Background/Preparation<br />

Cable a network that is similar to the one in Figure 6-13. The 2950 switch produced the configuration output<br />

in this lab. Another switch might produce different output. Instructions are also provided for the 1900<br />

series switch, which initially displays a User Interface Menu. Select the Comm<strong>and</strong> Line option from the<br />

menu to perform the steps for this lab.<br />

Start a HyperTerminal session.<br />

Implement the procedure documented in Appendix B before you continue with this lab.<br />

Task 1: Configure the Switch<br />

Configure the hostname <strong>and</strong> passwords, as well as the management VLAN 1 settings for the switch, as<br />

indicated in Table 6-9. If you have problems while performing this configuration, refer to Curriculum<br />

Lab 6-2, “Basic Switch Configuration (6.2.2).”<br />

Task 2: Configure the Host that Is Attached to the Switch<br />

Configure the host to use the same subnet for addresses, masks, <strong>and</strong> the default gateway as the switch.<br />

Task 3: Verify Connectivity<br />

To verify that the host <strong>and</strong> switch are correctly configured, ping the switch IP address from the host.<br />

Was the ping successful? Yes<br />

If the answer is no, troubleshoot the host <strong>and</strong> switch configurations.<br />

Task 4: Reset the Console Password<br />

Step 1. Have a classmate change the console <strong>and</strong> VTY passwords on the switch, save the changes to<br />

the startup-config file, <strong>and</strong> reload the switch.<br />

Step 2. Without knowing the passwords, try to gain access to the switch.<br />

Task 5: Recover Access to the Switch<br />

Step 1. Make sure that a PC is connected to the console port <strong>and</strong> that a HyperTerminal window is<br />

open.<br />

Step 2. Power off the switch <strong>and</strong> turn it back on by holding down the Mode button on the front of the<br />

switch at the same time that the switch is powered on. Release the Mode button a few seconds<br />

after the STAT LED is no longer lit.<br />

Step 3. The following should be displayed:<br />
