[CCNAv6 S3] 1.2.1.7 Packet Tracer - Compare 2960 and 3560 Switches



Packet Tracer - Compare 2960 and 3560
Objective

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?
List the transmission speed of the Fast Ethernet and Gigabit Ethernet interfaces on each switch.
Are either of the two switches modular in design?
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?
What is the difference between a switch’s physical interface and the VLAN interface?
On which layers do 2960 and 3560 switches operate?
Issue the show run command to examine the configurations of the D1 and ASw-1 switches. Do you notice any differences between them?
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?
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?
Issue the show run command and examine the configurations of R1 and D1. What differences do you see between the two?
Which command allows D1 to configure an IP address on one of its physical interfaces?
Use the show ip route command on both devices. Do you see any similarities or differences between the two tables?
Now, analyze the routing table of R2 and D2. What is evident now that was not in the configuration of R1 and D1?
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?
Why were we able to ping across networks without there being a router?


END !~!

Packet Tracer – Troubleshooting Enterprise Networks 3 Addressing Table Background This activity uses a variety of technologies you have encountered during your CCNA studies, including routing, port security, EtherChannel, DHCP, NAT, PPP, and Frame Relay. Your task is to review the requirements, isolate and resolve any issues, and then document the steps you took to verify the requirements. Note: This activity begins with a partial score. Requirements DHCP ·         R1 is the DHCP server for the R1 LAN. Switching Technologies ·         Port security is configured to only allow PC1 to access S1's F0/3 interface. All violations should disable the interface. ·         Link aggregation using EtherChannel is configured on S2, S3, and S4. Routing ·         All routers are configured with OSPF process ID 1 and no routing updates should be sent across interfaces that do n...

Packet Tracer - Configuring IPv4 Static and Default Routes Addressing Table Objectives Part 1: Examine the Network and Evaluate the Need for Static Routing Part 2: Configure Static and Default Routes Part 3: Verify Connectivity Background In this activity, you will configure static and default routes. A static route is a route that is entered manually by the network administrator to create a reliable and safe route. There are four different static routes that are used in this activity: a recursive static route, a directly attached static route, a fully specified static route, and a default route. Part 1:     Examine the Network and Evaluate the Need for Static Routing a.     Looking at the topology diagram, how many networks are there in total? b.    How many networks are directly connected to R1, R2, and R3? c.     How many static routes are required by each router to reach networks that are not directly ...

Packet Tracer – Troubleshooting Standard IPv4 ACLs Addressing Table Objectives Part 1: Troubleshoot ACL Issue 1 Part 2: Troubleshoot ACL Issue 2 Part 3: Troubleshoot ACL Issue 3 Scenario This network is meant to have the following three policies implemented: ·         Hosts from the 192.168.0.0/24 network are unable to access network 10.0.0.0/8. ·         L3 can’t access any devices in network 192.168.0.0/24. ·         L3 can’t access Server1 or Server2. L3 should only access Server3. ·         Hosts from the 172.16.0.0/16 network have full access to Server1, Server2 and Server3. Note: All FTP usernames and passwords are “cisco”. No other restrictions should be in place. Unfortunately, the rules that have been implemented are not working correctly. Your task is to find and fix the errors related to the access lists on R1.
