VLAN , VTP & DHCP on cisco switch through Packet Tracer 5.3

vlan (vitual lan ) vtp (vlan trunking protocol ) & DHCP on multilayer cisco switch on Packet Tracer

VLANs and Trunks for Beginners

A quick tutorial on how to set up VLANs and Trunks for the Cisco CCNA. Using Packet Tracer, I demonstrate the basics of VLANs and how they function. In this series of tutorials, I will discuss the different types of VLANs: Default, Data Native and Management, and how they function.

Class Notes

1. TCP/IP
Is technically a Protcol Suite
IP Routes Traffic
Layer 3 OSI Model Network
Routable Networks (sub networks)
TCP controls transmission between connected systems
Layer 4 OSI Model Transport
Windowing is the process of sending data from one computer to another in TCP/IP version 4
2. How TCP/IP Works
IP Addresses -- Every device on a TCP/IP network needs an individual IP Address
DNS (Domain Name Service/Server) resolves Domain names into IP Addreses
DHCP (Dynamic Host Control Protcol) Servers automatically assign IP information to clients for a specific time period (Lease). Clients try to renew leases at 50% expiration point.
Default Gateway (Router) connects networks. If an IP Address cannot be found on the local network the computer tries to use the Default Gateway to find the target.
Subnets and Subnet Masking -- Subnets are individual networks. Subnet Masks divide IP Addresses in Subnet Number and Host Number
What the Number Mean
IP Addresses and Subnet Masks are made of 4 Octets of Bits
128-64-32-16-8-4-2-1
Subnet Masking
IP Addresses contain the Subnet Number and Host Number. The Subnet Mask tells you where the subnet number ends and the host number begins.
Classful Networks A, B, C,D,E Gone now use CIDR
The Highest Address in a Subnet Range is the Broadcast address
To determine the number of subnets (n is the number of bits used)= 2n
To determine number of Hosts = 2n -2

IP Addressing and subnetting

This is an introduction to IPv4 addressing and Subnetting. But the same method can be used for IPv6.

(Please excuse the quality of this video...it is old and it was one of my very first videos...this video started out to be a JOKE...and it eventually became a hit...who knew?)

My complete CCNA course is now available on UDEMY at 68% OFF with coupon code: CERTDOC68%

For those of you that are looking for a more complete understanding of IPv4, HEX Conversions, Vlans, Routers & other courses related to Cisco and/or the CCNA certification, I'm happy to announce that I now have full courses available at The Networking Doctors website or the UDEMY website...just click on http://www.thenetworkingdoctors.com or https://www.udemy.com!

Also, for those wondering why I start by 2...I have a YT video called "Counting by 2 and double as you go" that will clarify the mothod to my madness ;)

Hope to see you as one of my online students!
