Objectives
■ Create a basic switch configuration and verify it.
■ Observe the behavior of the spanning-tree algorithm in the presence of switched network topology
changes.
Background/Preparation
Cable a network that is similar to the one in Figure 7-7. The 2950 series switch produced the configuration
output in this lab. 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 on all switches before you continue with this lab.
Task 1: Configure the Switches
Configure the hostnames and passwords, as well as the management VLAN 1 settings for each switch, as
indicated in Table 7-2. If you have problems while performing this configuration, refer to Lab 6-2, “Basic
Switch Configuration.”
Task 2: Configure the Hosts that Are Attached to the Switches
Configure the hosts as part of the same subnet as the switches. The hosts also share the same subnet mask
and the same default gateway.
Task 3: Verify Connectivity
Step 1. To verify that the hosts and switches are configured correctly, ping the switches from the hosts.
Step 2. Were the pings successful?
Step 3. If the answer is no, troubleshoot the host and switch configurations.
Task 4: Look at the VLAN Interface Information
Step 1. On both switches, type the command show interface vlan 1 at the privileged EXEC prompt.
Switch_A#show interface vlan 1
