392 Switching Basics and Intermediate Routing CCNA 3 Labs and Study Guide
Background/Preparation
Important Note: The use of Catalyst 2950 switches is not appropriate for this lab, because those switches support
only 802.1q trunking.
Trunking changes the formatting of the packets. The ports need to be in agreement as to which format is
being used to transmit data on the trunk, or no data will be passed. If different trunking encapsulation
occurs on the two ends of the link, they will not able to communicate. A similar situation will occur if one
of your ports is configured in trunking mode (unconditionally) and the other one is in access mode (unconditionally).
When you are managing a switch, the management domain is always VLAN 1. The network administrator’s
workstation must have access to a port in the VLAN 1 management domain. All ports are assigned to
VLAN 1 by default. This lab will help demonstrate how you can use VLANs to separate traffic and reduce
broadcast domains.
Cable a network that is similar to the one in Figure 9-4. The configuration output used in this lab is produced
from a 2900 switch. Another switch might produce different output. You should execute the following
steps on each switch unless you are specifically instructed otherwise.
Start a HyperTerminal session.
Implement the procedure documented in Appendix B, “Erasing and Reloading the Switch,” before you
continue with this lab.
Task 1: Configure the Switch
Configure the hostname, access, and command mode passwords, as well as the management LAN settings.
These values are shown in Table 9-2. If you have problems while performing this configuration, refer to
Lab 6-2, “Basic Switch Configuration.”
Task 2: Configure the Hosts Attached to the Switch
Configure the host to use the same subnet for addresses, masks, and the default gateway as the switch.
Task 3: Verify Connectivity
To verify that the hosts and switch are correctly configured, ping the switch from the hosts.
Were the pings successful? Yes
If the answer is no, troubleshoot the hosts and switch configurations.
Task 4: Display the VLAN Interface Information
On Switch_A, enter the command show vlan at the privileged EXEC mode prompt.
Switch_A#show vlan
Switch_A#show vlan
VLAN Name Status Ports
