Cisco Packet Tracer and GNS3 are powerful network simulation and emulation tools. They are used for learning. They are also used for practicing and testing network configurations. However, they are designed for different audiences and purposes, and they operate on fundamentally different principles.
Cisco Packet Tracer is a simulator. It is a self-contained, lightweight application that uses simplified models of networking devices and protocols. Its primary goal is to provide a beginner-friendly environment for learning the basics of Cisco networking. It is especially aimed at students in the Cisco Networking Academy.
GNS3 (Graphical Network Simulator-3) is an emulator. It doesn’t simulate devices itself. Instead, it acts as a graphical front-end to run real, unmodified operating system images. They are (like Cisco IOS, Juniper JunOS, VyOS, etc.) inside virtual machines or containers. It creates a realistic lab environment. This closely mirrors real-world hardware. This setup is ideal for advanced study. It is also perfect for certification preparation, like CCNP/CCIE. Additionally, it is useful for proof-of-concept testing for production networks.
Comparison Table: Packet Tracer vs. GNS3
Feature
Cisco Packet Tracer
GNS3
Core Technology
Simulation (Proprietary models of devices & protocols)
Emulation (Front-end for running real OS images via QEMU, Dynamips, VirtualBox/VMware)
Free and Open-Source (But requires your own device images, which may require a valid Cisco service contract)
Realism & Accuracy
Good for fundamentals. Some commands and behaviors are simplified or may not work exactly as on real hardware. Some advanced features are missing.
Very High. Uses real IOS images, so behavior is identical to physical hardware. Supports a vast range of advanced features and platforms.
Supported Devices
Limited to Cisco’s included devices (routers, switches, firewalls, endpoints, IoT). Easy to drag-and-drop.
Vast and Extensible. It can run Cisco IOS, ASA, and Nexus. It supports ASAv and many non-Cisco devices like Juniper, Arista, and Palo Alto. It also works with Linux and Windows.
Hardware Requirements
Historically weak for modern L2 switching. Relies on IOU/IOL images (hard to get) or uses Ethernet switches in the connected hypervisor (e.g., VMware NAT network). The GNS3 VM helps bridge this gap.
Very High. Requires a powerful CPU, ample RAM, and significant storage, especially for running multiple devices.
Ease of Use
Very Easy. Intuitive GUI, simple setup, everything is included in the installer.
Moderate to Complex. Requires sourcing your own OS images and initial setup and integration with a hypervisor (like VMware Workstation).
Switching Support
Excellent simulated Layer 2 switching. Easy to create complex switched networks with VLANs, STP, etc.
Excellent. Can easily bridge virtual networks to physical NICs, cloud platforms (AWS, Azure), and other VMs on the host.
Use Case
Advanced labs, multi-vendor environments, CCNP/CCIE preparation, and testing complex production configurations.
Advanced labs, multi-vendor environments, CCNP/CCIE preparation, testing complex production configurations.
Detailed Differences Explained
Technology (Simulation vs. Emulation):
Think of Packet Tracer as a video game that looks and acts like networking. It’s programmed to behave correctly for educational purposes, but it isn’t the real thing.
Think of GNS3 as a car mechanic’s garage that lets you put real car engines (IOS images) on test benches. You are working with the actual software that runs real devices.
Realism:
In Packet Tracer, you might find that a specific show command is missing. A protocol might behave in a slightly simplified way. It’s “good enough” for its purpose.
In GNS3, if a command works on a physical router, it will work. This is crucial for testing complex scenarios where exact behavior matters.
Performance:
Packet Tracer is optimized to run hundreds of devices on an average laptop because it’s just simulating the logic.
GNS3 runs real, resource-heavy operating systems. Each device you run consumes CPU and RAM, similar to a real device. Running a few routers can easily consume several gigabytes of RAM.
Device Support:
Packet Tracer is a walled garden. You get what Cisco provides.
GNS3 is an open platform. Its functionality is limited only by the images you can obtain and your hardware’s ability to run them. This allows for incredible multi-vendor labs.
Conclusion: Which One Should You Use?
The choice between Packet Tracer and GNS3 is not about which tool is “better.” It is about which is the right tool for your specific needs.
Choose Cisco Packet Tracer if:
You are a beginner starting your networking journey (especially in the Cisco NetAcad).
You are studying for the CCNA.
