Configure Automatic Bandwidth Monitoring

Configure Automatic SD-WAN Bandwidth Monitoring Using Versa Director

1. Configure a Versa speed-test server. Typically, in a hub-and-spoke topology, you configure the hub as the speed-test server. For more information, see Configure a Versa Speed-Test Server.
2. In Director view:
   1. Select the Configuration tab in the top menu bar.
   2. Select Templates > Device Templates in the horizontal menu bar.
   3. Select an organization in the left navigation bar.
   4. Select a post-staging template in the main pane. The view changes to Appliance view.
3. Select the Configuration tab in the top menu bar.
4. Select Services > SD-WAN > Site in the left menu bar. The main pane displays the Site pane.
   
   
5. In the Site pane, click the Edit icon. The Edit Site popup window displays.
6. In the Group Membership field, click the  Add icon, and then enter a name for the group to which to assign the Versa speed test servers. You configure group membership only on the device that is acting as the speed-test server. Note that if a spoke is using two hubs to perform automatic SD-WAN bandwidth measures, you must select a hub-specific group membership name.
   
   
7. Click OK.

On the spoke device, you configure the SD-WAN path policy to apply to branches, hubs, and Controller devices:

1. In Director view:
   1. Select the Configuration tab in the top menu bar.
   2. Select Templates > Device Templates in the horizontal menu bar.
   3. Select an organization in the left navigation bar.
   4. Select a post-staging template in the main pane. The view changes to Appliance view.
2. Select the Configuration tab in the top menu bar.
3. Select Services > SD-WAN > Path Policies. The main pane displays the path policies that are currently configured.
   
   
4. Click the  Add icon. The Add Path Policy popup window displays.
   
   
5. In the Policy Name field, enter a name for the policy.
6. Click the  Add icon. The Add Terms window displays.
7. Select the Match tab, and then enter information for the following fields.
   
   
    

   Field	Description
   Term Name (Required)	Enter a name for the term.
   Remote Site Type	Select a remote site type with which to conduct the speed test.
   Group Membership	Click the  Add icon and select the remote node group.
   Circuit Names (Tab)	Configure the WAN circuits to match, by circuit name.
   Local	Click the  Add icon. From the drop-down, select a WAN circuit name on the local branch. Circuits typically have names such as WAN1 and WAN2.
   Remote	Click the  Add icon. From the drop-down, select a WAN circuit name on the remote branch.

8. Select the Action tab, and then enter information for the following fields.
   
   
    

   Field	Description
   Bandwidth Monitoring	Click to monitor the link bandwidth on a circuit. You can view the circuit bandwidth in the Monitor > Summary screen.
   Interval	Enter how often to monitor the link bandwidth, in minutes. Range: 10 through 300 minutes Default: 10 minutes

9. Click OK.

Then, associate the path policy with an interface:

1. In Director view:
   1. Select the Configuration tab in the top menu bar.
   2. Select Templates > Device Templates in the horizontal menu bar.
   3. Select an organization in the left navigation bar.
   4. Select a post-staging template in the main pane. The view changes to Appliance view.
2. Select the Configuration tab in the top menu bar.
3. Select Services > SD-WAN > System > Site in the left menu bar. The main pane displays the Site pane.
   
   
4. In the Site pane, click the  Edit icon. The Edit Site popup window displays.
   
   
5. In the WAN Interfaces table, select an interface. The Edit WAN Interfaces popup window displays.
6. In the Bandwidth Monitoring Policy field, select the policy to associate with the WAN interface.
   
   
7. Click OK.

Configure Automatic SD-WAN Bandwidth Monitoring Using a REST API Call

Use this API call to enable automatic SD-WAN based bandwidth monitoring.

The following example shows the payload of this API call:

{ 
   "path-policy":[ 
      { 
         "policy-name":"BW-MS-WAN1",
         "terms":{ 
            "term":[
               { 
                  "term-name":"Test-BW-MS",
                  "match":{
                     "remote-site-type":"branch"
                  },
                  "action":{
                     "sla-monitoring":{
                        "interval":"10000",
                        "logging-interval":"300",
                        "loss-threshold":"3"
                     },
                     "bandwidth-monitoring":{
                        "interval":"10"
                     }
                  }
               }
            ]
         }
      }
   ]
}

Use this API call to associate the path policy to an interface.

The following example shows the payload of this API call:

"wan-interfaces":{
         "vni":[ 
            { 
               "name":"vni-0/0.0",
               "sla-monitoring-policy":"SLAM_Policy_vni-0/0.0",
               "bandwidth-monitoring-policy":"BW-MS-WAN1",
               "shaping-rate":{
 
               },
               "management-traffic":{
                  "priority":"0"
               }
            },
            { 
               "name":"vni-0/1.0",
               "sla-monitoring-policy":"SLAM_Policy_vni-0/1.0",
               "shaping-rate":{
 
               }
            }
