Lab 5.1.5-5.1.7 – Repeaters and Hubs

Information:

- This topology consists of 8 hosts along with 2 hubs and 1 repeater in the network.

Tips:

a) The Packet Tracer “i” located on the upper right of each page and device will give information pertaining to that certain device or topology.

b) In simulation, the “i” next to the scenario drop down list will give information about the specific scenario.

c) In simulation, clicking on the packets will show OSI layer information.

Procedures:

a) In the topology mode, add three (3) additional repeaters between the two (2) hubs.

b) In simulation mode, create a new scenario.

c) Send a packet from PC4 to PC0 and a packet from PC5 to PC1 at different times so that the packets will not collide.

d) Before running the simulation, click on the individual packets on PC4 and PC5 to review the packet and OSI information. Next, run the simulation.

e) After the first simulation, repeat step 3 except the packets does collide this time. Then repeat step 4.

f) After the packets arrive to Hub1, click on the packet that leaves Hub1 and propagates to Repeater0.

Questions:

a) What is the purpose of a hub and repeater in this network?

b) What type of medium is being used to connect the hosts to the hubs and the repeater to the hubs?

c) How many collision domain(s) does this network contain?