You want a simple, easy-to-set-up tool for basic labs.
Your computer has limited hardware resources.
Choose GNS3 if:
You are an advanced student preparing for CCNP, CCIE, or other vendor certifications.
You are a network professional needing to test complex configurations in a safe environment before deploying them.
You need to work with a multi-vendor environment (Cisco, Juniper, Linux, etc.).
You require 100% real-world command and behavior accuracy.
You have a powerful computer with plenty of RAM and a strong CPU.
Many network engineers end up using both tools at different stages of their careers. They start with Packet Tracer to grasp the fundamentals. Later, they graduate to GNS3 (or its alternative, EVE-NG) for advanced, production-like practice.

Configuring sub-interfaces on a Cisco router in Packet Tracer facilitates communication between VLANs. It provides segmented networks within a single physical connection. In this guide, we’ll set up a Cisco router (Router0) with sub-interfaces. This will allow it to route traffic between VLANs. We will also assign static IP addresses to client PCs.
Project Plan and Configuration Overview
This setup is common in networks that use VLANs to separate different departments, user groups, or services within an organization. The network will include three VLANs: VLAN Default (VLAN-1), VLAN-2, and VLAN-3. The clients will use static IP addresses to connect to these VLANs.
Router (Router0): Configured with sub-interfaces for each VLAN.
Router Interface Gi0/0: Trunk link connected to Switch0’s Gi0/1.
Switch (Switch0): Configured with VLANs and ports assigned to specific VLANs.
Switch Port Gi0/1: Trunk link connected to Router0’s Gi0/0.
Switch Port Fa0/1: Assigned to VLAN-1 (Default).
Switch Port Fa0/2: Assigned to VLAN-2.
Switch Port Fa0/3: Assigned to VLAN-3.
Clients: PCs with static IP addresses.
PC0: VLAN-1 with IP 172.16.1.x/16
PC1: VLAN-2 with IP 192.168.2.x/24
PC2: VLAN-3 with IP 192.168.3.x/24
Step Configuration Cisco Packet Tracer
Right now, I am starting to configure or create all VLan on the Switch0. I am also setting up port access and port trunk on Switch0.
1. Set Up the Switch (Switch0)
Create VLANs on Switch0:
Access Switch0 and go to the CLI.
Enter global configuration mode: enable configure terminal
Create the VLANs: vlan 1 vlan 2 vlan 3
Exit VLAN configuration mode.
Assign Ports to VLANs:
Configure Fa0/1 for VLAN-1 (Default): interface fa0/1
switchport mode access
switchport access vlan 1
exit
Configure Fa0/2 for VLAN-2: interface fa0/2
switchport mode access
switchport access vlan 2
exit
Configure Fa0/3 for VLAN-3:
interface fa0/3
switchport mode access
switchport access vlan 3
exit
Configure Trunk Port on Gi0/1:
Set Gi0/1 as a trunk port to allow VLAN traffic to the router: interface gi0/1
switchport mode trunk
exit
2. Configure Sub-Interfaces (Router0)
Now we configure on Cisco Router of Packet Tracer with Sub-Interfaces. Note that sub internet we need to configure the router only.
Access Router0 and go to CLI mode:
enable
configure terminal
Configure Sub-Interfaces for Each VLAN:
Sub-Interface for VLAN-1 (Default): interface gigabitEthernet 0/0.1
encapsulation dot1Q 1
ip address 172.16.1.1 255.255.0.0 exit
Sub-Interface for VLAN-2: interface gigabitEthernet 0/0.2
encapsulation dot1Q 2
ip address 192.168.2.1 255.255.255.0
exit
Sub-Interface for VLAN-3:
interface gigabitEthernet 0/0.3
encapsulation dot1Q 3
ip address 192.168.3.1 255.255.255.0
exit
Verify Interface Configuration:
Exit configuration mode and check interface settings: show ip interface brief
3. Configure Static IP Addresses on PCs
PC0 (VLAN-1):
Open PC0, go to Desktop > IP Configuration, and set:
IP Address: 172.16.1.2
Subnet Mask: 255.255.0.0
Default Gateway: 172.16.1.1
PC1 (VLAN-2):
Open PC1, go to Desktop > IP Configuration, and set:
IP Address: 192.168.2.2
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.2.1
PC2 (VLAN-3):
Open PC2, go to Desktop > IP Configuration, and set:
IP Address: 192.168.3.2
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.3.1
4. Test Connectivity Between VLANs
Ping Between PCs:
Open Command Prompt on each PC and ping the router’s sub-interface corresponding to their VLAN:
From PC0, ping 172.16.1.1
From PC1, ping 192.168.2.1
From PC2, ping 192.168.3.1
To test inter-VLAN connectivity, try pinging PCs across VLANs:
From PC0 to PC1’s IP (192.168.2.2)
From PC1 to PC2’s IP (192.168.3.2)
From PC2 to PC0’s IP (172.16.1.2)
Successful pings confirm that the router is routing traffic between VLANs.
