Configuring Enhanced BXM Cards to Support 60K Connections

The Enhanced BXM model DX and EX can support up to 60K connections. BPX software releases prior
to 9.3.30 provide support for only up to 32K connections for both VSI and non-VSI connections. Current
versions of the software now allow attached VSI controllers to manage up to 60K connections per
enhanced BXM card (model DX or EX). The maximum number of connections (PVCs) managed by the
BCC is still at 32K.
The software automatically configures any newly installed BXM-E DX or EX cards to support 60K
connections. For existing BXM-E cards that had been configured for 32K connections, a new "super
user" CLI, upgdvsilcn, is provided for configuring them to support 60K connections. Once the card has
been configured for 60K connections, VSI resource partitions on the card can be changed using the
cnfrsrc command to take advantage of the added number of connections available for VSI.
The upgdvsilcn command can be executed on a standalone BXM configuration or Y-redundancy
configuration. The command is hitless and does not impact existing connections. For a detailed
discussion of the upgdvsi and related commands, refer to the Cisco WAN Switching Command
Reference.

Soft and Dynamic Partitioning

Soft and Dynamic Partitioning (new in Release 9.3.10) supports smooth introduction of another VSI
controller into an existing BPX network already configured with an existing VSI controller, easier tuning
of switch resources, and the migration of Automatic Routing Management to PNNI.
Soft Partitioning provides resource guarantees for LCNs and bandwidth per partition and a pool of
resources available to all partitions in addition to the guaranteed resources. Dynamic Partitioning
provides the ability to rather easily increase the allocation of a resource to a partition.
Define and manage the number of LCNs assigned to a given VSI partition by modifying the "Minimum
VSI LCNs" and "Maximum VSI LCNs" fields of the cnfrsrc CLI command.
To give more LCNs from Automatic Routing Management to VSI, change the Min LCNs or Max LCNs
to cause BPX software to produce a bigger number.
To increase the LCNs reserved to a VSI partition, increase the "Minimum VSI LCNs" or "Maximum VSI
LCNs" fields of the appropriate VSI partition. The VSI LCN boundary is moved into Automatic Routing
Management if there are enough free Automatic Routing Management LCNs to fulfill the request.
