Configuring Dynamic Mesh Tunnel Thresholds for all Tenants

 

CSO dynamically creates or deletes a mesh tunnel (that does not pass through an enterprise hub or a provider hub) between two branch sites, if:

  • The number of sessions closed between two branch sites crosses the threshold value.

  • The WAN links of the two branch sites have matching mesh tags.

For more information on dynamic mesh tunnels, see Dynamic Mesh Tunnels Overview.

Note
  • Changes made to the dynamic mesh threshold values are not applicable to existing tenants. Changes are applicable only to tenants that are added after the threshold values are modified.

  • You can also modify the threshold values while adding a tenant. The threshold values that you specify on the Add Tenant page (for a specific tenant) override the threshold value previously configured for all tenants.

  • Sites with the Secure SD-WAN Essentials service do not support creation or deletion of dynamic mesh tunnels based on a user-defined threshold for the number of sessions closed between two branch sites.

To modify dynamic mesh threshold values for all tenants:

  1. Select Administration > Dynamic Mesh.

    The Dynamic Mesh page appears.

  2. Complete the configuration according to the guidelines in Table 1.Note

    Fields marked with * are mandatory.

  3. Click Save.

    A confirmation message appears indicating that the threshold values are saved and you are returned to the Dynamic Mesh page.

Description

Threshold for Creating a Tunnel

Number of Sessions

For creating dynamic mesh tunnels, specify the number of sessions closed (for a duration of 2 minutes) between two branch sites.

If the number of sessions closed (for a duration of 2 minutes) is greater than or equal to the value that you specified, a dynamic mesh tunnel is created between two branch sites.

The default threshold value (the number of sessions closed for 2 minutes) is 5.

For example, if you specify the number of sessions closed as 10, dynamic mesh tunnels are created if the number of sessions closed between two branch sites in 2 minutes is greater than or equal to 10.

Threshold for Deleting a Tunnel

Number of Sessions

For deleting dynamic mesh tunnels, specify the number of sessions closed (for a duration of 15 minutes) between two branch sites.

If the number of sessions closed (for a duration of 15 minutes) is lesser than or equal to the value that you specified, a dynamic mesh tunnel is deleted between two branch sites.

The default threshold value (the number of sessions for 15 minutes) is 2.

For example, if you specify the number of sessions closed as 5, dynamic mesh tunnels are deleted if the number of sessions closed between two branch sites in 15 minutes is lesser than or equal to 5.