We configured sub-interfaces on the router and assigned VLANs on the switch. This setup enabled inter-VLAN communication for PCs with static IP addresses in separate VLANs. This setup shows how VLAN segmentation can work with a single router interface. It is a fundamental skill in network design.

Configuring DHCP on a Cisco router in Packet Tracer is an essential skill for network students. It automates IP address assignment, making network management more efficient. In this guide, we will setup DHCP on a router. This setup will provide automatic IP addresses to client PCs.
These PCs are connected via a switch. Our setup includes a router (Router0) that is configured to act as a DHCP server. A switch (Switch01) provides connectivity, and there are two client PCs (PC0 and PC1). The router will use the 192.168.1.0/24 network to allocate IP addresses.
Let’s dive into the configuration!
Network Setup and Configuration Plan
Router (Router0): This device will be configured to provide DHCP.
Router Interface (Gi0/0): Connected to Switch01 (IP address range 192.168.1.0/24).
Switch (Switch01): Acts as the central device to connect PCs to the router.
Switch Port Gi0/1: Connects to Router0 (Gi0/0).
Switch Port Fa0/1: Connects to PC0.
Switch Port Fa0/2: Connects to PC1.
DHCP Scope: The router will distribute IP addresses from 192.168.1.1 to 192.168.1.254 with a /24 subnet mask.
Step Configuration Cisco Packet Tracer
Connect Devices:
Connect Router0’s Gi0/0 interface to Switch01’s Gi0/1 port using a copper straight-through cable.
Connect PC0 to Switch01’s Fa0/1 port and PC1 to Switch01’s Fa0/2 port.
Configure the Router (Router0):
Select Router0, then go to the CLI tab.
Enter global configuration mode: enable configure terminal Set host name on Router
[content-egg-block template=offers_list_groups]
Configure Interface Gi0/0 on Router0:
Assign an IP address to the Gi0/0 interface in the 192.168.1.0/24 network:
interface gigabitEthernet 0/0
ip address 192.168.1.1 255.255.255.0
no shutdown
exit
Enable DHCP on the Router:
Define the DHCP pool and configure the IP address range:
ip dhcp pool LAN-network
192.168.1.0 255.255.255.0
default-router 192.168.1.1
dns-server 8.8.8.8 exit
Here, we define a DHCP pool named LAN_POOL. The router will assign IP addresses within 192.168.1.0/24 and set 192.168.1.1 as the default gateway, while 8.8.8.8 is configured as the DNS server.
Exclude the Router IP Address from the DHCP Pool (to avoid conflicts):
Exclude 192.168.1.1 to reserve it for the router itself. Now I excluded some IP addresses to use with static devices. The PCs will start from DHCP from 192.168.1.11 Howto-R(config)#ip dhcp excluded-address 192.168.1.1 192.168.1.10
Verify DHCP Configuration:
Exit configuration mode and verify DHCP setup: show ip dhcp pool
show ip dhcp binding
Configure the Clients (PC0 and PC1):
On PC0 and PC1 in Packet Tracer:
Open the Desktop tab.
Select IP Configuration.
Choose DHCP for IP settings.
After a moment, each PC should receive an IP address from the 192.168.1.0/24 range. Verify that PC0 and PC1 have IP addresses within the range, with 192.168.1.1 as the default gateway.
Test Connectivity:
On either PC0 or PC1, go to the Command Prompt in the Desktop tab.
Test connectivity by pinging the router at 192.168.1.1: ping 192.168.1.1
Successful replies confirm that the DHCP configuration is working correctly, and the PCs are receiving IP addresses automatically.
