Distributed VXLAN gateways can be configured to address problems that occur in legacy centralized VXLAN gateway networking, for example, forwarding paths are not optimal, and the ARP entry specification is a bottleneck. On the network shown in the figure below, an enterprise has VMs deployed in different data centers. VM1 on Server1 belongs to VLAN […]

Assign VLANs Based on IP Subnets in the Huawei Switch
A data center network has multiple services, including office services, production services, and disaster recovery services. Each service uses a unique IP subnet. To facilitate management, packets of the same service must be transmitted in the same VLAN, and packets of different services be transmitted in different VLANs. In the figure below, the switch connects to […]
Integration 6 Wind Router with Grafana
This topic will cover how to integrate a 6Wind router (either Physical or Virtual) with Grafana, a monitoring platform that shows runtime information on a web-based graphical interface. To do so, we should prepare at least 1 Ubuntu 22.04 (Virtual or physical) that can connect to the 6Wind IP Management access to install the Grafana […]
SLX-OS (Chassis product version): FPGA Version mismatch after reboot first time or update firmware
Whenever we install the SLX device for the first time, the module’s application FPGA version can be mismatched with the hardware FPGA version. In SLX 9850 (chassis device version) we can check with this command: In SLX 9540 (Compact device version) we can check with this command: A version mismatch between FPGA applications and hardware […]
6wind Ansible NETCONF Automation
Ansible supports configuring remote hosts using NETCONF (instead of the default SSH connection along with Linux shell commands). This guide explains how to leverage Ansible to configure multiple Virtual Service Router instances. Dependencies This guide assumes that you have two (or more) Virtual Service Router instances that are booted and accessible on the network (NETCONF […]
RDMA, ROCE test in Network with MPI Tools
In the need for AI network infrastructure, an ROCE test in the network fabric is needed to ensure that the ongoing traffic is always in the low latency condition and get the best high bandwidth in the future. In this section, we talk about how to test the ROCE network in the Kubernetes cluster premise. […]
Enabling root account on SLX OS
By default, the root account on the virtual machine (VM) is disabled. To log into root, you can log into the SLX-OS CLI and enable the root account from global configuration mode by using this command. In rare cases, SLX-OS CLI may not be available to enable the root account. NoteThe default password for the root account on the VM […]
Dragonfly and Dragonfly+ Topology
In this section, we talk about Dragonfly and Dragonfly+ topology. The Dragonfly network topology is a high-performance interconnection network commonly used in large-scale computing systems like supercomputers and data centers. It is designed to provide low latency, high bandwidth, and high fault tolerance for communication between computing nodes. In a Dragonfly network, the system is […]
Create user ssh on Huawei Switch
In Huawei Switch by default, no ssh user is created. The ssh user command creates an SSH user. The undo ssh user command deletes an SSH user. You can create a user using either of the following methods: By default, no authentication mode is configured for an SSH user. The ssh user authentication-type command configures the authentication mode for an SSH […]
