Concurrent Routing—Allows the switch CPU to be more effectively utilized by allowing the routing
of multiple connection bundles to be in progress concurrently. The result is better overall reroute
performance. If Concurrent Routing is not enabled, only one bundle at a time can be routed on a
node.
TFTP Configuration Save/Restore—Provides the option to use TFTP for communication between
the nodes and the network management system, and the ability to run more efficient configuration
downloads on large networks. The use of the standard TFTP allows the backup and restoration of
BPX configuration files to workstations or network servers running UNIX and standard TFTP
software.
Virtual Trunk Clock Source Synchronization—Makes network synchronization to a single ATM
service provider clock source more reliable by minimizing clock source switching when there is a
single point failure.
60K Connections Support on BXM-E—Provides the ability to support a maximum of 60K per card
for VSI applications for the BPX 8600, for example, PNNI or MPLS, used on enhanced BXM-E
cards.
F4 to F5 Mapping—Enhances end-to-end connection management and VPC failure notification,
mapping VPC-based OAM flows into the equivalent VCC OAM flows for each VCC within the
VPC.
Trunk Incremental Cell Delay Variance—Allows more voice or NTS connections to be routed over
a trunk by providing a way to adjust the assumed transmission latency on the trunk. The Trunk
Incremental Cell Delay Variance (CDV) improves the availability of a node or a network.
Virtual Port ILMI Enhancement—Provides support of the ILMI link management protocol that is
extended to BXM physical interfaces, which are configured with virtual ports. LMI continues to be
supported on BXM physical ports only.
Virtual Trunk AIS OAM Recognition Enhancement—Provides the capability for virtual trunk
interfaces on BXM cards to recognize the receipt of end-to-end F4 AIS OAM cells as a virtual trunk
path failure alarm condition.
800 Part Number Support for BXM Back Cards—Extends the support for displaying Cisco 800-level
part numbers (Top Assembly Numbers) to BXM back cards.
VC Merge—Improves the scalability of MPLS networks and allows multiple incoming Virtual
Circuit (VCs) to be merged into a single outgoing VC, which is called merged VC. While preserving
AAL5 framing, the key to VC Merge is to switch cells from the merging Label Virtual Circuit (LVC)
to the merged LVC that points to the destination.