This hands-on example shows how to configure DHCP on a Cisco router in Packet Tracer. It simplifies the process of assigning IP addresses automatically to client devices on a network. DHCP is a valuable tool for simplifying network management, especially in larger networks.
Note: This post, How To Kh, shows only how to configure DHCP on a Cisco Router. It focuses on the Configuration DHCP only. If you want to know clearly with full configuration can visit here with CCNA basics.

Dynamic Host Configuration Protocol (DHCP) is a network management protocol. It automatically assigns IP addresses. It also provides other network settings to devices on a network. Understanding how DHCP works: Dynamic Host Configuration Protocol simplifies the process of connecting devices (like computers, smartphones, printers, etc.). It connects devices to a network by dynamically providing each device with its IP address. This is essential for communication within that network and on the Internet.
How DHCP Works Step-by-Step
The DHCP process has four main steps, often remembered by the acronym DORA. These steps outline how DHCP works: Dynamic Host Configuration Protocol, which includes Discover, Offer, Request, and Acknowledge.
Discover: When a device (often called a “client”) connects to a network, it sends out a DHCP Discover message. This message requests an IP address. It is broadcast to all devices on the local network. It asks any available DHCP server for an IP address.
Offer: A DHCP server on the network receives the Discover message and responds with a DHCP Offer message. This message includes an available IP address for the client. It also includes other configuration settings like the subnet mask, default gateway, and DNS servers.
Request: The client responds by sending a DHCP Request message to the server. This message indicates that it wants to accept the offered IP address.
Acknowledge: The DHCP server responds with a DHCP Acknowledge message, confirming the IP address lease to the client. This acknowledgment also includes a lease duration. It indicates the time the client can use the IP address before needing to renew the lease.
After the acknowledgment, the client has a valid IP address and is ready to communicate on the network. The process of how DHCP works: Dynamic Host Configuration Protocol is fully automated and generally takes only a few seconds.
Key Elements Provided by DHCP
DHCP doesn’t just provide IP addresses; it also delivers several other critical network settings:
Subnet Mask: Defines the network’s range of addresses.
Default Gateway: Specifies the router’s address that sends data outside the local network.
DNS Server: It provides the IP address of the server. This server translates website names to IP addresses. This process allows users to browse the internet.
Example of DHCP in Action
Let’s say a laptop connects to a Wi-Fi network at home. The DHCP server in the router assigns it an IP address of 192.168.0.101 along with a subnet mask (e.g., 255.255.255.0), a default gateway (e.g., 192.168.0.1), and a DNS server (e.g., 8.8.8.8 for Google DNS). This example illustrates DHCP in action and how DHCP works: Dynamic Host Configuration Protocol. This allows the laptop to access the local network and communicate over the internet seamlessly.
Benefits of DHCP
Efficient IP Management: DHCP eliminates the need to manually assign and manage IP addresses, reducing errors and administrative tasks.
Scalability: It supports large networks, as it can automatically allocate IPs to multiple devices without the need for manual configurations.
Flexibility: DHCP leases can expire, which helps in freeing up IP addresses from devices no longer connected to the network.
DHCP is an essential protocol in modern networking, offering a streamlined way to assign IP addresses and network configurations. It helps manage network connections automatically, making it easier to connect devices without needing to configure IP settings manually.
For anyone studying networking, understanding DHCP is a fundamental skill that can help with managing and troubleshooting networks more effectively. By knowing how DHCP works: Dynamic Host Configuration Protocol, you can more effectively manage and troubleshoot networking issues.

In today’s interconnected world, understanding how devices communicate on a network is essential. One of the key protocols that facilitate this communication is DHCP or Dynamic Host Configuration Protocol. DHCP is a network management protocol. It automates the process of configuring devices on IP networks. This allows them to connect and communicate seamlessly.
By automatically assigning IP addresses to devices, DHCP saves time and reduces the chance of errors in manual configurations. This article will explore what DHCP is, how it works, and why it’s important for both home and enterprise networks. Below network structure is the client PC1 gets DHCP from Vlan-10 with by Automatic IP address: 10.10.1.4 Sub Netmask: 255.255.255.0
Suppose you connect your laptop or PC to a Wi-Fi network at school. As soon as your device tries to connect, the network’s DHCP server steps in to assign an IP address. Let’s walk through the process:
Discovery: Your laptop sends out a broadcast message asking for an IP address. This is called a DHCP Discover message.
