Advanced Network Configuration feature enables support of critical use-cases seen in Industrial environments

There are three different parameters in the advanced network configuration that enable the above features -

  • L2 Tunnelling - for automatically creating Layer-2 tunnel endpoints for both VXLAN and GRE protocols.

    • Bridge - for bridging the traffic to and from devices behind the Layer-2 tunnel

  • IP Multicasting - for pushing the multicast traffic similar to Layer-2 traffic through a tunnel

  • Supernetting - for enabling routing, for the devices behind supernet hosts.

These parameters can be configured via templates per edge cluster, and applied as network policies to specific device groups to enable the above-mentioned features.

Creating an advanced network config template

  • These templates can be created on an Edge Cluster details page, as long as the edge is running a version of 2305 or higher.

  • Navigate to the end of the page and click the Add Advanced Network Config button to open up the form

  • Give a name for your template (mandatory field)

  • Enable Bridge mode and select Tunnel Type (GRE or VXLAN)

    • If a specific Tunnel Type is not chosen, GRE will be chosen by default

  • Specify a VLAN ID (a valid number between 1 to 4094)

  • Enable Supernetting and specify one or more subnet masks.

    • Subnet masks must hold the following format: a.b.c.d/e.f.g.h (where a, b, c, d, e, f, g, h are each numbers between 0 to 255) adhering to the IPv4 notation

  • Multiple subnet masks can be added by clicking on the “+” icon next to the Subnet Mask field input

  • Once you click Create at the end of the form, you should see a success message with a green banner denoting that the advanced configuration has been successfully created, and the table should reflect your new template.

Applying advanced network config to a device group

  • Navigate to the Device Groups page and click on Create New to create a new device group

  • To create a device group, provide a

    • Name (mandatory field)

    • One or more devices

    • IP Domain (mandatory field)

      • It is set to “default” if nothing is specified

  • To apply an advanced network config to the device group, select an edge cluster and the corresponding advanced network configuration templates will appear

    • Please note that the Advanced Network Config field will only be displayed if an external IP domain is selected in the previous field

Editing/Removing advanced network config from a device group

  • To edit/remove an applied advanced network configuration from a device group, click on the 3-dot menu, followed by the Edit button to launch the edit device group workflow.

  • Select another template or mark the field as None to remove the associated configuration

Editing/Deleting an advanced network config template

  • Once an advanced network configuration has been successfully created, you can edit or delete the config and associated parameters from the edge cluster details page, using the 3-dot menu at the last column of the config table

Note: Please note that applying, editing or removing an advanced network configuration to a device group may result in network downtime so we recommend doing this during a maintenance window.

The same applies for editing the parameters of an advanced network config template which is already in use by one or more device groups.
