Resource Partitioning
Resource Partitioning
Starting with switch software Release 8.4, resources on BPX switch UNI ports and NNI trunks can
be divided between SVCs and PVCs. This is known as resource partitioning and is done through the
Command Line Interface for the BPX switch and the MGX 8220.
These resources for BXM, ASI, and BNI cards can be partitioned appropriately between SVCs or
PVCs.

Starting with switch software release 9.1, the BXM also supports tag switching. Partitions for the
BXM can be allocated either between:
• SVCs and PVCs, or
• Tag switching virtual circuits (TVCs) and PVCs.
For information on Tag Switching, refer to Chapter 9, Tag Switching.
Dynamic Resource Partitioning for SPVCs
Also, for switch software Release 9.1, the BXM card supports dynamic resource partitioning to
support the conversion of PVCs to soft permanent virtual circuits (SPVCs). This feature is described
in the Cisco WAN Service Node Extended Services Processor Installation and Operations for
Release 2.2 document.
Summary
This section provides procedures for:
• UNI Port Resource Partitioning, BXM and ASI
• NNI or Trunk Resource Partitioning, BXM and BNI
Note Resource partitioning also has to be done for the line between the ESP ATM NIC and the
BXM in the BPX switch. Refer to the Cisco WAN Service Node Extended Services Processor
Installation and Operation for Release 2.2 document.