Offer: The DHCP server on the school network receives the message. It responds by “offering” an available IP address, say, 10.10.1.4. This offer includes other settings like the subnet mask and DNS server. This is called a DHCP Offer message.
Request: Your laptop responds to the offer by requesting that specific IP address. This message is known as a DHCP Request.
Acknowledge: Finally, the DHCP server sends an acknowledgment, confirming that 10.10.1.4 is now assigned to your laptop. The server also sets a “lease time.” This is the length of time your laptop can use this IP address. When the lease time expires, your laptop needs to renew it.
Automatic IP address: 10.10.1.4 Sub Netmask: 255.255.255.0
In this example, 10.10.1.4 is the IP address dynamically assigned by the DHCP server to your device. This automatic process makes it easy to manage IP addresses across many devices on the network without manual setup.
Mastering DHCP is a great way to build foundational knowledge in networking. It is especially beneficial for students interested in IT or computer science. With its ability to simplify network management, understanding DHCP can be a valuable skill for future tech professionals.

A Blast from the Networking Past
The Cisco-Linksys E2000 Advanced Wireless-N Router is a classic device from an era when home broadband was becoming truly high-speed. At that time, the demand for stable wireless connectivity was exploding. While it carries the reputable Cisco-Linksys branding, it’s crucial to evaluate it through the lens of modern needs and technology. This review will assess its features and performance. More importantly, it will evaluate its relevance in today’s world of 4K streaming, gaming, and smart homes.
Ports: 4 x Gigabit Ethernet LAN, 1 x Gigabit Ethernet WAN, 1 x USB 2.0
Antennas: 3 internal antennas
The Good (For Its Time):
Dual-Band Capability: This was the E2000’s standout feature. The 5 GHz band provides a cleaner signal for devices closer to the router. It is less congested, offering a significant advantage over single-band routers of its day.
Gigabit Ethernet Ports: The inclusion of full Gigabit ports for wired connections was excellent. This allows wired devices like gaming consoles, desktop PCs, or NAS drives to achieve maximum wired speeds. They can still reach these speeds even with today’s internet plans.
Stable & Reliable Performance: The E2000 was renowned for basic tasks. It performed well in web browsing. It was suitable for email and standard-definition video streaming on a handful of devices. It was known for its Cisco-driven reliability. It also had stable firmware.
USB Port (For Basic Sharing): The USB 2.0 port allows for very basic network storage or printer sharing, though its performance is slow by modern standards.
The Limitations (By Modern Standards):
Outdated Wi-Fi Standard (Wi-Fi 4): This is its biggest drawback. Modern routers use Wi-Fi 5 (802.11ac) or Wi-Fi 6 (802.11ax), which offer far faster speeds, better range, and significantly improved ability to handle multiple devices simultaneously. The E2000’s 300 Mbps theoretical speed is insufficient. Today’s internet plans often exceed 500 Mbps or even 1 Gbps.
Limited Range and Coverage: It only has internal antennas and older wireless technology. Its range and ability to penetrate walls are inferior to modern routers. Modern routers have high-gain external antennas and advanced beamforming technology.
No Modern Features: It lacks any of the advancements we now take for granted:
No MU-MIMO: Cannot communicate with multiple devices at once.
No Mesh Capability: Cannot be used as part of a whole-home mesh system for seamless roaming.
Outdated Software/Security: It has not received firmware updates in years, potentially leaving your network vulnerable to known security flaws. The USB port is too slow for media streaming.
Reliable Workhorse, But Time Has Moved On
The Cisco-Linksys E2000 was a fantastic router in its prime. It represented a solid step into the world of dual-band networking for many households. It is built with quality components that, for some, are still functioning today. Its wired Gigabit ports remain a valid asset.
However, technology has advanced exponentially. The demands of the modern connected home have far surpassed what the E2000 was designed to handle. This includes its plethora of smartphones, tablets, smart TVs, security cameras, and gaming consoles.
Should You Buy It?
My suggestion is: only in one very specific scenario.
Do NOT buy it if you need a primary router for your main home network. Do not buy it if you have a fast internet plan (over 100 Mbps). Do not buy it if you have more than a few Wi-Fi devices.
