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...

What is a SWITCH ?



A network Switch is a networking device that connects devices together, these devices could be, computers, printers, other switches, routers or even firewalls and servers..

It uses a technique that is called packet switching to receive, process and forward data to the destination

Unlike less advanced network HUBS a network switch forwards data only to one or multiple devices that need to receive it, rather than broadcasting the data out of each of its interfaces.

A network switch contains multiple ports and is considered as a network bridge that uses Hardware addresses or MAC addresses, to process and forward data at the link layer from layer 2 of the OSI model

Some switches can also process data at the network layer which is LAYER 3, and that happens by additionally incorporating routing functionality that most commonly uses IP address to perform packet forwarding. This kind of switches is known as LAYER 3 switches.


A Switch is a device that connects other devices, multiple data cables are plugged into a switch to enable communication between different network devices.

Switches manage data flow across a network by sending a received network packet only to one or more devices on which the packet is destined.
Each network device connected to an adapter can be identified by its network address, allowing the switch to regulate traffic flow, which increases the security and efficiency of the network.

A switch is smarter than a HUB, which simply retransmits packets out of every port, which makes a broadcast domain that can affect the network stability. A HUB is unable to distinguish different recipients.
Also, Switches may operate at one or more layers of the OSI model including the data link and network layers.

There are too many manufacturers of switches in networking:

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...
