Defining performance SLA

Create performance SLA to measure the health of VPN tunnels and WAN links.

Following is an overview of the procedure:

1. Create performance SLA for VPN tunnels to monitor underlay links. See Defining VPN performance SLA.
2. Create performance SLA for WAN links to monitor the overlay. See Defining WAN performance SLA.

Defining VPN performance SLA

Create performance SLA to measure the health of VPN tunnels to monitor overlay links.

To configure VPN performance SLA:

1. Go to Network > SD-WAN > Performance SLAs, and click Create New.
2. Set the following options:
   1. Set Name to HQ_VPN.
   2. Set Server to 10.1.0.1.
   3. Set Participants to Specify, and select WAN1-VPN, WAN2-VPN.
3. Enable SLA Target, and set the following options:
   1. Set Latency threshold to 100 ms.
   2. Set Jitter threshold to 25 ms.
   3. Set Packet Loss threshold to 1 %.
4. In the Link Status section, set the following options:
   1. Set Failures before inactive to 3.
   2. Set Restore link after to 3.
5. Click OK.

Defining WAN performance SLA

Create performance SLA to measure the health of WAN links to monitor underlay links.

To configure WAN performance SLA:

1. Go to Network > SD-WAN > Performance SLAs, and click Create New.
2. Set the following options:
   1. Set Name to Internet.
   2. Set Server to 1.1.1.1.
   3. Set Participants to Specify, and select ISP1, ISP2.
3. Enable SLA Target, and set the following options:
   1. Set Latency threshold to 250 ms.
   2. Set Jitter threshold to 55 ms.
   3. Set Packet Loss threshold to 1 %.
4. In the Link Status section, set the following options:
   1. Set Failures before inactive to 3.
   2. Set Restore link after to 3.
5. Click OK.
