Basic Campus Quality of Service (QoS) design

Introduction Quality of Service (QoS) is the ability to provide different priorities to different applications, users, or data flows, or to guarantee a certain level of performance to a data flow. QoS processes apply to traffic that flows through Ethernet ports and control planes. These processes can modify data fields (Class of Service (CoS) or Differentiated Services Code Point (DSCP)) or assign data streams to traffic classes for prioritised handling. In this document we will be implementing a basic enterprise QoS model. Consider the following topology for the following examples:   What do we want to achieve In this example,...

Setting up EVE-NG, CloudVision Portal and vEOS

Introduction EVE-NG is a client-less multivendor network emulation software that enables network and security professionals to build out network topologies and simulate networking environments. Using EVE-NG, Arista vEOS and Arista CloudVision, it is possible to simulate from start to end, connecting and provisioning a datacenter network, test scripting for CloudVision and finally test your EVPN Spine-Leaf configuration. This guide explains how to start an EVE-NG environment (either using the OVF image provided on the EVE-NG site, or by doing a bare-metal install), adding the vEOS and CloudVision images to EVE-NG and connecting the switches in a Leaf-Spine topology. The vEOS...
