Cisco BPX 8600 Series Installation and Configuration
Release 9.3.0, Part Number 78-10674-01 Rev. D0, July 2001
Chapter 23 Configuring BXM Virtual Switch Interfaces
VSI Configuration Procedures
Step 2
Delete the SES attached to the trunk interface by using the delshelf command.
Step 3 Disable the VSI resource partition allocated for PNNI controller on the trunk interface by using the
cnfrsrc command.
Step 4 Down the trunk interface (provided no other VSI partitions are active on the trunk interface) by using
the dntrk command.
Configuring Partition Resources on Interfaces
This section is key for configuring VSI.
Prior to release 9.1, LCNs, VPI range, and Bandwidth allocation were managed exclusivelyby the BCC.
With the introduction of VSI, the switch must allocate a range of LCNs, VPIs, and how much bandwidth
for use by VSI (not BXM).
When configuring resource partitions on a VSI interface, you typically use the following commands:
•
cnfrsrc
• dsprsrc
• dspvsipartinfo
•
dspvsipartcnf
• uptrk
• upln
•
upport
The next step to complete when adding a VSI-based controller such as an LSC (Label Switching
Controller) or a PNNI controller is to configure resource partitions on BXM interfaces to allow the
controller to control the BXM interfaces. To do this, you must create resource partitions on these
interfaces. Use the cnfrsrc command to add, delete and modify a partition on a specified interface.
You may have up to three VSI controllers on the same partition (referred to as VSI master redundancy).
The master redundancy feature allows multiple VSI masters to control the same partition.
See Table 23-1 for a listing of cnfrsrc parameters, ranges and values, and descriptions. These
descriptions are oriented to actions and behavior of the BXM firmware; in most cases, objects
(messages) are sent to switch software. Most of these parameters appear on the cnfrsrc screen.
Table 23-1 cnfrsrc Parameters, Ranges/Values, and Descriptions
Parameter
(Object) Name
Range/Values Default Description
VSI partition 1... 3 1 Identifies the partition
Partition state 0 = Disable
Partition
1 = Enable
Partition
NA For Partition state = 1, Objects are mandatory
Min LCNs 0...64K NA Min LCNs (connections) guaranteed for this
partition.
Max LCNs 0...64K NA Maximum LCNs permitted on this partition
