New features for Cisco Optical Network Planner, Release 26.1.1

Product impact

Feature

Description

 

        Cisco Optical Network Planner Configuration

 

 Software Reliability

Reusable predefined user profiles

Now you can save all network and site-level settings into a reusable profile file, in the CONP database. You can use this profile during network designing, ensuring consistent configurations across different designs and teams. This feature eliminates repetitive manual setup, reduces errors, and streamlines configuration sharing and management within an organization.

 

 

 Software Reliability 

Live network import enhancements

The live network import feature now offers the following enhancements:

●     Supports the NCS 1001 platform.

●     Handles colored, colorless, and mixed configurations for NCS 2000.

●     Includes all NCS 1000 native transponders for NCS 2000, NCS1010, and NCS1001 platforms.

●     Imports network with mixed nodes by grouping NCS2000, NCS1010, and NCS1001 nodes into separate, platform-specific Cisco ONP networks.

 These improvements enhance network planning, boost automation, and ensure consistent, error-free network upgrades and configurations.

 

 Software Reliability 

CONC licenses support

Two new network-level properties, CONC License Package and CONC Term Preference, have been introduced to the Network application configuration category. Depending on the selected properties, the following licenses may be included in the BOM: CONC RTM ESS SM, CONC RTM SPC SM, CONC RTM API SM, CONC RTM ESS LG, CONC RTM SPC LG, and CONC RTM API LG. This feature allows you to identify and order the necessary COSM and CONC licenses for your comprehensive Optical Automation Software (OAS) solution based on the network configuration.

 

 Software Reliability

 COSM enhancements

COSM application memory and COSM RAM Size are considered for COSM association through COSM Application Memory and COSM RAM size properties at site level.

 

 Software Reliability 

Cisco ONP BoM based on license offer structure

Cisco ONP introduces a network-level Licensing Model option within the Bill of Materials category. You can select between Smart Licensed and Perpetual licensing models for your deployment. This feature is available on NCS 1010, NCS 1014, NCS 1001, NCS 2000 4K-1K-2K SSON networks. The generated BoM will accurately represent the hardware, software, and licenses that can be ordered for the chosen Authorize-to-Order (ATO) bundle. This enhancement ensures that the BoM aligns with your specific licensing needs, allowing for flexible and precise license selection within Cisco ONP. Consequently, order accuracy and compliance with Cisco’s licensing models are enhanced, offering greater flexibility and transparency when configuring solutions in Cisco Commerce Workspace (CCW).

 

 Software Reliability 

2x100G muxponder mode support on NCS1K14-2.4T-X-K9 transponder card

Cisco ONP enables the 2x100GE muxponder mode on the NCS1K14-2.4T-X-K9 transponder card when designing networks for the NCS 1010, NCS 1014, CS 1001, and NCS 2000 (1k-2K traffic site) platforms. This mode supports trunk rates ranging from 400G to 1.2T (excluding 700G) for both slice-0 and slice-1, and is compatible with client pluggables QDD-2X100-CWDM4-S and QDD-2X100-LR4-S. The 2x100G mode provides flexible and efficient aggregation of 100GE traffic, optimizing resource utilization and simplifying service provisioning within each platform's design.

 

 Software Reliability            

NCS 1010 network design enhancements

Cisco ONP has implemented the following enhancements for network design:

 ALC Phase II Device Parameters:

·       NETCONF XML files now include additional ALC phase II parameters such as Raman amplification and advanced optical settings for more precise device configuration.

·       Lookup Table (LUT) Improvements:

·       Raman gain values are now visible in LUT entries.

·       LUTs can be imported/exported, including CPZ data.

·       Raman side amplification is calculated from LUT entries for better modeling accuracy.

·       Tx connector loss is user-configurable and factored into PSD values.

 SSF simulation enhancements:

·       Uses secure HTTPS protocol for communication with SSF server.

·       Supports multi-subnet network analysis.

·        Displays estimated simulation timing in the analysis progress bar.

·       Enables background analysis without interrupting other tasks.

·       These updates enhance the accuracy, configurability, security, and usability of optical network planning and simulation for NCS 1010 networks.

 Software Reliability 

NCS1K14-FAN-P programmable fan for NCS 1014

The new NCS1K14-FAN-P programmable fan reduces power use and improves cooling efficiency by adjusting its speed to match the card load in the NCS 1014 chassis. It increases speed automatically when the chassis drives higher bandwidth or thermal demand, keeping airflow aligned with power requirements. Choose the programmable fan from the new NCS1014 Chassis Fan field at the network level.

 

 Software Reliability
