I had a dream as a young boy growing up in Pakistan to work in cyber security. I've discovered the value of respectful, active listening, thoughtful questioning, and a never-ending thirst for knowledge. I have been fortunate to learn, succeed, and remain humbled.I enjoy assisting others in developing, and as a leader, I want to have a positive influence.The idea that I am pursuing a career that will protect people and their position. I hold several credentials like Cyber Security and Networking.

Figure 1: L3-Switch as DHCP for LAN
In this article we will configure layer-3 switch for LAN and then after we will proceed to configure Layer-3 as a DHCP server for different VLANS with different network range.
Figure 2: Commands for Configuring L3-Switch as DHCP Figure 3: IP Address after DHCP DORA Process for PC1 Figure 4: IP Address after DHCP DORA Process for PC3
As output show that our DHCP is working for PC’s, and they have been getting there IP Addresses after DORA Process.
DORA Process is, D(Discover), O(Offer), R(Request), A(Acknowledge) which is conversation model between DHCP client and server for IP assignment.
In this Artice we will write about how to configure a DHCP, DNS and Web Server and for this configuration we will use Layer-3 and Layer-2 switches. DHCP Server Configuration in Layer-3 Switch! A DHCP Server is a network server that automatically provides and assigns IP addresses, default gateways and other network parameters to client devices. It relies on the standard protocol known as Dynamic Host Configuration Protocol or DHCP to respond to broadcast queries by clients. As network design above show that we have connected hosts ( PC's) to Layer-2 switches and so we are not going to assign manual IPs to these hosts, but we will configure DHCP Server for these hosts to get there IP's. In this article we will create VLANS and made there IP pools for DHCP configuration and these VLANS are 10,20 and 30. As commands below show that how we three VLANS 10,20 and 30 are created, and their name are vlan 10, vlan 20 and vlan30 respectively. Figure 2: VLANS in Layer
Figure 1: Web Server for SecurityWithBlue.com I have a fictional website which I have to host on server and then access the website through server IP . Figure 2: Manual IP Assignment to Server First, we will assign manual IP to server shown above where our website is hosted and then we will go to services and their HTTP and HTTPS are by default ON . Figure 3: HTTP and HTTPS ON by Default! Figure 4: Web Browsing for Website Go to Web Browser and put the IP Address of server which we have assign manually to a server and we will be given with our hosted website on server. Figure 5: SecurityWithBlu
Network Design for Layer 3 inter-VLAN communication. what is gateway? A gateway is a device or a software that connects two or more networks and allows data to flow between them. It can also perform functions such as protocol translation, data conversion, security filtering, or routing. I have three layer 2 switches where different networks are installed. I have to configure a layer 3 switch for inter-VLAN communication. First thing first, I will create three VLANs which I will assign IP Addresses to them which will act as default gateway for hosts connected to layer 2 switch. To create VLANs we will use the command VLAN which is built in command for VLAN creation in switch. There is one VLAN already exist in switch is default VLAN for switch that can be used as a management VLAN. Following commands are used to create three VLANs(10,20,30). Switch>enable Switch#config terminal After running above commands, we are
