Cisco BPX 8600 Series Installation and Configuration
Release 9.3.30, Part Number 78-12907-01 Rev. E0, May 2005
Chapter 23 Configuring BXM Virtual Switch Interface
Overview: How VSI Works
Partitioning
The Virtual Switch Interface must partition the resources between competing controllers, Automatic
Routing Management, MPLS, and PNNI for example. You partition resources by using the
cnfrsrc
command.
Note
Release 9.3 supports up to three partitions.
The three resources that must be configured for a partition designated ifci, which stands for interface
controller 1 in this instance are listed in Table 23-1.
Some ranges of values available for a partition are listed in Table 23-2.
When a trunk is added, the entire bandwidth is allocated to Automatic Routing Management. 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.
