  • [ACSA Training #15] AOS-CX CLI Access

    There are several ways to connect to an Aruba CX switch. One of them is likely connecting via the console port. When initially configuring a switch, OOBM (Out-of-Band Management) is typically used through the console port. This special console port is installed on all switch models and types to facilitate configuration, troubleshooting, and management. Of course, the switch…

  • [ACSA Training #14] AOS-CX Architecture

    I previously explained the AOS-CX switch while describing the Aruba switch portfolio. Today, I would like to explain the architecture of the AOS-CX operating system and the switch. AOS-CX Software Architecture: As I mentioned, the AOS-CX switch is equipped with a cloud-native operating system. Since this is a modern database-based network operating system that automates and simplifies many important and complex network tasks…

  • [ACSA Training #5] TCP/IP Stack

    The Internet Protocol Suite is a conceptual model and communication protocol used in the Internet and computing networks. Because the basic protocols of this suite are TCP and IP, it is commonly known as the TCP/IP Stack. This model provides end-to-end data communication. It specifies methods for data packetization, addressing, transmission, routing, and reception. The TCP/IP model is also compared to the OSI 7-layer model…

  • [ACSA Training #4] Types of Traffic

    Today, I would like to learn about the types of traffic. Computer communication can be classified into three categories: Unicast, Multicast, and Broadcast. Unicast represents one-to-one communication (one transmitter and one receiver). To give a simple example, let's assume there are several students in a classroom. A teacher stands at the classroom door and delivers a message by calling out the name of a specific student, let's call A. This…

  • [ACSA Training #2] OSI 7 Layers

    As computers rapidly advanced in the mid-1980s, all manufacturers attempted to implement their own proprietary communication protocols. As a result, compatibility issues arose between products from different manufacturers, leading to unreliable communication. To resolve this, the International Organization for Standardization (ISO) proposed the OSI (The Open Systems Interconnection) model, a standard communication model for computing devices… .

  • [ACSA Education #1] Network Basics

    Today, shall we start by briefly looking into networks? Before we do that, I think we need to understand what communication is. In English, communication is called "Communication." In other words, it means communicating with one another. People conveying their intentions and exchanging information with one another—that is what communication means. The same applies to machines. Different computers exchanging data—that is what computers...

  • Aruba Switch Portfolio

    As mentioned in the previous post, I stated that Aruba possesses three switch lineups. ComwareOS: A lineup continuing from the existing 3Com switches. ArubaOS: A lineup continuing from the existing HP ProCurve switches. ArubaOS-CX: A wired switch lineup focused on edge networks, newly launched following the merger of Aruba and HPE. Aruba continues with these three lineups…

  • Aruba's Portfolio (1)

    Following the Aruba ESP from last time, this time we will take a look at what other Aruba products are available. In the last post, I mentioned that Aruba develops and releases products to improve connectivity and user experience at the edge. Aruba offers not only wired and wireless network products for connectivity but also various solutions designed to enhance the user experience. So, let’s…
