Part 1: Compare Layer 2 and Layer 3 Switches
Part 2: Compare a Layer 3 Switch and a Router Background
In this activity, you will use various commands to examine three different switching topologies and compare
the similarities and differences between the 2960 and 3560 switches. You will also compare the routing table
of a 1941 router with a 3560 switch. Part 1: Compare Layer 2 and Layer 3 Switches
a. Examine the physical aspects of D1 and ASw-1.
Each individual switch has how many physical interfaces?
How many Fast Ethernet and Gigabit Ethernet interfaces does each switch have? 24 Fast Ethernet interfaces and 2 Gigabyte Ethernet interfaces.
List the transmission speed of the Fast Ethernet and Gigabit Ethernet interfaces on each switch. Fast Ethernet support speeds of 10/100mb/s and Gigabyte Ethernet supports speeds up to 1000mb/s
Are either of the two switches modular in design? No
b. The interface of a 3560 switch can be configured as a Layer 3 interface by entering the no switchport
command in interface configuration mode. This allows technicians to assign an IP address and subnet
mask to the interface the same way it is configured on a router’s interface.
What is the difference between a Layer 2 switch and a Layer 3 switch? A Layer 2 switch forwards based on MAC addresses when Layer 3 switches can be configured with
routing protocols in the same way a router is. © 2016 Cisco and/or its affiliates. All rights reserved. This document is Cisco Public. Page 1 of 3 Packet Tracer - Compare 2960 and 3560 Switches
What is the difference between a switch’s physical interface and the VLAN interface? The physical interface of a switch physically connects end devices to the network, when a switched
virtual Interface like an SVI or VLAN configures the switch with a IP address so that it can be managed
On which layers do 2960 and 3560 switches operate? The 2960 uses Layer 2, when the 3560 uses Layers 2 and 3.
Issue the show run command to examine the configurations of the D1 and ASw-1 switches. Do you
notice any differences between them? Yes, D1's G0/1 and G0/2 interfaces are configured with no switchport command and show an IP address
and mask. D1 has IP routing enabled.
Display the routing table on both switches using the show ip route command. Why do you think the
command does not work on ASW-1, but works on D1? D1 works since it functions on Layers 2 and 3 so it can route pakckets based on IP addresses from Layer
3. Part 2: Compare a Layer 3 Switch and a Router
a. Up until recently, switches and routers have been separate and distinct devices. The term switch was set
aside for hardware devices that function at Layer 2. Routers, on the other hand, are devices that make
forwarding decisions based on Layer 3 information. They use routing protocols to share routing
information and to communicate with other routers. Layer 3 switches, such as the 3560, can be
configured to forward Layer 3 packets. Entering the ip routing command in global configuration mode
allows Layer 3 switches to be configured with routing protocols, thereby possessing some of the same
capabilities as a router. Although similar in some forms, switches are different than in many other aspects.
Open the Physical tab on D1 and R1. Do you notice any similarities between the two? Do you notice any
differences between the two? Both the router and switch have a console port and two Gigabit Ethernet interfaces. R1 is modular so
adding interfaces is possible unlike R1's fixed Serial and Asynchronous interfaces. D1 comes out the box
with Ethernet interfaces and can only be used with copper cables when R1 can use various kinds of
Issue the show run command and examine the configurations of R1 and D1. What differences do you
see between the two? R1 and D1 have the same IP addresses configured on them but on different interfaces. The no
switchport command must be used in order to
Which command allows D1 to configure an IP address on one of its physical interfaces? The no switchport command
Use the show ip route command on both devices. Do you see any similarities or differences between the
two tables? The codes are the same except the router has an L code for local. © 2016 Cisco and/or its affiliates. All rights reserved. This document is Cisco Public. Page 2 of 3 Packet Tracer - Compare 2960 and 3560 Switches
Now, analyze the routing table of R2 and D2. What is evident now that was not in the configuration of R1
and D1? Both have EIGRP configured and both are learning networks from one another b. Verify that each topology has full connectivity by completing the following tests: Ping from PC1 to PC2 Ping from PC3 to PC4 Ping from PC5 to PC6 In all three examples, each PC is on a different network. Which device is used to provide communication
between networks? Router or multilayer switch
Why were we able to ping across networks without there being a router? A multilayer switch can route between networks as long as it is configured with an IP address and has IP
routing enabled. The no switch-port command must be used. Suggested Scoring Rubric
