Overview: How VSI Works

Partitioning

The VSIs need to partition the resources between competing controllers, Autoroute, Label Switching,
and PNNI for example. You do partitioning by using the cnfrsrc command.
Note Release 9.3 supports up to three partitions.
For Release. 9.1 and Release 9.2, just one controller (of a particular type) is supported. However, you
can have different types of controllers splitting up a partition's assets. For example, Autoroute and
Label, or Autoroute and PNNI (svcs), and both PNNI and MPLS.
Table 23-2 shows the three resources that must be configured for a partition designated ifci, which
stands for interface controller 1 in this instance.

vpi
The controller is supplied with a logical lcn connection number, that is slot, port, and so on., information
that is converted to a logical connection number (lcn).
Some ranges of values available for a partition are listed in Table 23-3:

When a trunk is added, the entire bandwidth is allocated to Autoroute. To change the allocation in order
to provide resources for a vsi, use the cnfrsrc command on the BPX switch. A view of the resource
partitioning available is shown in Figure 23-5.