You could consider it if you find it for a very low price (under $15). It is advisable if you need a secondary, wired-only access point. You would disable its Wi-Fi and use its Gigabit ports to connect wired devices in another room. Using its outdated wireless functionality as your main network would be a significant bottleneck and a potential security risk.
For virtually everyone else, I strongly suggest investing in a modern Wi-Fi 5 or Wi-Fi 6 router. Consider brands like TP-Link, ASUS, or Netgear. These will provide the speed, range, security, and device-handling capabilities that are essential for a reliable and future-proof home network. Your online experience will be dramatically better.
Configuring a Cisco network with routers, switches, VLANs, and DHCP can be challenging yet rewarding for network administrators. In this project, we set up multiple VLANs on a router. These VLANs segment different types of network traffic. This approach ensures efficient communication across devices. We used trunking to allow multiple VLANs to communicate between switches.
We also configured DHCP to automatically assign IP addresses to devices. With VLAN 99 dedicated to remote management, network administrators can securely manage network devices via SSH, enhancing security and accessibility.

Could you repeat similar steps for Switch 3, Switch 4, and Switch 5 with the appropriate VLANs and access ports? This procedure is crucial for understanding how to configure Cisco routers and switches effectively in a complex network setting.
Step 4: Configure SSH on Switches and Router
Enable SSH on the router and main switch for remote access via VLAN 99.
Set hostname, domain name, and generate crypto keys.
Configure SSH user and enable vty lines for SSH access. Example configuration:
Howtokh-R#
Howtokh-R(config)#username admin secret cisco
Howtokh-R(config)#enable secret cisco
Howtokh-R(config)# line vty 0 4
Howtokh-R(config-line)# login local
Howtokh-R(config-line)# transport input ssh
Howtokh-R(config)#ip ssh version 2
Howtokh-R(config)# ip domain-name howtokh.com
Howtokh-R(config)# crypto key generate rsa
Note: bit rate: 512, 1024,...
Howtokh-R(config)# line con 0
Howtokh-R(config-line)# password cisco
Howtokh-R(config-line)# login local
Howtokh-R(config)# services password-encryption
Howtokh-R(config)# do wr
Step 5: Test Remote to Router for Connectivity
Ensure PCs are set to receive IP addresses via DHCP.
Verify IP Configuration on each VLAN by using ping commands to ensure connectivity across VLANs and access to the router.
Test SSH access to confirm that SSH can reach devices using VLAN 99.
Remote from Laptop to router with the command: ssh -l admin 10.99.9.1
This setup should enable inter-VLAN routing, and remote management via SSH on VLAN 99. Feel free to let me know if you need additional configurations or troubleshooting tips!
Step 6: Test Remote to Switch-1 for Connectivity
Remote from Laptop to Switch 1 with remote IP address as command: ssh -l admin 10.99.9.2
For students interested in mastering Cisco networking, diving into topics like VLANs, trunking, DHCP configuration, and SSH setup is fundamental. Start by practicing on simulators like Cisco Packet Tracer or GNS3, allowing you to experiment safely. Additionally, consider exploring:
Switching and Routing Protocols like OSPF and EIGRP to improve network performance.
Network Security basics, including secure remote access methods and ACLs (Access Control Lists).
Building a solid understanding of these Cisco concepts is essential. This includes learning how to configure a Cisco router and switch. It will prepare you well for real-world network management and troubleshooting. Happy learning!
To configure a Cisco Packet Tracer project where a router connects to a switch with two VLANs (VLAN10 and VLAN20), and each VLAN has its subnet, follow these steps:
Network Design:
Router:
Interface: gi0/0 connected to the switch.
Sub-interfaces configured for each VLAN with IP addresses for inter-VLAN routing.
Switch:
VLAN10 and VLAN20 created.
Ports assigned to each VLAN for devices on each subnet.
On the router’s gi0/0 interface, create sub-interfaces for VLAN10 and VLAN20. Assign IP addresses to the sub-interfaces. Encapsulate each sub-interface with the appropriate VLAN ID.
