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
VSI Configuration Procedures
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 VSIs.
Prior to Release 9.1, LCNs, VPI range, and bandwidth allocation were managed exclusively by 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, the following commands are typically used:
• cnfrsrc
•
dsprsrc
• dspvsipartinfo
•
dspvsipartcnf
•
uptrk
•
upln
• upport
The next step to complete when adding a VSI-based controller such as an LSC or a PNNI controller is
to configure resource partitions on BXM interfaces to allow the controller to control the BXM interfaces.
To do this, first 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.
The cnfrsrc parameters, ranges and values, and descriptions are listed in Table 23-5. 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 23-5 cnfrsrc Parameters, Ranges/Values, and Descriptions
Parameter
(Object) Name
Range/Values Default Description
VSI partition 1 to 3 1 Identifies the partition
Partition state 0 = Disable Partition
1 = Enable Partition
— For Partition state = 1, Objects are mandatory
Min LCNs 0 to 64K — Minimum LCNs (connections) guaranteed for
this partition.
Max LCNs 0 to 64K — Maximum LCNs permitted on this partition
Start VPI 0 to 4095 — Partition Start VPI
End VPI 0 to 4095 — Partition End VPI
