Cisco Cisco ONS 15454 SDH Multiservice Provisioning Platform (MSPP) Notas de publicación

has been changed to:

Go to the CD directory named VcCheck and run the tool. (If you copy the 

VcCheck directory to another disk, please note that the path to the 

VcCheck directory must not contain any spaces.)

This issue is resolved in Release 4.1.4.

This section highlights new features and functionality for Release 4.1.x. For detailed documentation of 
each of these features, consult the user documentation. 

As of Release 4.1.3 the column “Path Width” has been added to Alarms, Conditions and History panes. 
The Path Width column provides the width of the VC4 path on which the alarm is raised or cleared, in 
units of VC4 (how many VC4s wide the path is). The path width only applies to the “VC4-” alarmable 
object type. For any non-VC4 object, the column remains blank.

RPR (Resilient Packet Ring) is a new protocol available on the ML-Series cards enabling you to use SDH 
bandwidth more efficiently, with 50 ms recovery times.

RPR for the ML-Series line cards provides a set of enhancements to the performance of any such card 
running the Release 4.1.x. These improvements include:

RPR for the ML-Series line cards allows new deployment applications for all cards running Release 
4.1.x. These improvements include:

Better SDH bandwidth utilization compared to an STP controlled ring topology.

Non-SDH fail-over mechanism with sub 50-millisecond convergence for fiber cuts, restores, node 
failures and inserting new nodes.

Ability to perform ML-Series QOS (quality of service) features on all SDH traffic (pass-through, 
drop, and add).

No hardware changes: Only requires ONS 15454 Release 4.1.x, which includes the new IOS 
configuration.

Increased number of supportable VLANs and MAC addresses on the ring.

A scalable, inter-ring protection mechanism for increased network resiliency. 

The addition of RPR does not remove any Release 4.0 functionality. RPR features are enabled via a 
new set of configuration commands.

For further details of RPR uses and features, consult the user documentation for Release 4.1.
