Observe the behavior of spanning tree algorithm in presence of switched network topology changes. Background Preparation Cable a network similar to one of the diagram. The configuration output used in this lab is produced from a 2950 series switch. Any other switch used may produce different output. The following steps are to be executed on each switch unless specifically instructed otherwise. Start a Hyperterminal session. Step 1 Configure the switches Configure the hostname access and command mode passwords as well as the management LAN settings. These values are shown in the chart. If problems occur while performing this configuration refer to the Basic Switch Configuration lab. 1 - 4 CCNA 3 Switching Basics and Intermediate Routing v 3.0 - Lab 7.2.6 Copyright 2003 Cisco Systems Inc. Step 2 Configure the hosts attached to the switches Configure the host to use the same IP subnet for the address mask and default gateway as on the switch. Step 3 Verify connectivity a. To verify that the hosts and switches are correctly configured ping the switches from the hosts. b. Were the pings successful c. If the answer is no troubleshoot the hosts and switches configurations. Step 4 Look at the show interface information a. On both switches type the command show interface vlani at the privileged exec prompt as follows Switch_A show interface vlan 1 b. What is the MAC address of this switch __ Switch_B show interface vlan 1 c.
