CCNA - Routing and Switching
Console configuration
Accessing and configuring the cisco device using a direct, local connection through its console port. This is often the first method used to configure a new device, as it does not require the device to have any pre-existing network settings.
We go through console configuration in this short lab.
Telnet Configuration
Telnet configuration of a Cisco switch or router involves enabling and configuring the device to allow remote management over the network using the Telnet protocol. Telnet is an older protocol that provides a command-line interface for managing network devices. However, it transmits data (including passwords) in plaintext, making it less secure than SSH.
In this lab we set up Telnet protocol on Cisco switch.
SSH Login
SSH (Secure Shell) configuration on a Cisco switch or router allows secure remote access to the device's command-line interface (CLI) over an IP network. Unlike Telnet, SSH encrypts all communication, including login credentials, making it the preferred method for remote management. I explain SSH setting in this lab.
MOTD and Login Banner
MOTD (Message of the Day) and login banners are text messages displayed to users when they access the device. These banners serve as a way to convey important information, such as legal disclaimers, usage policies, or general announcements.
MAC Table
The MAC table in a switch is a database that maps MAC addresses to specific switch ports. It enables the switch to efficiently forward Ethernet frames to the correct destination without broadcasting them to all ports.
I explain how to navigate on Cisco switch to check MAC table information.
RIP Protocol in the Lab
Using the Routing Information Protocol (RIP) in a lab environment can be beneficial for several reasons, especially for those learning about networking and routing.
I present how to use RIP protocol in the lab to simplify routing and easy configuration.
Routing on a Stick
"Routing on a Stick" (ROAS) is a network configuration where a single physical interface on a router is used to route traffic between multiple VLANs.
Let's go to Routing on a Stick lab to explain how this routing works.
DHCP Protocol
Dynamic Host Configuration Protocol (DHCP) is a network management protocol used to automatically assign IP addresses and other network configuration parameters to devices (clients) on a network. It eliminates the need for manual configuration, making network management simpler and more efficient.
In this lab I go through DHCP settings on Cisco routers.
