Setting up a Windows 10 VM

• At "Sign-In with Microsoft Screen" - Select "Domain Join Instead"

Internet settings

• On the top of your VMware Workstation Window, there is a tab titled “VM”
• Click “VM” and go to “Settings”
• Select the Network Adapter setting and change the network connection from NAT to Bridged.
• Go to the search bar of your VM and search for Windows Firewall. On the left of the firewall options window, there should be an option to Turn Windows Firewall On or Off
• Select OFF for both Private and Public Network Settings. (Turn back on once the lab is complete!!)

Notes

ipconfig

• Displays all current TCP/IP network configuration values
• Run from the command line

ping

• Tests reachability of a host on an Internet Protocol network
• Run by typing ping followed by the IP you want to test

tracert

• Displays possible routes and measures transit delays of packets across an Internet Protocol network
• Run by typing tracert followed by the link/IP you want to test

nslookup

• Queries the Domain Name System (DNS) to obtain the mapping between a domain name and IP address or other DNS records
• Run by typing nslookup followed by the link/IP you want to test

How do you deploy workstations and switches in Packet Tracer?

Network Devices and End Devices tabs

How do connect these devices with cables?

Connections tab

How do you access the command-line terminal on a Packet Tracer PC?

Click on the PC, click desktop, click command prompt

9/10/2021 (Lab 2-2)

What is a MAC address and what are its components?

A media access control address is a unique identifier assigned to a network interface controller for use as a network address in communications within a network segment. A MAC address consists of two parts. The Block ID is the first six characters of a MAC address. The Device ID is the remaining six characters. The Block ID is unique to the manufacturer.

How to get a MAC address.

Use the command prompt and type ipconfig /all

What is Wireshark and how to use it.

Wireshark is a free and open-source packet analyzer. To use Wireshark choose a connection and click start.

How to find a protocol in Wireshark.

The protocol column

9/21/2021

IP Addresses

• Class A - 10 (1 Octet)
• Class B - 172.10 (2 Octets)
• Class C - 192.10.10 (3 Octets)
• 32 bits in an IP
• /24 is subnet mask (short for 255.255.255.0)
• [192.16.32][.8] = [Network][Host]
• 1 = on; 0 = off

Default Gateway

• Router address
• All info goes in and out of the default gateway

Lab 4-2

How do you set the gateway address on a workstation in Packet Tracer?

In the config tab on the device's settings

How do you set the IP and subnet mask on different interfaces of a multilayer switch?

Set for each port in the switch's config ex. FastEthernet0/1

How do you enter simulation mode in Packet Tracer?

Bottom right simulation button

How do you set which types of packets you want to see in Simulation Mode?

Click show all/none and then edit filters

Lab 4-3

• To save router configs go to the config tab and click save under NVRAM
• TURN ON PORTS

Lab 5-1

To connect devices to a router, assign IP information in the interface. Change the third octet of the IP to separate networks.

Lab 7-2

I struggled a lot with this lab from the subnetting setup to intricate mistakes in packet tracer. I took a lot of time to meticulously comb through IP configurations, ports, and cable connections to solve my issues.

Lab 9-1

The most important takeaway I had from this lab was to triple-check your numbers. There were several instances where I was routing to the wrong place by simply mistyping a single number.

Lab 9-2

After the last lab, I was significantly more comfortable dealing with static routing. I did however have an issue with routing to the same network. Instead of routing to the separate network, I routed to the same .0 network address. I eventually realized my mistake and changed it to the appropriate network.

Lab 10-1

Being familiar with RIP from previous labs, the turned out fairly easy. The only thing I would remind myself about is to RIP to the network directly connected to a router.

Lab 11-1

Similar to the last few labs, the most important aspect when it comes to programming VLANs is to be extremely thorough and meticulous. Make sure that all the devices that you are working with are connected to the right port and are assigned to the correct VLAN. When connecting switches, use cross-over cables and the fastest port on the switch. Also remember to make it a trunk port and select all the VLANs you need.
