SD-WAN with Versa Networks: Frequently asked questions

How do I change the appliance configuration?

On the appliance service monitoring page, click the configuration tab to see the configuration on the appliance that was built from the templates and the bind data. We recommend changes to the appliance be made only as a temporary method of testing or debugging. Before changes are made, take a picture of the appliance configuration to facilitate an easy rollback.
 

How can I check what template is used on a device?

On the appliance service monitoring page, click the template tab to see the associated templates.
 

How do templates get assigned to appliances?

An appliance is assigned to a device group, which defines the device template to use for that group of appliances. The device template defines the service templates that are used with the device template. The object you want to share across templates (i.e. application definitions) can be defined in common objects. The appliance attributes (device bind data) are the values needed for the variables in the templates (i.e. LAN IP, WAN IP).
 

How do I deploy a change to a template?

Click the commit button to deploy the changes. You must select the device template and then select the appliances you wish to deploy the updates to. Click on the eye icon to see the differences in the configurations. After you start the template deployment, you can check on the status from the tasks icon at the top of the Director.
 

How do I make a change to just one appliance and not all of them in a device group?

It is possible to just deploy a change to a single device in a device group for testing or staging of rollouts. If the topology of just one of the devices in the device group changes, then it needs to be moved to a device template (new or existing).

How do I access the appliance?

Configuration, monitoring, and reporting for the appliances is done through the SD‑WAN portal. If you need it, Lumen can provide read only CLI access to the appliances. The appliance CLI is available through the Director, local console port, or local management interface.

How do I see the status and use of the interfaces on the appliance?

On the appliance monitor page look for the CPE interfaces section to see the realtime interface use from the appliance. If you want to see historical data for your WAN circuits, click on the access circuit tab from the appliance analytics page.

How do I see the bandwidth for an SD‑WAN policy at a site?

In the SD‑WAN traffic section of the appliance monitor page you can filter the traffic by the SD‑WAN policy name or by remote site. If you want to see historical data, click on the rules tab on the appliance analytics page.

How do I see bandwidth use by an SD‑WAN application?

On the appliance service monitoring page you can see the active sessions and filter them by application. If you want to see historical data, click on the application tab on the appliance analytics page.

How do I see bandwidth use by user or device?

On the appliance service monitoring page you can see the active sessions and filter the active sessions by application. If you want to see historical data, click on the user tab on the appliance analytics page.

How do I see active sessions for a site?

On the appliance service monitoring page you can filter the active sessions by application. On the SD‑WAN appliance service monitoring page, select the SD‑WAN service, and then the sessions. Click on the eyeball icon in the session count field to filter for session by criteria such as source/destination or application. You’ll see fields from the column filter icon.

How can I see which path is being used for an SD‑WAN policy at a site?

On the SD‑WAN traffic section of the appliance monitor page you can filter the traffic by the SD‑WAN policy name as well as remote site. For detail on the status of individual paths, go to the appliance service monitoring page, select the SD‑WAN service polices item, then click on the eyeball icon to view the status of the policy. Click on the path, then remote appliance, and then detail to see the details about the paths in that policy. The path with the lowest priority will be used. If a path has a SLA violation it will show SLA violated in the priority.

How do I see the settings for an interface of an appliance?

On the appliance service monitoring page, select interfaces, then click the eyeball icon next to the interface. This provides more detail on the CPE interface section of the appliance monitor page.

How do I know the status of my network?

When an appliance has an outage or if a circuit is down, an auto‑ticket will be opened in Control Center. The operations guide will list the auto‑ticketed events and threshold.

‑ Circuit with high utilization

‑ Path down (but not whole circuit)

‑ Path experiencing SLA violation

How do I look at the status of a site?

On the appliance service monitoring page, the CPE interface section shows the interface status and current realtime use for all interfaces. Under the services tab, the SLA paths will show the status of the paths on the SD‑WAN overlay network to another site. It will show the number of FLAPS (state change) and the time of the last flap. Under the services tab, the SLA metrics will show the last measurement for the quality of the path (packet loss/jitter/latency).

How do I test connectivity from a site (i.e. ping)?

On the appliance service monitoring page, click the services tab to see the ARP tables for any interface. On that same page, the tools tab allows you to perform ping, trace routes, and packet captures on any routing instance.

How do look at the routes on the SD‑WAN appliance?

On the appliance service monitoring page, click the services tab to see the routes for any routing instance on the appliance. If there are multiple routes, the active route will be identified with a plus sign. If the route is to another routing instance on the appliance (typically a split tunnel) it will be a 169.x.x.x target. The peering between routing instances can be seen in the interface configuration on the tunnels tab. If a route is across the overlay network to another SD‑WAN appliance, then the next hop will be the management IP of the SD‑WAN appliance. The management IPs can be seen on the appliance list.

How do I reboot a device or restart services?

On the appliance service monitoring page, click the Administration tab, then select Operations.

How do I check the classification for a URL?

On the appliance service monitoring page, click the configuration tab, then click objects, then pre-defined objects, then URL categories, and then click on the lookup icon.

How do I check the security package update history on an appliance?

On the appliance service monitoring page, click the services tab, click NGFW, and then click security packages.

How do I request SD-WAN training?

You’ll need to open a support ticket and complete the form to request training.

How do I make a change to my SD-WAN service?

You’ll need to open a change request ticket and complete the form to make changes.

How will I know when a ticket is created and updated?

You will receive an email from Lumen letting you know that a ticket has been created. And you will receive additional emails when updates have been made.

After a ticket is opened, what are the next steps for the support team?

You will receive an email from Lumen confirming we have received your request.
