Packet Tracer Challenge Each chapter also includes a culminating activity called the Packet Tracer Skills integrating Challenge. These activities require you to pull together several skills learned from the chapter†and from previous chapters and coursesâ€to suc cessfully complete one comprehensive exercise. A Word About Packet TracerPacket Tracer is a self-paced, opthalmic, interactive teaching and learning tool developed by Cisco. Lab activities are an important part of networking education. However, lab equipment can be a scarce resource. Packet Tracer provides a visual simulation of equipment and network processes to offset the challenge of particular equipment. Students can spend as much time as they like completing standard lab exercises through Packet Tracer, and have the option to work from home. Although Packet Tracer is not a transform for real equipment, it allows students to practice using a command-line porthole.This â€Å"e-doing” ability is a fundamental component of learning how to tack together routers and switches from the command line. Packet Tracer v4. x is available only to Cisco Networking Academies through the Academy Connection website.

Cable a network that is similar to the one shown in Figure 6-4. You can use any sure switch in your lab as yen as it has the required interfaces shown in Figure 6-4 and supports 802. 1Q encapsulation. The router you get must support inter-VLAN routing. The output shown in this lab is based on Cisco 2960 switches and an 1841 router.Other switch or router models may produce different output. Set up console connections to all three switches. Step 2. Clear any existing configurations on the switches. Clear NVRAM, cancel the vlan. dat file, and reload the switches. Refer to â€Å"Lab 2-1: Basic Switch Configuration (2. 5. 1)” if necessary for the procedure. After the reload is complete, use the show vlan command to confirm that only default VLANs exist and that all ports are assigned to VLAN 1.

Disable all ports on the switches using the mop up command. Ensure that the sign switch port states are inactive by disabling all ports. Use the interface setting command to simplify this task. Commands for S1 are shown here: S1(config)#interface range fa0/1-24S1(config-if-range)# cloture S1(config-if-range)#interface range gi0/1-2 S1(config-if-range)#shutdown Step 4. Re change the active user ports on S2 in access mode: S2(config)#interface fa0/6 S2(config-if)#switchport mode ac cess S2(config-if)#no shutdown S2(config-if)#interface fa0/11 S2(config-if)#switchport mode access S2(config-if)#no shutdown S2(config-if)#interface fa0/18 S2(config-if)#switchport mode access S2(config-if)#no shutdown Task 2: Perform Basic Switch Configurations Configure the S1, S2, and S3 switches according to the addressing table and the following guidelines: ¦Configure the switch hostname. ¦ Disable DNS lookup. ¦ Configure an enable mysterious password of class. ¦ Configure a password of cisco for the console connections. ¦ Configure a password of cisco for vty connections. ¦ Configure the default gateway on each switch.
