• Local event reduction: regular-expression filters
(dropping), suppression of flapping events, etc.
• Grouping of related events (same cause) into
alarms
• Model-based alarm correlation, to identify
causality
– Local correlation: alarms emitted within a single NE
– Topology-based correlation: alarms from multiple
NEs

Soft Properties
Add new properties to an existing network element
or network element family.
Support template variables (for example,$ifindex$) for
instance-referencing, parsing rules, and regular
expressions.
VNE Customization Builder (VCB)
Field extension for additional device modules,
events, and software releases

Cisco Prime Network is extensible because of the following customization tools
WORKFLOW
UI wizard to define and run sequence of
commands (created using Command Builder tool)
across the network
Powerful and configurable workflow logic (for example, If,
Else, and multibranching; looping; And, Or, and X or; parallel
and sequential tasks; and recursive invocations)
Execution control (runtime, scheduling, and automatic
rollback support)
COMMAND BUILDER
UI wizard to define, preview, and run commands.
Commands can be associated (published) with object
group or instances
The wizard offers advanced programmatic control.
Comprehensive Customization Toolkit

• Faster service interruption detection
Visualization of service provider’s backbone
network services
Service views Mapping of VPN/MPLS tunnels
Forwarding of virtual routing instances alarms in real
time
• Improved time-to-restore
Immediate root-cause analysis because of
intelligent alarms correlation
Improvement of service interruption time-to-restore
• Reduce troubleshooting time
Reduced troubleshooting time and enhanced user
experience through the use of the following tools:
Path tracer: Point-to-point complete discovery and
real-time tracing and analysis of service paths
Command builder: Enables users to define, preview,
and run activation and diagnosis commands
Logical inventory: Topology representation of logical
inventory: that is, EtherChannel links and associated
ports used for aggregation

Two key benefits:
• Direct support for network operation
Timely updates protect your investment
Network element administration and configuration & change management ensure a
stable and predictable network
Reducing mean time to repair for network problems improves efficiency
• Facilitating external OSS infrastructures
Reducing the need for replication of mediation and abstraction layers
Simplifies programmatic access to all Cisco Prime Network details
Access to software development kits (SDKs), extensive
documentation, and programming examples and reusable
reference applications
