Fabric Layer 1 – Virtual Topology - Manage Topology vLink

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.

Manage Topology vLink

Please refer to the Packet Broker and VirtualWire sections for more information about vPGs.

Selecting Manager → Layer 1 → Virtual Topology → Manage Topology vLink displays the Manage Topology vLink dashboard with a list of any existing vLink entries.

Note: If no entries exist a "No Data Exists" message is displayed. You must first configure an entry on a switch. Prerequisite settings and configuration may be required.

Add a vLink

After creating a virtual topology using Manage Topology, select the topology from the drop-down list.

Usage Notes:	1.The virtual topology must be disabled before adding, modifying, or deleting a vLink. Refer to the Manage Topology section for more information.
	2.The vPGs that are part of a topology must be present in the fabric before enabling the topology. NetVisor UNUM raises an error if you try to enable a topology for vPGs that do not exist.
	3.NetVisor OS supports topologies with vFlows having fabric scope only.
	4.Two or more vFlows with a common bidirectional vPG are not supported.
	5.vPGs must be bi-directional. You cannot specify source or destinations as endpoints of a vLink.

Select Add vLink and enter the requisite parameters, which include:

•Switch – Select a Switch.

•Topologies – Pre-populated from drop-down list selection.

•EndPoint 1 – Select a VPG from the drop-down list.

•EndPoint 2 – Select VPG from the drop-down list.

•vLink Name – Provide a name for the vLink.
