Cisco Packet Tracer Fundamentals

Flashcards based on the Cisco Packet Tracer Lecture Notes

Cisco Packet Tracer (CPT)

A software used to create network simulations and labs.

LAN Creation

Involves using network devices and end devices within CPT to simulate a local area network.

Network Devices

Include routers, switches, hubs, wireless devices, and firewalls, accessible within CPT.

End Devices

Include PCs, laptops, and servers, used to simulate computers and other endpoints in a network.

Automatic Connection

CPT feature that automatically selects the appropriate wire type for connecting devices.

Straight Cable

Indicated by a pure black wire, used to connect computers to a switch in a basic LAN setup.

Deleting Elements

Use the cross symbol to delete items in the CPT workspace; use the escape key to return to the normal cursor.

Writing in CPT

Use the clipboard icon to add text annotations, such as IP addresses, to the network diagram.

IP Configuration

Accessed through the desktop option on a device to configure IP addresses, subnet masks, and default gateways.

Static IP Assignment

Manually configuring the IP address, subnet mask, and default gateway on a device.

Command Prompt

Used within CPT to test network connectivity using the ping command.

Ping

A command used to test network connectivity between devices by sending and receiving packets.

Interface Names

Port names like FA0/1, FA0/2, etc., are displayed by enabling 'Always show port label in logical workspace' in Preferences.

DHCP Server

A server that automatically assigns IP addresses to devices on a network.

DORA Process

The process DHCP servers use to assign IP addresses which includes Discover, Offer, Request, and Acknowledge.

Broadcast Packet

A type of network packet that is sent to all devices on a network (represented as FFF or 255.255.255.255).

Unicast

One-to-one communication.

Multicast

One-to-a-group communication.

Broadcast

One-to-all communication.

Relay Agent

A tool configured on a router to forward DHCP requests from one network to another.

Router Configuration - CLI

Configuring a router through the command line interface.

Router Configuration - GUI

Configuring a router through the graphical user interface.

User Mode

The default mode when accessing a Cisco router CLI, indicated by a '>'

Privilege Mode

Accessed from user mode using the 'enable' command. Indicated by '#'.

Configuration Mode

Accessed from the privilege mode using command config t.

Configuration Interface Mode

Accessed from the configuration mode by specifying an interface.

No Shutdown

Command used on a router to activate an interface, enabling traffic flow.

Default Gateway

The IP address of the router interface that allows communication outside the local network.
