Description

Detailed View in NFV for Transponder and Muxponder Card on Third-party OLS Networks 

Cisco IOS XR Release 24.2.1

The Node Functional View (NFV) has been enhanced to provide a detailed view of transponder and muxponder cards on NCS1014 deployed within networks utilizing third-party Optical Line Systems (OLS).

This detailed view provides a graphical representation of the connections between the trunk and client ports on the transponder and muxponder cards, thereby simplifying the visualization of the network's connection layout.

Detailed View in NFV for Transponder and Muxponder Cards on OLS Networks

Cisco IOS XR Release 24.1.1

You can now access a detailed graphical representation of the connections between the trunk and client ports of the transponder and muxponder cards on Optical Line System (OLS) NCS 1010 networks. This is available in the Map View of Node Functional View (NFV).

This view is based on the card mode configured on the cards. When you access the detailed view, the right-panel of the Node Functional View displays the card mode details and a list of ports and their settings.

Understanding Node Functional View

The Node Functional View (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 Cisco Optical Site Manager web interface and selecting Node Functional View.

There are three views in the NFV representation:

View

Description

Rack view

Displays a visual representation of a rack, including the node and all its cards.

Map view

Displays a visual map of the components of the node (sides, cards, and so on), connected by patch cords according to physical connections.

In this view, you can switch between different contexts, such as the node view, side view, card view, circuit view, port view, and patch cord view. Based on the chosen context, the relevant details are displayed on the right side of the screen.

When you expand a node or a branch in the map view, the cards associated with them are highlighted in the Rack view. Similarly, when you expand a card in the map view, the card is zoomed in and the corresponding rack is highlighted and zoomed in the Rack view.

In the Map view, you can view the connection between the trunk and client ports on a card as well as the Internal Patch Cords (IPC) connecting the devices and line cards. The connections are based on the card modes configured on a card.

Detail view

Displays all relevant information about nodes, sides, cards, circuits, ports, or patch cords. This view also displays card mode details and a list of ports and their settings when you access a card in the Map view.

Alarm Status

The highest alarm severity appears as the overall status on the right. Possible alarm statuses, sorted by severity, are:

  • Normal - Displayed with White color

  • Minor - Displayed with Yellow color

  • Major - Displayed with Orange color

  • Critical - Displayed with Red color
