Port CoS BW
NetVisor OS automatically weights Class of Server (CoS) queues with minimum bandwidth guarantees. When you configure minimum bandwidth on a port queue using CoS, the remaining bandwidth gets assigned to the rest of the queues in the same ratio as the minimum bandwidth.
Selecting Manager → Services → Port CoS BW displays the Port CoS BW dashboard with a list of any existing Port CoS BW settings.
Select the applicable Fabric from the left-hand navigation bar and the dashboard updates showing all Port CoS BW 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.
The dashboard displays a list of existing Port CoS BW entries by Fabric name.
Additional parameters include: Switch, CoS, Port, Weight, Min Bw Guarantee, and Max Bw Limit.
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.
