Cisco Systems 8600 Series manual Dynamic Resource Partitioning for SPVCs, Summary

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.

Tag Switching

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.
