VXLAN On Arista AP

Overview VXLAN is a Layer 2 technology that helps you to create a virtual Layer 2 network (overlay network) on top of a physical Layer 3 network (underlay network), enabling you to use Layer 3 features of the underlying network, which cannot be achieved using 802.1q VLANs. Each VXLAN tunnel is identified by the VXLAN segment ID or VXLAN Network Identifier (VNI) which is 24 bits, which enables you to create up to 16 million isolated networks. This overcomes the limitation of VLANs, which have a 12 bit VLAN ID, allowing a maximum of 4,094 isolated networks. Arista WiFi Access...

RF Transmit Power configuration enhancements

Description The transmit power configured on UI is now treated as EIRP (Equivalent Isotropically Radiated Power) instead of radio output power. EIRP is the effective power emitted by the AP in the direction of maxima of radiation pattern and is equal to the sum of Radio Transmit power and antenna gain. UI configuration for External Antennas has been introduced. It applies only to the APs with external antennas. APs with internal antennas would take default values (refer to datasheet for details on antenna gain values). Wireless Manager UI Configuration Tx power and External antenna gain values can be configured from...

Using CloudVision Portal to Manage Arista AnyCloud

Introduction There are many advantages to using Arista’s vEOS Router and CloudVision Portal (CVP) in hybrid cloud environments. Among those advantages are: Arista EOS is a proven and stable network operating system used in some of the largest networks in the world. The same EOS that runs on our physical switches also runs in the public cloud. CloudVision Portal provides a common management model for network devices whether running in a customer’s private data center or in public cloud environments. CloudVision Portal provides turn-key automation and real-time telemetry across private and public cloud environments. One of the primary challenges to...

ClearPass TACACS+ Authorization with CVP

ClearPass TACACS+ Authorization with CVP Introduction The purpose of this article is to learn how to correctly set up the TACACS+ service in Aruba ClearPass in order to successfully authenticate on the CVP GUI as a network admin. Our goal is to configure ClearPass Policy Manager [CPPM] to send us the cvp-roles=network-admin attribute in the TACACS+ Authorization reply packet. By default this does not happen, because cvp-roles is a custom attribute that has to be added to the TACACS+ dictionary on any type of TACACS+ implementation. Without this, the default role of network-operator will be allocated to the user, that...

CloudVision Portal RESTful API Client

Arista Cloudvision® Portal (CVP) provides a central point of management for Arista network switches through shared snippets of configuration (configlets) enabling Network Engineers to provision the network more consistently and efficiently. While CVP highlights a graphical user interface for configuration and management of devices, it also includes a full-featured RESTful API that provides all of the same functionality available via the GUI which can be used to automate workflows and integrate with other tools. CVPRAC is a wrapper client for CVP’s RESTful APIs which greatly simplifies usage of the API and more elegantly handles the connections to the CVP nodes....

CVP APIs: A Non-Programmer’s Guide

1. What are CVP APIs? Most CloudVision Portal (CVP) users are familiar with the web user interface (UI) that facilitates network provisioning, inventory management, tasks management, change control and so on.  CVP application programming interfaces (APIs) offer an alternative means of realizing the same functionality.  The key difference is that, with the CVP APIs, the functionality is realized over a programmatic interface (i.e typically by a piece of software communicating with another piece of software) rather than by a user navigating over a web page and clicking and/or typing.  Figure 1 shows a simplified example of these two methods of...
