JSON License File for On-Premises WiFi

Description With the 8.8.1 release, the license for an on-premises Arista WiFi server is a JSON file. The JSON license is sent in an email from Arista. It contains fields such as customer information, the features supported on that deployment, platform details, and digital signature information. Note: The new licensing mechanism does not, in general, affect upgrades to existing servers. After an upgrade, an existing on-premises WiFi server with a valid license continues to operate as before. If an existing license expires, support for the new (JSON) license is provided. The application of the new license proceeds as described in...

Enabling CloudVision Wifi container on CVP

The CloudVision WiFi (CVW) service is available as a container on the Arista CloudVision platform from its 2019.1.0/Grant release. Once you activate the CVW service, you can configure, monitor, troubleshoot, and upgrade Arista WiFi access points using the cognitive CVW UI.  This chapter gives an overview of the CVW containerization on CV and explains how to set up the service. An appendix lists the CLI commands you can run on the CVW service. Overview of CVW on CV The figure below shows a conceptual overview of the Arista CVW solution.  As shown in the figure, CVW is containerized within the...

Wifi EoGRE

Hello, I’m currently testing Arista Wifi and I have issues with getting the tunneling part to work. I have setup a tunnel interface with vlan 203 and key 203. The endpoint is a Cisco ASR 1001. The SSID is set to tunneling mode, I chose that tunnel interface I just created and I can see the GRE packets going out to the ASR. I even see the DHCP DISCOVERs from my test client. However then nothing happens :( I found a few guides online and the ASR is configured like this: interface Tunnel68 mac-address 0000.5e00.0068 ip address 192.168.0.1 255.255.255.0 no...

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...

Packaging of Access Point (AP) Firmware Images on WM Server

Description This document describes a few enhancements done in Wireless Manager (WM) release 8.8 in respect of  AP firmware updates and packaging of AP firmware images in on-prem WM server. These changes affect only the on-prem WM servers that do not have HTTPs connectivity to Arista Cloud repository of AP images. On-prem WM servers that have such connectivity are not impacted. Current Behavior: Firmware images of different AP models such as. C-75, O-90, C-120, C-130, etc. are part of the WM server upgrade bundle. During server upgrade, AP images of the new build get copied onto the  WM server. When...

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...

Reports in CloudVision WiFi

Description Arista WM gathers a wealth of data about the wireless deployment. The data gathered includes Wireless Intrusion Prevention System (WIPS) related incidents, state of the devices, etc. Reports allow compact, printable and scheduled delivery of relevant pieces of information. The reports generated by Arista WM are useful for assessing the WIPS outlook of the wireless deployment, meeting regulatory compliance requirements and for inventory management. The ability to work with reports has been added to CloudVision WiFi in version 8.8. CloudVision WiFi currently supports the following types of reports. Wireless Intrusion Prevention System (WIPS) Compliance Inventory Reports about the WiFi...

Hitless WiFi AP Upgrades

Description Keeping WiFi Access Point (AP) firmware up-to-date allows network administrators to take advantage of the latest features, bug fixes, and security enhancements. The firmware of Arista APs can be upgraded via the Wireless Manager UI or CloudVision WiFi, by using any of these three techniques: New Device AP Upgrade: Newly provisioned APs can be automatically upgraded as soon as they connect to the Wireless Manager. Scheduled AP Upgrade: All the APs at a particular location can be upgraded within a particular time window—configurable in terms of specific days of the week and hours of the day. The schedule can...