Howtokh-R(config)# interface gi0/0.10
Howtokh-R(config-subif)# encapsulation dot1Q 10
Howtokh-R(config-subif)# ip address 10.1.1.1 255.255.255.0
Howtokh-R(config-subif)#description Vlan10
Howtokh-R(config-subif)# do wr
Howtokh-R(config-subif)# exit
Howtokh-R(config)# interface gi0/0.20
Howtokh-R(config-subif)# encapsulation dot1Q 20
Howtokh-R(config-subif)# ip address 192.168.0.1 255.255.255.0
Howtokh-R(config-subif)#description Vlan20
Howtokh-R(config-subif)# do wr
Howtokh-R(config-subif)# exit
Enable the Router Interface:
Howtokh-R(config)# interface gi0/0
Howtokh-R(config-if)# no shutdown
Howtokh-R(config-if)# exit
3. Configure Static IP for Clients
Connect a PC to fa0/1 for VLAN10 and another PC to fa0/2 for VLAN20.
PC in VLAN10: Assign IP Address to PC
IP Address: 10.1.1.X (e.g., 10.1.1.10)
Subnet Mask: 255.255.255.0
Default Gateway: 10.1.1.1
[content-egg-block template=offers_logo_shipping]
PC in VLAN20:
For the PC2 in VLAN20, you can follow steps 1 in VLAN10
IP Address: 192.168.0.X (e.g., 192.168.0.10)
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.0.1
4. Test Connectivity
Use the ping command from each PC to test connectivity with its VLAN gateway.
Ensure PCs in VLAN10 and VLAN20 cannot communicate directly. They should reach the router’s respective sub-interface IP addresses for inter-VLAN routing, if configured.
After assigning the IP Address you should ping test to make sure it working or not
This setup enables clients in VLAN10 and VLAN20 to access their designated networks with static IP addresses. You can now ping as well. Learn more…
Cisco CCNA course duration
For most people, anywhere from 3 to 6 months of dedicated study is realistic. This timeframe allows them to go from zero knowledge to being prepared for the CCNA exam.
Fast Learner (with some IT experience): ~2-3 months
Dedicated Beginner (no IT experience): ~4-6 months
Studying Part-Time (busy schedule): 6+ months
Factors That Influence Your Timeline
Prior Experience:
No IT background: You’ll need to learn fundamental concepts from scratch, which will take longer. Plan for the 5-6 month range.
Some IT/Networking knowledge: If you already understand basic concepts like IP addresses, DHCP, or DNS, you have a head start. You might fit into the 3-4 month range.
Experienced but uncertified: If you’ve been working with networks for years, you might just need the credential. In that case, you could be ready in 1-2 months. You only need to brush up on the specifics.
Study Time Commitment:
Full-Time Student: If you can treat studying like a full-time job, plan to study 6-8 hours a day. This approach allows you to compress the timeline significantly.
Working Professional: This is the most common scenario. If you can consistently dedicate 1.5 – 2 hours on weekdays. Dedicate 3-4 hours on weekends. Total approximately 15 hours per week. Then you can achieve the 4-5 month range.
Learning Method:
Self-Study (Video Courses, Books): This is the most flexible and common path. The pace is entirely up to you.
Bootcamps: Intensive, instructor-led bootcamps can cover all the material in 1-2 weeks. However, they require full-time attendance. They are also very expensive. They are best for quickly consolidating knowledge, not necessarily for learning from zero.
Formal Education: A college course might spread this material over a full semester (3-4 months).
Realistic 5-Month Study Plan
This plan assumes you’re studying 15-20 hours per week.
Month 1: Networking Fundamentals
Topics: TCP/IP and OSI models, IPv4 and IPv6 addressing, subnetting, network media (cables, Wi-Fi).
Focus:Master subnetting. This is the most critical foundational skill. Don’t move on until you can do it quickly.
Month 2: Network Access & IP Connectivity

Crucial Advice for Success
Get Hands-On: Reading and watching videos is not enough. You must lab. Cisco Packet Tracer is free and perfect for the CCNA. Build networks, break them, and fix them.
Use Multiple Resources: Don’t rely on just one book or video series. Different instructors explain things in different ways. Popular choices include:
Video Courses: Neil Anderson (CBT Nuggets), Jeremy’s IT Lab (free on YouTube), Keith Barker.
Books: Official Cert Guide by Wendell Odom.
Practice Exams: Boson ExSim is considered the gold standard.
Understand, Don’t Memorize: The CCNA exam tests your ability to apply concepts, not just recall facts. If you understand the “why,” you can answer any question.
