This section describes how to configure and deploy SD-WAN for the first time. 

To configure and deploy SD-WAN in your network for the very first time, select SD-WAN under Configuration Menu in the EdgeMarc VOS. The SD-WAN page is displayed and the status tab
appears by default.

SD-WAN Status Tab

Stateful SIP Transfer

The Stateful SIP Transfer is a feature for voice calls. This enhancement enables WAN link failover during an ongoing voice call, ensuring that the call is not disrupted during the WAN link switch. There is a seamless movement of the SIP session from one WAN link to another when primary link quality has degraded.

  1. Go to Stateful SIP Transfer and successively configure the settings, as mentioned below.

    • SIP Server Configuration
      Click the SIP page link on the Stateful SIP Transfer tab. The SIP Settings page appears. Here, configure the SIP Server Address.

    • Enable WAN Link Redundancy
      Click the WAN Link Redundancy link on the Stateful SIP Transfer tab. The WAN Link Redundancy page appears. Enable both WAN Link Redundancy and Dual WAN Ports.

    • Configure Secondary Interface
      Click the Secondary WAN link on the Stateful SIP Transfer tab. The Secondary WAN Interface Settings page appears. Configure the Secondary WAN Interface according to your network setup.


    • Configure VoIP Settings
      On the VoIP page, enable Route all SIP signalling through B2BUA.


  2. Once the configuration changes are made, an option to enable Stateful SIP Transfer appears on the Stateful SIP Transfer tab.

  3. Enable Stateful SIP Transfer. A detailed configuration menu appears. The tooltip adjacent to each parameter provides a quick help for configuring each parameter.


    For more details on Stateful SIP Transfer configuration, refer to Stateful SIP Transfer Settings.

Note

Stateful SIP Transfer and Survivability are not used in tandem. When Stateful SIP Transfer is enabled, disable Survivability. Similarly, HA does not work when Stateful SIP Transfer is enabled.


Business Policy

Business Policy enables traffic prioritization. Business Policy rules allow data flow to be classified based on URL, IP Address or destination port.

  1. On the Business Policy tab, an option to enable Business Policy appears.

  2. Select the Enable Business Policy check-box and click the Submit button to enable Business Policy. Once the business policy is enabled successfully, a detailed configuration menu appears.


    For more details on Business Policy configuration, refer to Business Policy.

    Note

    Business Policy and Fastpath Hardware Acceleration cannot be enabled in tandem. Also, Fastpath Hardware Acceleration is available only on EdgeMarc 4800 devices.

Advanced

On the Business Policy - Advanced page, configure the settings as mentioned on the page. Business Policy - Advanced page prompts you to enable the Traffic Shaper. Go to the Traffic Shaping page and enable Traffic Shaping. The Business Policy - Advanced page is displayed.

Note

Enable Traffic Shaping before enabling Business Policy. If Traffic Shaping is already enabled, the prompt to enable it is not displayed.

To know more about configuring the Advanced Business Policy page, refer to Business Policy - Advanced

Once the Stateful SIP Transfer, Business Policy and Advanced Business Policy settings are configured, go back to the SD-WAN status tab. The Stateful SIP Transfer and WAN Link Redundancy status are Running, and the Primary Link and Secondary Link status are Available.
