vPorts and Connections
vPorts & Connections
There are features and functions used in Arista NetVisor UNUM and Insight Analytics that are common throughout the user interface (UI). Please refer to the Common Functions section for more information on the use of these functions and features.
NetVisor OS uses vPort (or virtual port) as Layer 2 entries managed by the software and associated with ports where a node performs MAC address learning. vPorts contain information such as the MAC and IP address of a host, the VLAN and the connected port, the state, and other parameters.
In a fabric, a node only sends status updates for vPorts that are part of the fabric, which means that it sends updates only for the states of the hosts directly connected to that node. NetVisor OS uses"owned vPorts" to represent directly connected hosts.
On the NetVisor UNUM Topology dashboard, the 
icon signifies the switch/router contains NetVisor OS vPorts, while a number, 
, indicates the number of connections running between the devices.
