Fabric and Network Settings


Enabling Web Access on NetVisor OS


If you use ZTP (Zero Touch Provisioning) to deploy NetVisor OS on your switches, Web / Rest services are automatically configured.


If you do not use ZTP to deploy NetVisor OS, you must activate Web / Rest services on the switch management or data interface connected to NetVisor UNUM using the CLI, on each switch in the fabric:


Out-of-Band Management


Use the following command:


CLI (network-admin@pubdev02) > admin-service-modify if mgmt web


InBand Management


Use the following command:


CLI (network-admin@pubdev02) > admin-service-modify if data web


For more information on configuring Inband Management refer to NetVisor UNUM Inband Connection and Configuration in this guide.


Enabling sFlow on NetVisor OS


Note: As of July 2021, sFlow is no longer supported.


For more information on configuring administrative services, sFlow, and vCenter Connection service, refer to the NetVisor OS Configuration Guides. 


Enabling vCenter Service on NetVisor OS


For more information on configuring administrative services, sFlow, and vCenter Connection service, refer to the NetVisor OS Configuration Guides


Performance Tuning NetVisor OS for Maximizing Connections for NetVisor UNUM


On each switch in the fabric that is seeing traffic and to maximize the connections pulled from NetVisor UNUM Insight Analytics Flow, the following parameters should be modified:


NetVisor OS:


connection-stats-settings-modify connection-stats-log-disk-space 50M 


connection-stats-settings-modify connection-max-memory 50M


Monitoring Third Party Switches


If you want NetVisor UNUM Insight Analytics Flow to monitor a third-party switch, use the following steps to configure the port on the Arista Networks switch that is directly connected to the third-party switch:


1.Configure the mirror parameter for the port entering the following command: 

network-admin@switch-name>port-config-modify port port-number mirror-only


2.Block STP on the port entering the following command: 

stp-port-modify port [x] block