Set a goal of 4-6 months. Create a consistent study schedule. Get plenty of hands-on practice. You will be well on your way to earning your CCNA. Good luck

Overall Summary CISCO DESIGNED Business PoE
The Cisco CBS220-24P-4G is a well-rounded, “smart” managed PoE switch. It is designed for small to medium-sized businesses (SMBs) that need more control than an unmanaged switch offers. However, they don’t require the full complexity of an enterprise-grade device. It hits a sweet spot between power, features, and ease of use.
Key Advantages (The Pros)
Power over Ethernet (PoE): This is a major selling point.
24 PoE Ports: You can power a large number of devices directly from the switch. These include VoIP phones, wireless access points, and security cameras. Wi-Fi 6/6E APs often need PoE+. You can even power some monitors.
195W Total Budget: This is adequate for a typical SMB deployment. However, you must do some power planning. For example, if you have 24 devices each drawing the max for standard PoE (15.4W), you’d need ~370W. You must ensure your high-power devices, like PTZ cameras, don’t exceed the 195W limit. This also applies to certain APs that use PoE+.
Ease of Use & Management:
Cisco Business Dashboard: This is a huge pro for multi-device setups. You can manage a network of these switches. It also includes other Cisco Business devices, from a single, simple cloud-based interface. This simplifies setup, monitoring, and firmware updates dramatically.
Mobile App & On-Box UI: Offers multiple ways to configure the switch. This feature makes it accessible for users with different skill levels.
Security Features: It includes robust security for its class:
802.1X: This is a enterprise-grade feature. It allows you to authenticate devices and users before granting them network access. This is crucial for securing networks with personal devices or guest access.
ACLs (Access Control Lists): Let you create rules to control traffic flow (e.g., block a specific device from accessing the accounting server).
DoS Protection: Helps keep the network running during a malicious attack.
Design and Form Factor:
Compact and Elegant: It’s designed to be placed on a shelf or in an open area. It is not just locked in a hot, noisy wiring closet. This is perfect for retail stores, classrooms, or open-plan offices.
Fanless Operation (in this model): This is a critical feature. No moving parts means it is completely silent, which is essential for any environment where people are working.
Reliability and Support:
Cisco Brand: You’re buying from a known leader in networking, which generally means build quality and reliability.
3-Year Warranty: A strong warranty that provides peace of mind.
Potential Limitations (The Cons)
PoE Power Budget: As mentioned, 195W is on the lower side for a 24-port PoE switch. It’s a constraint you must design around. If you plan to run many power-hungry devices (e.g., 10+ PoE+ devices drawing 30W each), you will quickly run out of power. Calculate your power requirements carefully before buying.
“Smart” vs. “Managed”: This is a “smart” switch. This means it has a web interface and good features, but it lacks some deeper capabilities of a fully managed switch (like Cisco’s Catalyst line), such as:
Advanced routing protocols (it has static routing only).
More granular traffic shaping and advanced SNMP features.
CLI (Command Line Interface) access is limited compared to enterprise models.
The 1G SFP Uplinks: The four SFP ports are 1 Gigabit. This is fine for most SMB applications. However, modern higher-end switches are moving toward 10G SFP+ uplinks for faster aggregation and backbone connections. If you have a very fast internal network, you might face a bottleneck in the future. The same applies if you have a multi-gigabit internet connection.
Who Is This Switch Ideal For?
Small to Medium Businesses: Offices, clinics, law firms that need reliable wired connectivity and PoE.
Schools & Classrooms: To power VoIP phones, APs, and teacher computers quietly.
Retail Stores: For point-of-sale systems, cameras, and Wi-Fi, with a clean look.
Light-to-Moderate PoE Deployments: A mix of IP phones, a handful of access points, and a few security cameras.
Who Should Consider Something Else?
High-PoE Demand Environments: If you need to power more than ~6-8 high-power PoE+ devices, get a switch with a 370W+ power budget. Make sure the switch meets the power requirements. This includes devices like advanced PTZ cameras, thin clients, or extensive AP setups.
Large Enterprises: Networks that require advanced features need a fully managed Catalyst switch. Those requiring CLI-heavy management also benefit from it. Integration with complex network management systems would be better served by this type of switch.
Future-Proofing for 10G: Consider your need for 10G uplinks to your server or core switch. Think about this requirement within the device’s lifespan. Look for a model with SFP+ ports.
