How to Access Cisco Catalyst & Switch CLI

Leave a Comment / CCNA / By

This article is explain How to Access Cisco Catalyst & Switch CLI , Cisco catalyst switches & Accessing the cisco IOS CLI. Cisco uses the concept of a command-line interface (CLI) with its router products and most of its Catalyst LAN switch products. The CLI may be a text-based interface during which the user, typically a network engineer, enters a text command and presses Enter. Pressing Enter sends the command to the switch, which tells …

How can we Cabling the Console Connection

Leave a Comment / CCNA / By

How can we Cabling the Console Connection in this article is explaining how to cabling console connection in PC using switches and USB. The physical console connection, both old and new, uses three main components: the physical console port on the switch, a physical interface on the PC, and a cable that works with the console and serial ports. However, the physical cabling details have changed slowly over time, mainly due to advances and changes …

What are the LAN Switching Concepts

Leave a Comment / CCNA / By

LAN Switching Concepts A modern Ethernet LAN connects user devices also as servers into some switches, with the switches then connecting to every other, sometimes during a design like Figure 7-1. a part of the LAN, called a campus LAN, supports the end user population as shown on the left of the figure. user devices connect to LAN switches, which in turn connect to other switches so that a path exists to the rest of …

Verifying and Analyzing Ethernet Switching

Leave a Comment / CCNA / By

Verifying and Analyzing Ethernet Switching A Cisco Catalyst switch comes from the factory able to switch frames. All you’ve got to do is connect the facility cable, connect the Ethernet cables, and therefore the switch starts switching incoming frames. Connect multiple switches together, and that they are able to forward frames between the switches also . and therefore the big reason behind this default behavior has to do with the default settings on the switches. Cisco Catalyst switches …

Overview of the TCP/IP Networking Model

Leave a Comment / CCNA / By

This blog is on TCP/IP networking model in that Overview has given as well as there different layer has been explained. Overview The TCP/IP model both defines and references a large collection of protocols that allow computers to communicate. To define a protocol, TCP/IP uses documents called Requests For Comments (RFC). (You can find these RFCs using any online search engine.) The TCP/IP model also avoids repeating work already done by another standards body or …
