist the wire pairs and neatly align them in the T568B orientation. Be sure not to untwist them any farther down the cable than where the jacket begins; we want to leave as much of the cable twisted as possible.
Step 4: Cut the wires as straight as possible, about 0.5 inch above the end of the jacket. Step 5: Carefully insert the wires all the way into the modular connector, making sure that each wire passes through the appropriate guides inside the connector. Step 6: Push the connector inside the crimping tool and squeeze the crimper all the way down. Step 7: Repeat steps 1-6 for the other end of the cable. Step 8: To make sure you've successfully terminated each end of the cable, use a cable tester to test each pin. When you're all done, the connectors should look like this: RESULT: Cross and Straight Cable Prepared
Title:- Configure and Understand working of network devices Hub, Switch, Routers Objective :- Students will understand working of network devices S/W Requirement :- Packet Tracer
Title:- Configure and Understand working of network devices Hub, Switch, Routers Objective :- Students will understand working of network devices S/W Requirement :- Packet Tracer
Here are router configurations: Enter the "global configuration" mode in the router. Router>enable Router#configure terminal
Enter configuration commands, one per line. End with CNTL/Z. Now, in order to configure the interface, enter the interface configuration mode as follows. General syntax can be stated as: Router(config)#interface fastEthernet 0/0 Router(config-if)# As in the interface mode, you will have to configure a static IP for the interface, which shall be acting as a "default gateway" to the entire network held by that interface. Router(config-if)#ip address 192.168.10.1 255.255.255. By default, the interface is down. You can simply get the status of each and every interface of a network management system, in packet tracer by hovering the mouse pointer over the device.In order to administratively turn the interface up/on, you must actually write-down following command: Router(config-if)#no shutdown Router(config-if)# The effect will be visible in the light that is blinking over the links. And now, set the IP address for each and every work station, statically.If you do not want to configure each and every work station's ip address statically, you will have to assign DHCP role for the router. Well, configuring DHCP role for router has been explained again in the Core Networking Labs section. RESULT: Students will understand working of various networking devices
Router(config-if)#clock rate 64000 Router(config-if)#bandwidth 64 Router(config-if)#no shutdown
Title:- Configure a network using Distance Vector routing Protocol using Packet Tracer or NS2. Objective :- Understand Routing Mechanism S/W Requirement :- Packet Tracer or NS
RouterA(config)# router rip RouterA(config-router)# version 2 RouterA(config-router)# no auto- summary RouterA(config-router)# network 10.0.0. RouterA(config-router)# network 192.168.1.
RIP uses hop count as the metric and we can only modify it using the offset-list feature which is covered in detail in Routing Filtering & Manipulation. It must be noted that offset-list feature is a protocol independent feature used for other routing protocols as well such as EIGRP. However parameters and characteristics of a RIP routing update can be modified. By default RIP version 2 updates are multicast and we can configure a Router to unicast these updates. RouterA(config)# router rip RouterA(config-router)# neighbor 192.168.1.2 RouterA(config-router)# passive-interface fa0/ The neighbor commands instructs RIP to send unicast routing updates to the specified neighbor and the passive-interface command is used to suppress multicast updates out that interface. This is usually used when a router connects on multi-access segment and we want to exchange RIP information with only a specific neighbor. We can also modify various timers associated with RIP such as the update timer which defines the rate in seconds at which RIP updates are sent. Below is the command syntax to modify various timers used by RIP. RouterA(config)# router rip RouterA(config-router)# timer basic update invalid holddown flush
