Hello gents, It may sound silly but have been unable to find details about this especific operation on CloudVision. For demonstration purposes to a customer, we would like to remove a switch from CloudVision and onboard it like it was brand new. We could stop eAPI and streaming agent daemon at the device level to be able to Decommission it at the portal, and it actually dissappears, but as soon as we re-engage state streaming at the switch, it pops back up at CVP. I take it TerminAttr retains the CVP config and starts live feeding once it has been...

CVP not booting – No space left on device

I have encountered an issue with my CloudVision VM. After a while the web GUI stopped to respond, the login screen didn’t appeared. I reloaded the CVP VM but even after that CVP can’t boot up. Login to the shell I can see only the Localhost interface is up. When I try to verify my cvp config (su cvpadmin, verify) I receive error: no space left on device. But when checking cvpi resource it seems there is enough free space (see 2.png). When trying to start cvpi with cvpi start all command I receive some ZK lock coulnd’t be created:...

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 Wi-Fi 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...
