Lab 1 CLI Navigation This lab covers the most basic skills for accessing and using the command-line interface (CLI) on a Cisco router or switch. Many of the small, picky details of how the CLI works cannot be seen by reading a book; this lab hopes to complete the coverage of those basics. In particular, the objectives of this lab are as follows: ■

Use IOS CLI help features

■

Describe the differences between , enable, and config modes

■

Describe the difference between EXEC commands and configuration commands

■

Move among , enable, and configuration modes

Scenario This lab contains two main steps. The first step focuses on the basics of the CLI, and the second step examines different CLI modes and how to move between them. The video takes the following actions at the two steps: Step 1.

From the console port, the logs in to a router and experiments with EXEC mode. This step shows how to get command-line help.

Step 2.

The moves among EXEC mode, privileged (enable) EXEC mode, and configuration mode. This step demonstrates some commands that might be allowed only in a particular mode.

Initial Configurations Many labs in the CVIP have meaningful initial configurations. If you use this lab at the suggested point in your study, you will not yet have seen some of the configurations. However, for completeness, Example 1-1 shows the initial configuration of router R1 at the beginning of the lab. The parts of R1’s configuration that are not relevant to this lab have been omitted. Example 1-1 hostname R1

Initial Configuration for R1

Ending Configurations This lab ends with the configuration unchanged.

Video Presentation Reference The video presents figures, tables, and text with short lectures before showing the CLI of the router. This section simply lists these figures and tables for reference. Figure 1-1 shows a diagram of the network used in this example. Figure 1-1

Lab 2 Router Configuration This lab demonstrates the mechanics of configuring a Cisco router and how to copy configuration files. The objectives of this lab are the following: ■

Describe the configuration process using different configuration modes

■

Recognize the command prompts seen in different configuration modes

■

Copy configuration files using the copy command

Scenario This lab contains two primary steps. The first step focuses on an example of moving around in configuration mode, with the goal of explaining the process rather than the specific commands. The second step focuses on how to copy configuration files on a Cisco router. The video references these two main steps as follows: Step 1.

Using configuration mode

Step 2.

Viewing and copying configuration files in NVRAM, RAM, and TFTP servers

Initial Configurations The only router shown in this video begins with almost no configuration other than a host name. Example 2-1 lists the hostname configuration for reference. Example 2-1

Initial Configuration for Router R1

hostname R1

Ending Configurations By the end of the lab, R1’s running and startup configuration files should be identical. The video also shows a couple of other configuration items. Example 2-2 lists the ending configuration after all steps in the lab.

Lab 3 Switch Basics This lab reviews the logic of how switches learn entries for their MAC address tables and make forwarding and filtering decisions based on those tables; it also shows some of the most basic configuration settings on a Cisco LAN switch. In particular, the objectives of this lab are as follows: ■

Predict the types of entries to be found in a switch’s MAC address table

■

Describe how switches make forwarding/filtering decisions

■

Configure the following: — Interface speed and duplex settings — Switch IP address and default gateway

Scenario This lab contains two main steps, as follows: Step 1.

Observe the addition of new MAC address table entries

Step 2.

Configure basic settings: ■

Interface speed and duplex

■

IP address and default gateway

Initial Configurations The two switches in this lab begin with very little configuration—each switch simply has a hostname configured. Examples 3-1 and 3-2 list the hostname configurations for completeness. Example 3-1

Initial Configuration for Sw1

hostname Sw1

Example 3-2 hostname Sw2

Initial Configuration for Sw2

Ending Configurations This lab adds some configuration commands to both Sw1 and Sw2. Examples 3-3 and 3-4 show the configuration added during the lab. Example 3-3

Configuration on Sw1 Added During This Lab

Lab 4 VLANs This lab shows how to use the commands required to configure virtual LANs (VLANs) on Cisco IOS Software-based switches, in addition to a few of the commands used to examine VLAN operations. In particular, the objectives of this lab are as follows: ■

Configure VLANs on Cisco switches

■

Configure the VTP mode on Cisco switches

■

Determine the status of VLAN trunks

■

Configure 802.1Q trunking between two Cisco switches

Scenario This lab contains two main steps, as follows: Step 1.

Use a three-step process to create the first VLAN on a switch: Configure VTP mode Create a VLAN Add interfaces to that VLAN

Step 2.

Examine and configure 802.1Q trunking between two switches

Initial Configurations The two switches in this lab begin with some basic configuration. First, host switches have their hostnames configured. Second, the switch ports connected to the PCs have been configured to use the spanning-tree portfast command, which causes these end- ports not to wait on Spanning Tree Protocol (STP) timers when the ports are istratively enabled. However, all VLAN configurations has been removed before this lab begins. Examples 4-1 and 4-2 show the basic initial configurations for both switches in this lab. Example 4-1 Initial Configuration for Sw1 hostname Sw1 ! interface FastEthernet 0/11 spanning-tree portfast ! interface FastEthernet 0/13

Ending Configurations This lab adds some configuration commands to both Sw1 and Sw2; however, it does not change any of the earlier configurations. Examples 4-3 and 4-4 show the configuration added during the lab. Example 4-3

Configuration on Sw1 Added During this Lab

vtp transparent ! vlan 11 name thisisvlan11 ! interface FastEthernet 0/11 switchport access vlan 11 ! interface FastEthernet 0/13 switchport access vlan 11 ! interface FastEthernet 0/23 switchport mode trunk
