Cisco BPX 8600 Series Installation and Configuration
Release 9.3.10, Part Number 78-11603-01 Rev. D0, July 2001
Chapter 1 The BPX Switch: Functional Overview
Discontinued
• Enhanced Shaping of the Control Traffic
This feature limits the maximum bandwidth guaranteed by the high priority Qbins so that the
control traffic does not flood the trunk and overtake the bandwidth allocated for user traffic.
• Support for Three VSI Partitions
The BXM now supports Three VSI partitions.
• Soft and Dynamic VSI Partitioning
In Release 9.3.10, BPX switch software provides Soft Partitioning and Dynamic Partitioning of its
resources to support smooth introduction of another VSI controller into an existing BPX network
alreadyconfiguredwithanexistingVSIcontroller,easiertuningofswitchresources,andthe
migration of AutoRoute to PNNI. Soft partitioning allows a pool of resources to be used by multiple
AR and VSI controllers. Dynamic partitioning allows you alter the switch configuration without
deleting and then re-adding it. Now resources allocated to the VSI slave or VSI partition can be
reduced and redistributed between different VSI partitions. This feature facilitates the introduction
of MPLS into PNNI networks, and MPLS and PNNI or third-party controllers into existing
AutoRoute networks.
• Qbin Statistics Reporting to Cisco WAN Manager
In Release 9.3.10, BPX switch software can now collect, display, and propagate to Cisco WAN
Manager the Summary and Interval Statistics of egress Qbin numbers 10 through 15 on IGX UXM
trunks and Qbin numbers 1 through 15 on BPX BXM and IGX UXM ports. The newly added
statistics are similar to those existing on BPX trunk Qbins 1 through 9. These statistics are helpful
for monitoring system performance when using PNNI or MPLS controllers on virtual switch
interfaces.
• 800 Board Level Revision Number
The board level revision number (also known as the Manufacturing 800 number) provides the
maximum information possible about a given card, which assists in troubleshooting. This enables
Cisco Customer Service to remotely identify the board level revision number without physically
removing the card from the slot. This project provides the capability to identify the board level
revision number via command line interface, Cisco WAN Manager, or CiscoView.
• ILMI Neighbor Discovery
In Release 9.3.10, the ILMI Neighbor Discovery feature enables a network management system
such as Cisco WAN Manager to discover other external ATM devices, such as Cisco routers,
connected to the BXM card.
• Virtual Ports
In Release 9.3.10, multiple virtual ports are supported on each BXM card interface. Virtual ports
on BPX switches provide both virtual port traffic shaping and connection traffic shaping on a QOS
basis.
Discontinued
These older hardware components and technologies will be supported for five years from the time they
are discontinued:
• The BNI-155 card
• All ASI cards
