In this lab, we worked in groups in order to configure a simple network environment in order to become more familiar working with physical networking equipment and hardware.

• x1 Cisco 1841 Router
• x2 5 Port Netgear Unmanaged Switch
• x2 Laptops/Workstations (w/ kali installed)
• x4 Ethernet Cables
• x1 Serial Cable (USB-A to RJ45)

The completed network should look similar to below:

===

1. Plug in a Serial Console Cable between the Router (Console Port) and your workstation
2. Use Device Manager to verify the COM port of the Serial Cable
3. Open PuTTY + configure settings to connect to router (Click "Open" to connect)

PuTTY Connection Settings:

Serial Line to Connect = COM Port #
Bits Per Second = 9600
Data Bits = 8
Parity = None
Stop Bits = 1
Flow Control = None
Session = Serial + COM Port #

• enable - Elevates user access to "privileged" or EXEC mode (Allows you to configure your router/switch)
• configure terminal - Changes the terminal to "global config mode" (Config Menu)
• interface <interface name here> - Enters the configuration menu for the selected interface (must be in "(config)" mode)
• ip address <IP_Address> <Subnet_Mask> - Sets the IP Address of the selected interface port (must be in "(config-interface)" mode)
• no shutdown - Enables the port (must be in "(config-interface)" mode)
• show ip interface - Shows config information on the available IP Interfaces (EXEC Mode)
• show run - Shows the current running config of the router/switch (EXEC Mode)
• exit - Command used to exit out of the current mode or setting
• end - Exits the configuration setting and returns to EXEC mode
• copy run start - Saves the current router/switch configuration to NVRAM (i.e. Configuration will be saved when the router/switch is rebooted) (EXEC Mode)
