Spanning Tree

OBJECTIVE: In this lab you will become familiar with following concepts:

• How spanning tree works

For more information:

• Cisco Routers and Switches /
• 3500XL Commands
• 2600 XM Commands

Note:

LAB:

1. Complete Work on SPT-Lab
2. IMPORTANT: We have been experiencing problems with Xyplex Servers. You can directly connect your computer to the Switch [1].

Submission (everything must be typed / use computer / don't forget cover sheet):

1. Draw a complete diagram of the network (do not include the server, Xyplex6 etc.) Include the following in your diagram (your diagram must look something like this; make sure all the details are shown):
   1. All cable types, MAC addresses, IP addresses,
   2. Switch ports and their MAC address, Switch ID, Which port is blocked and which is forwarding,
   3. Hub ID (MAC),
   4. The direction which the packet travels when you run a ping command (you can show this for only one PC). This must match your MAC-Table you obtained from the switch - this will be the spanning-tree.
   5. Switch/Hub Type (e.g., Cisco model)
   6. For each PC make sure you indicate the Eth, its IP address, and PC name (e.g., A)
2. You do not have to answer any of the questions in the Lab.
