Security/Monitoring vFlow


There are features and functions used in UNUM Manager and UNUM 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 vFlow


Selecting Manager → Security/Monitoring → Manage vFlow displays the Manage vFlow dashboard with a list of any existing vFlow settings. 


The vFlow functionality in Netvisor ONE is a unique Pluribus feature, which defines fabric-wide policies (using match conditions) for line-rate control as well as facilitate the  manipulation  and redirection of traffic flows using physical or logical filtering methods (using action parameters). Netvisor ONE implements vFlow objects in hardware that have no impact on the forwarding performance of the switch and vFlows can be applied to traffic flows regardless of the forwarding method or provisioning construct employed. As such, vFlow objects can be implemented for bridging, routing and extended bridging operations and also for transparent forwarding services such as VirtualWire and Virtual Link Extension (vLE).


Select the applicable Fabric from the left-hand navigation bar and the dashboard updates showing all vFlow entries from all switches within the Fabric


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.



This feature table displays data based on the fabric's default Collector Switch. If no data displays in the dashboard, either select a switch from the Left-hand Navigation (LHN) pane or perform a Search by selecting an FRG (Fabric Resource Group) and a specific Attribute from the drop-down lists, as required. 



The dashboard displays data based on the default Collector Switch ( in this example, aries-unum-spine1).

Manager Security/Monitoring Manage vFlow - Searchable Attributes


Note: An FRG must exist before being selectable in the FRG selection box. Refer to Manage Groups and Fabric Virtualization for more information on creating and using FRGs.


Enter the search criteria for the selected attribute or FRG and click the Search button.


Select the applicable switch from the fabric and the dashboard updates automatically with vFlow settings. 


The dashboard displays a list of existing vFlows by name. Additional parameters include: Scope, VLAN, Precedence, Enable, Action, Source IP, Destination IP, BW Max, and Burst Size.


vFlows are added by selecting Create a virtual flow for L2 or L3 IP
