Sites

About Sites

Sites are on-premises network regions that consist of a group of switches and other networking devices that provide connectivity for your applications and endpoints. You can split sites into different availability zones, such as pods, that are analyzed and managed by Nexus Dashboard Insights.

Types of on-premises sites

  • Online sites: Multiple Nexus switches running ACI or NX-OS that can be represented by a controller such as APIC or NDFC and connected to Nexus Dashboard Insights to continuously stream telemetry. Types of online sites include:

    • ACI: Multiple Nexus switches with Cisco ACI and represented by a Cisco APIC.

    • NDFC: Multiple Nexus switches with Cisco NX-OS and represented by a Cisco NDFC.

    • NX-OS: A group of Cisco Nexus 9000 switches running NX-OS without a controller.

  • Snapshot sites: Controller-based sites, that are referenced by a snapshot, for use in one-time analysis or demonstrations. They may or may not be connected to Nexus Dashboard Insights over the network.

To learn about how to prepare sites for onboarding, see Add Sites.

A NDFC site is comprised of a fabric running NX-OS that is either fully managed or only monitored by NDFC. All of the switches in the fabric can be analyzed as a part of the site. With a NX-OS based fabric, the fabric could be a NDFC managed fabric or it could be configured using other means such as CLI, Ansible, or any other configuration automation mechanism. For fabrics not using NDFC for configuration management, NDFC must be installed and the fabric must be discovered in read-only or monitor mode. Nexus Dashboard Insights uses NDFC for topology discovery and to identify the role of the switch in the fabric.

A NX-OS site is comprised of Nexus 9000 switches, that run NX-OS without a controller and is connected to Nexus Dashboard.

Once your site is onboarded and fully prepared, Nexus Dashboard Insights will start the site analysis to collect data from your site and display the site information in the Sites page. See Site Details. From there, you can view your site’s general information, inventory, L2 and L3 connectivity, endpoints, anomalies and advisories and more! To learn more see Site Details.

Prerequisites

  • You have configured DNS on the fabric.

  • You have configured NTP on the fabric.

  • You have configured PTP on the fabric

  • You have configured in-band management network with loopback interfaces on the switches and the Nexus Dashboard data interface have routed connectivity to those.

  • If the switches are controlled by NDFC and they are discovered using out-of-band management interface, then Nexus Dashboard data interface should have routed connectivity to those.

  • You have configured Fabric connectivity in Cisco Nexus Dashboard. See Cisco Nexus Dashboard Platform Overview.

  • You have the supported software version for your fabric. See Nexus Dashboard and Services Compatibility Matrix.

  • For snapshot sites, you have Python3 installed on your system.

  • To onboard a NX-OS site without a controller:

    • You must enable NX-OS Discovery in Nexus Dashboard.

    • You must enable CDP or LLDP in Nexus switches.

    • Nexus switch management IP address should be reachable to Nexus Dashboard management network.

    • Nexus switch in-band port address should be configured on loopback interface and should be reachable to Nexus Dashboard data network.

Guidelines and Limitations

  • You cannot onboard a NDFC site with remote authentication using the Manually Add option in Nexus Dashboard Insights. You must first add the NDFC site with remote authentication in Nexus Dashboard. You can then onboard the NDFC site using the Ready to Add option in NDI.

  • Switch name or Host name should be unique across all the fabrics discovered in Nexus Dashboard Insights.

  • SVI interfaces are not displayed for Cisco NX-OS switches.

  • You must enable the NX-API feature on all Cisco NX-OS switches at the CLI prompt before onboarding the site in Nexus Dashboard Insights by using the following command:

    switch(config)# feature nxapi
