CloudVision and IDE

Is there a way to use a Editor/IDE such as Sublime, PyCharm to Modify and/or deploy Configlets to CVP? I am currently using the Configlet Web Interface and my Configlets are getting bigger. I’d like to try to use an Editor/IDE to edit my Configlets. If you are using an any IDE for CVP Configlets I’d like to hear about your workflow. If you transfer Configlets to CVP via SSH, SFTP or other methods I’d be interested in how you accomplish this. Thanks in advance, Neal

Configuring Traffic Flows using sFlow in CVP (Cloudvision Portal) 2019.1.x

Introduction Many users rely on 3rd party flow tools to enable greater visibility into the network and generate alerts when irregular flows have been detected.  However, with the growing number of tools being used to provide this visibility, each with their own strengths, the user may experience tool sprawl.   In order to ease the number of tools required within an environment and move towards the goal of a “Single Pane of Glass” to manage our networks, Cloudvision Portal 2019.1.x provides a built-in IPFIX/sFlow collector that will show the top flows within a network.  Once these flows are collected, they can...

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...

SNMP support for Cloud and On-Prem deployments

Description Cloud: SNMP support for Event/Alerts (New Feature) Starting 8.8 release, Cloud customers can receive all events/alerts as SNMP traps. While configuring an SNMP trap destination server, an AP can be configured to act as CIP (Cloud Integration Point) to receive traps without exposing the SNMP destination server over the Internet. An SNMP destination server can be added through either “CloudVision WiFi” (SYSTEM -> Third-Party Servers -> SNMP-Alerts) or “Wireless Manager” UI (Configuration -> ESM Integration -> Events SNMP). To configure SNMP trap destination server through “CloudVision WiFi”, go to  “SNMP-Alerts” configuration page from the SYSTEM -> “Third-Party Servers”. Click...

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...

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...
