Map A/B Path

You can use the Path Calculator to map the traffic flow between two endpoints, or from a receiver to a source (multicast network) and then monitor your network traffics based on the visualized path.

Calculate a Unicast Path

  1. Click the path icon on the search bar.

  2. Enter the source and the destination IP addresses (device hostnames or DNS names).
    Information
    Tip: The 1st Hop Map function can help you choose the first hop.

  1. Click the  icon and then select  or the icon to select the path direction. By default, the system calculates one-way paths.
    Information Tip: To quickly swap the source and the destination IP addresses, click the  icon.
  2. If an endpoint has multiple gateways, select the correct one from the Gateway list, or select any device's interface with IP as the gateway for the end system.
    Information

    Tip: To configure the data source, protocol, and other advanced settings for path calculation, click the  icon to make changes. See Path Settings for more reference.
    Information Note: Only the current device's interface with configured IP can be chosen as the gateway for a network device.
    Information Tip: You can predefine gateways for end systems in batch in your NetworkBrain domain. With the definition, the system automatically looks up the matched gateways for the source and destination during a path calculation without having to re-selecting the gateways. See Predefining Gateway Fix-up Rules for details.

  3. Click the path to start calculating the path. A map is automatically created to draw the path hop by hop.

    Information

    Tip: The system determines which path type to calculate based on the network topology type the traffic goes through. For example, a traffic path goes through an interface with L2, L3, and overlay topology types, and the system will calculate three types of paths (L2 path, L3 path, and overlay path). You can click a path type in the Path Result pane to show the corresponding path on the map.  

    Note: The technology tag for each Path hop is checked by the path discovery logic. 
  1. (Optional) Click the icon in the Path Result Pane and select Save Path to save the path to the Path Browser.

Calculate a Multicast Path

  1. Click the path icon on the search bar.
  2. Click the Setting icon A picture containing text Description automatically generated and select Multicast as Path type.

  3. Enter a Multicast Receiver IP address in the Receiver field, a Multicast Source IP address in the Source field, and a Group Value in the Group field.
  4. If a device has multiple gateways, select the correct one from the Gateway list, or select any device's interface with IP as the gateway for the end system.

    Tip: To configure the data source, protocol, and other advanced settings for path calculation, click the  icon to make changes. See Path Settings for more reference.

See Predefining Gateway Fix-up Rules for details.

  1. Click the path to start calculating the path. A map is automatically created to diagram the multicast path.
  1. (Optional) Click the icon in the Path Result Pane and select Save Path to save the path to the Path Browser.
