  • Improve network visibility with CX switches

    With the recent increase in the complexity of IT infrastructure, more and more devices are being connected to networks. For network operators, the biggest challenge is determining which equipment is connected where and what actions it performs. For this reason, many observability solutions are being introduced to provide visibility and visualization. Today, even without implementing and deploying a separate solution, visibility into network traffic…

  • What is HPE's direction in Ultra Ethernet (UEC)?

    The Ultra Ethernet Consortium (UEC), officially launched in July 2023, was formed to develop Ethernet specifications that enhance AI and High Performance Computing (HPC) environments with a new level of performance, scalability, and interoperability. Hewlett Packard Enterprise (HPE) is one of the original founders of the UEC and contributed a significant portion of the foundational IP included in UEC Specification Revision 1.0. Today, UEC IT…

  • Automate Operations with AOS-CX NAE Lite

    The AOS-CX switch is equipped with a proprietary analytics engine called the Network Analytics Engine (NAE). The NAE is a unique built-in analytics framework used for network assurance and troubleshooting. The NAE Agent is provided by HPE Aruba and is essentially a Python script for monitoring switch resources and protocol status. However, in this post, we will discuss a topic that does not require knowledge of scripts…

  • AOS-CX Security Settings Guide (2)

    In the previous post, we examined the physical security and Management Plane security of the AOS-CX switch. This time, we will discuss the security of the Control Plane of the AOS-CX switch. The content of both the previous and current posts is based on official information found on the HPE website. Go to AOS-CX 10.15 Hardening Guide (All Switch Series) Control Plane Security Control…

  • AOS-CX Security Settings Guide (1)

    Awareness of network security is growing. Traditional network security mostly involved configuring IP address-based firewalls. However, as numerous applications and systems are now connected to networks, the security of network switches is becoming increasingly important. As networks become more complex and interconnected, interest in the security settings of each switch is rising…

  • Configuring RoCE in AOS-CX (2) – Hands-on

    In the previous post, we looked into what RoCE is and why it is necessary. Now, let's explore how to implement RoCE on AOS-CX switches. To configure RoCEv2 on HPE Aruba Networking CX switches, the following items are required. As of March 2025, the supported switch series are the CX 10000, 9300, 8400, 8360, 8325, and 8100. RoCE…

  • The Importance of Precision Timing Demonstrated at MWC 2025

    MWC (Mobile World Congress) 2025 was held in Barcelona again this year. At the event, HPE accelerated networking innovation while launching new services for telecommunications carriers and enterprise customers. Through this, they introduced new solutions to advance their long-standing vision of supporting the connection of the network edge to the cloud. At MWC25, HPE Aruba Networking stated that AI is what telecommunications carriers can offer to their customers…

  • IPv6-ready switches: HPE Aruba Networking switches

    Veteran network administrators likely remember the simple network days of the past, when there were few devices required for internet access and connections were static. As the number of network devices increased, Internet Protocol v4 (IPv4) was created to enable management, routing, and security by tagging them with unique identifiers (i.e., addresses). IPv4 provides 32 bits of storage space and scalability…
