What's New in NCS 2000 Series, Release 12.1

This section highlights the new features in Release 12.1.

Software Features

Node Functional View

The NFV (Node Functional View) provides you with a display of the components and the association links between them in a Graphical view. The graphical representation allows you to understand the connections and also guides you to troubleshoot.

There are three views in the NFV representation:

  • Physical view: Displays a physical representation of the node with the rack and all the cards inside.

  • Map view: Displays a map representation of the node in terms of components (sides, line cards, optical modules, circuits, ports, or patch cords). The components are connected to each other using patch cords, according to the physical connections.

  • Detail view: Displays all the relevant information about the node, side, card, circuit, port, or patch cord depending on the context in the map view.

See Node Functional View.

Support for RADIUS or TACACS-based Authentication

NCS 2000 Release 12.1 Nodal Craft supports RADIUS or TACACS mode of external authentication. You should have SVO instances with RADIUS and TACACS IP addresses in the Cisco Secure ACS server. Ensure that you enable and use either RADIUS or TACACS authentication method at a time. You can add a maximum of up to ten servers for each of RADIUS or TACACS on SVO.

See Manage External Authentication.

Single Sign On for Evolved Programmable Network Manager

NCS 2000 Release 12.1 Nodal Craft allows you to configure Single Sign On (SSO) capability from EPNM. This allows you to redirect from EPNM to SVO without additional sign-on request. For example, if you have a specific alarm present in EPNM and when you click that alarm from EPNM, you can directly navigate to that specific alarm page or global alarm page of SVO. Ensure that the EPNM is configured for SVO navigation pages and SSO is enabled on SVO.

See Log into the SVO Web Interface Using EPNM.

Cisco SVO Admin Plane

Cisco SVO admin plane is responsible for turning up the shelf virtualization orchestration services for the network elements (NE). It is a web user interface that facilitates the installation of the SVO software and configures the NE instances and orchestrates high availability (HA) services.

The admin plane is supported both on the external server and the SVO card. The admin plane allows you to create, update, manage, and delete SVO NE instances.

See Cisco SVO Admin Plane.

IPv6 Support

External server solution supports IPv6 along with IPv4. You can configure IPv6 or IPv4 independently for the three networks (Management, HA, and Devices) during external server installation.

See Cisco SVO Admin Plane Overview.

Alarm Suppression on ECU MSM Ports

NCS 2000 Release 12.1 Nodal Craft allows you to suppress the alarms on the MSM ports of ECU. It allows you to verify the alarm suppression settings on the ECU.

See Suppress ECU Multishelf Ports Alarm.

External Switch as a Device

NCS 2000 Release 12.1 Nodal Craft allows you to add an external switch as a device to a ROADM instance. The external switch can be configured with the respective IP settings. A maximum of two switches can be added for each SVO ROADM instance.

See Configure External Switch.


The following alarms are added.




See Alarms.

Hardware Features

100GE-FR QSFP28 Pluggable Support on 400G-XP-LC Card

QSFP-100G-FR-S pluggable is supported on the 400G-XP-LC card. This pluggable supports only the 100GE interface.

See PPM Compatibility by Card.


A new passive optical multiplexer and de-multiplexer module, NCS1K-MD-64-C, is introduced. The new optical module is based on Athermal Wave Guide (AWG) providing 64 channels at 75-GHz space covering the extended C-band of optical spectrum. The passive module allows you to transmit 400G ZR and 400G ZR+ wavelengths.

See Installing the NCS1K-MD-64-C Module.
