Multiple Partitioning

You can configure partition resources between Automatic Routing Management PVCs and three VSI
controllers (LSC or PNNI). Up to three VSI controllers in different control planes can independently
control the switch with no communication between controllers. The controllers are essentially unaware
of the existence of other control planes sharing the switch. This is possible because different control
planes used different partitions of the switch resources.
You can add one or more redundant LSC controllers to one partition, and one or more redundant PNNI
controllers to the other partition. With Release 9.2.3, six new templates were added for interfaces (for
a total of nine) with multiple partitions controlled simultaneously by a PNNI controller and an LSC.
The master redundancy feature allows multiple controllers to control the same partition. In a multiple
partition environment, master redundancy is independently supported on each partition.
These limitations apply to multiple VSI partitioning:

Up to three partitions are supported.
Resources cannot be redistributed amongst different VSI partitions.
The resources that are allocated to a partition are: LCNS, Bandwidth and VPI range.
Resources are also allocated to AutoRoute. The resources allocated to AutoRoute can be freed from
AutoRoute and then allocated to VSI.
No multiple partitions on Virtual Trunks. A Virtual Trunk is managed by either AutoRoute or by a
single VSI partition.
Only one controller can be added to a BPX interface. Different controllers must be added to
different switch interfaces.
