Links

You can add links between border switches of different fabrics (inter-fabric links) or between switches in the same fabric (intra-fabric links). You can only create an inter-fabric connection (IFC) for a switch that is managed by Nexus Dashboard Fabric Controller.

There are scenarios where you might want to define links between switches before connecting them physically. The links could be inter-fabric or intra-fabric links. Doing so, you can express and represent your intent to add links. The links with intent are displayed in a different color till they are actually converted to functional links. Once you physically connect the links, they are displayed as connected.

Management links might show up in the fabric topology as red colored links. To remove such links, right-click the link and click Delete Link.

The Border Spine and Border Gateway Spine roles are added to switch roles for border switches.

You can create links between existing and pre-provisioned devices as well by selecting the pre-provisioned device as the destination device.

Starting from Cisco NDFC Release 12.1.2e, parameters MTU, SPEED, Source Interface Description, Destination Interface Description, Source Interface Freeform Config, and Destination Interface Freeform Config are added to the existing int_pre_provision_intra_fabric_link template. These parameters are preserved on subsequent Recalculate & Deploy after the device has completed bootstrap and POAP.

The following table describes the fields that appear on Links tab.

Field Description

Fabric Name

Specifies the name of the Fabric.

Name

This section explains the preview functionality of the Precision Time Protocol (PTP) monitoring. PTP is a time synchronization protocol for nodes that are distributed across a network. On a local area network, it achieves clock accuracy in the sub-nanosecond range, making it suitable for measurement and control systems.

On the PTP tab in the Switch Overview window, you can view PTP-related information based on the selected switch. You can click the Telemetry Switch Sync Status link to check whether the switches are in sync. The Sync Status column displays the status of the switches.

The following tabs are displayed in this window:

  • Port Status

  • Correction & Mean Path Delay

  • Clock Status

Port Status

The Port Status table displays the status of the ports in two different views. Click on the arrow at the top-right corner to view/minimize different views.

Topology view displays the network diagram of the selected port. Hover the pointer over the switch icon to view information about role, ports and number of PTP ports. The following information is displayed:

  • switch name

  • type of port

    • specifies if it’s a follower or leader port

    • if it’s a follower port, displays the Leader and Grand Leader ports

  • interface connecting to the leader

  • number of PTP ports

Tabular view displays all the interfaces on the switch, peer link, and admin, operational and port status for the selected switch.

Click on the Filter by attributes field and choose the required attribute and enter a criteria to filter the port status and press ENTER.

Correction and Mean Path Delay

The Correction & Mean Path Delay tab displays a graph showing the PTP operational statistics: mean path delay, correction, and correction beyond threshold. You can click and drag in the plot area to zoom in and hold the shift key to pan. Click the Reset zoom button to reset zoom.

By default, the graph is displayed for the threshold value of 500 nanoseconds (ns). You can also display data based on a specific threshold value. In the Threshold (ns) field, enter the required value in nanoseconds and click Apply. Note that the threshold value is persistent in the Nexus Dashboard Fabric Controller settings, and it is used to generate PTP correction threshold Kafka notifications.

In the Date field, you can select the appropriate date to view the data. The PTP data is stored up to the last seven (7) days. The default value for the stored data is 7 days. To change this value, navigate to Admin > System Settings > Server Settings > IPFM and set the updated value for the IPFM history retention in days field.

In the Period field, you can also select a timeframe over which the data has to be displayed. The values you can choose in the Period field are Hour (1 hour), 6 hours, 12 hours, or Day (24 hours).

Note that you can click the legends in the graph to hide or display statistics.

If there are any corrections, you can view them in a tabular format by clicking the Corrections Beyond Threshold link.

To perform a refresh, click the Refresh icon.
