Node Functional View

This chapter describes the Node Functional View (NFV) used in Cisco NCS 2000 SVO and its related tasks.

Understanding Node Functional View

The NFV 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.

The NFV can be accessed by clicking the hamburger icon at the top-left of the page in SVO web interface and selecting Node Functional View.

There are three views in the NFV representation:

View

Description

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, cards, and so on). The components are connected to each other using patch cords, according to the physical connections.

You can have different context in the map view such as node view, side view, card view, circuit view, port view, and patch cord view. The appropriate details are displayed in the right shoulder based on the context in the map view.

When you open a card in the map view, the card is zoomed and the corresponding rack is highlighted and zoomed in the physical view.

You can view the circuits and patch cords at node view, side view, card view, and port views.

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.

Alarm Status

The highest alarm severity is displayed as the overall status in the right shoulder. The possible alarm statuses, sorted by severity level, are:

  • Normal - Displayed with White color

  • Minor - Displayed with Yellow color

  • Major - Displayed with Orange color

  • Critical - Displayed with Red color
