Issue

Rate-limiting parameter values are too far apart for the Site-to-Site VPN interface of the Routing Domain.

Impact

Site-to-Site VPN performance is affected.

Resolution

Set the Quality of Service (QoS) parameters to the appropriate values (where smaller value greater than or equal to 30 percent of the larger value).

Membership in Administrators, or equivalent, is the minimum required to perform these procedures.

To reset the Site-to-Site VPN interface’s QoS parameters

  1. Run Windows PowerShell with Administrative privileges.

  2. Set the QoS parameters to a specific value by running the following Windows PowerShell command.

    Set-VpnS2SInterface –Name <Site-to-Site VPN interface name> -TxBandwidthKbps <number> -RxBandwidthKbps <number>
