Chapter 23 Configuring BXM Virtual Switch Interface
Class of Service Templates and Qbins
Figure 23-9 Service Template Overview
Qbin templates are used only with Qbins that are available to VSI partitions, specifically, Qbins 10
through 15. Qbins 10 through 15 are used by the VSI on interfaces configured as trunks or ports. The
rest of the Qbins (0–9) are reserved for and configured by Automatic Routing Management.
Each template table row includes an entry that defines the Qbin to be used for that Class of Service. This
mapping defines a relationship between the template and the interface Qbin’s configuration. As a result,
you need to define a default Qbin configuration to be associated with the template.
Note
The default Qbin configuration, although sometime referred as a “Qbin template,” behaves
differently from that of the Class of Service templates.
SC stands for Service Class. Each pre-configured template is one of the
above for each of 3 service templates (VC Da Qbin (10-15)
