Chapter 23 Configuring BXM Virtual Switch Interfaces
Class of Service Templates and Qbins
Qbin Dependencies
Qbin templates deal only with qbins that are available to VSI partitions, namely 10 through 15. Qbins
10 through 15 are used by VSI on interfaces configured as trunks or ports. The rest of the qbins are
reserved and configured by Automatic Routing Management.
When you execute a dspsct command, it will give you the default service type, and the qbin number.
The available qbin parameters are shown in Table 23-12.
Notice that the qbins available for VSI are restricted to qbins 10–15 for that interface. All 32 possible
virtual interfaces are provided with 16 qbins.
