Image
  Automating VLAN Creation on Cisco Devices with Ansible Ansible is a powerful automation tool that simplifies network management tasks, including creating VLANs on Cisco devices. For beginners, this guide will walk you through automating VLAN creation step-by-step, from setting up Ansible to deploying VLAN configurations. What is a VLAN? A VLAN (Virtual Local Area Network) is a logical group of devices within a network that can communicate as if they were on the same physical network, regardless of their physical location. VLANs improve network efficiency and security by segmenting traffic. Why Use Ansible for VLAN Automation? Consistency: Avoid manual configuration errors. Efficiency: Configure multiple devices in seconds. Scalability: Manage large-scale networks easily. Flexibility: Supports various Cisco devices and integrates with other tools. Prerequisites Cisco Device Configuration: Ensure your Cisco devices support SSH and are configured to allow Ans...

  • Troubleshooting network issues.
  • Optimizing network performance.

2. Obtain the Necessary Education

High School Preparation

Start by focusing on subjects like mathematics, computer science, and physics in high school to build a strong foundation.

Higher Education Options

  • Bachelor’s Degree: A degree in Computer Science, Information Technology, or a related field is often preferred. Key courses include networking, operating systems, and cybersecurity.
  • Associate’s Degree or Certifications: For those seeking a quicker path, an associate’s degree combined with certifications can also open doors.

3. Gain Hands-On Experience

Lab Practice

Use networking simulators like Cisco Packet Tracer or GNS3 to practice configuring networks in a virtual environment.

Internships and Entry-Level Roles

Seek internships or entry-level IT positions such as a Network Support Technician or Help Desk Support. These roles provide exposure to real-world networking tasks.

4. Earn Networking Certifications

Certifications are a cornerstone of a network engineer’s career, validating your skills and knowledge. Some of the most sought-after certifications include:

  • Cisco Certified Network Associate (CCNA): Covers fundamental networking concepts and is often the first step for aspiring engineers.
  • CompTIA Network+: A vendor-neutral certification focusing on basic networking knowledge.
  • Juniper Networks Certified Associate (JNCIA): Ideal for those working with Juniper devices.
  • Cisco Certified Network Professional (CCNP): A more advanced certification for experienced professionals.
  • Certified Information Systems Security Professional (CISSP): For engineers focusing on network security.

5. Develop Key Skills

To succeed as a network engineer, you’ll need a mix of technical and soft skills:

Technical Skills:

  • Proficiency in networking protocols (e.g., TCP/IP, BGP, OSPF).
  • Knowledge of network hardware (routers, switches, firewalls).
  • Familiarity with operating systems like Linux and Windows Server.
  • Understanding of cloud networking (AWS, Azure).
  • Experience with network monitoring tools.

Soft Skills:

  • Problem-solving abilities.
  • Communication skills for interacting with teams and clients.
  • Attention to detail.
  • Time management.

6. Stay Updated with Industry Trends

Networking technology evolves rapidly, making continuous learning essential. Keep up with trends such as:

  • Software-Defined Networking (SDN).
  • Network automation and scripting (e.g., Python, Ansible).
  • Cloud computing and hybrid networks.
  • Cybersecurity advancements.

Attend industry conferences, join online forums, and subscribe to networking blogs to stay informed.

7. Pursue Advanced Opportunities

As you gain experience, you can specialize in areas like:

  • Network Security: Focus on protecting networks from cyber threats.
  • Wireless Networking: Design and implement Wi-Fi networks.
  • Cloud Networking: Manage virtual networks in cloud environments.
  • VoIP and Collaboration Tools: Work with voice and video communication systems.

Advanced certifications like CCIE (Cisco Certified Internetwork Expert) or cloud certifications (AWS Certified Advanced Networking) can further boost your career.

8. Network and Build a Professional Profile

  • LinkedIn Presence: Create a detailed LinkedIn profile highlighting your skills and certifications.
  • Networking Communities: Join local or online IT groups to connect with professionals.
  • Portfolio: Showcase projects or case studies you’ve worked on to demonstrate your expertise.

9. Apply for Network Engineering Jobs

When you feel confident in your skills and experience, start applying for network engineering roles. Tailor your resume to highlight relevant skills, certifications, and accomplishments. Prepare for interviews by reviewing networking concepts and common troubleshooting scenarios.

Conclusion

Becoming a network engineer requires dedication, continuous learning, and practical experience. By following these steps and staying committed to your goals, you can build a successful career in this dynamic and rewarding field. Whether you start with formal education or certifications, the journey to becoming a network engineer is as fulfilling as the destination.

Network Access Control NAC | IT NETWORKS

Network Access Control NAC It's something that controls access to the network. And at its simplest level, this is what NAC does.  But if that's all that it was, then it wouldn't be fundamentally different from a network authentication and authorization server. Traditional authentication to the network follows the IEEE 802.1X standard that provided an authentication method to devices wishing to join a Local Area Network (LAN) or wireless LAN. 802.1X Wireless/Wired Authentication The mechanism was a port-based network access control which used agents, the software running on client devices that provide credentials to the authenticator to control access to the network. Another means to control access to a public network such as one serving a coffee shop or in a hotel, is a captive portal. If you've ever connected to a network in an airport, hotel, or coffee shop, you might recall interacting with a web page, sometimes agreeing t...

1- Definition   DMVPN is a technology that's used in secure networks exchanging data between them without needing to redirect traffic through a  headquarter  server  or router . Dynamic Multipoint VPN ( DMVPN ) is a Cisco IOS Software solution for building reliable IPsec Virtual Private Networks (VPN). DMVPN basically is a centralized architecture that provides easier management and implementation for deployments that need very specific access controls, authorizations and restrictions for diverse branches, users, applications and partners. DMVPN + IPSEC 2- Benefits DMVPN provides the ability to create dynamic VPNs without configuring static tunnels between remote peers, including Internet Protocol (IP), IPSEC and Key Management Protocol (ISAKMP peers).   DMVPN is designed  to make HUB-AND-SPOKE   topology  by statically configuring the hub IP address on the spokes, no other changes are needed ...

Issues with CISCO WIRELESS Controller (And resolution) | IT NETWORKS

On Cisco Wireless controller 5520, The Access POINTS try to join the Controller by bringing up a connection through the CAPWAP Tunnel, you can see these attempts through the AP log itself. The problem is that the DHCP server when trying to serve IP Addresses it shows the error BAD_ADDRESS in front of each IP assigned. So I Took a single access point, started debugging it, after that, I noticed that the CAPWAP connection was empty of errors BUT!! it was trying to resolve this name  CISCO-CAPWAP-CONTROLLER This resolution is made with DNS protocol, of course, I honestly wasn't so sure of what I was doing, so I added a new entry in my DNS server and it's corresponding IP was the Controller's after that magically all the Access Points where UP and showed UP on my controller. The controller I'm working with is the CISCO WIRELESS CONTROLLER 5520 Model:  AIR-CT5520-K9 Software Version:  8.3.150.0 Image of the controller Learn...
