WAN Profiles

While the CommBox EdgeOS System is installed on the site, a default WAN Profile is created with the priority of the enabled WANs configured in this WAN Profile and assigned to the default Access Network. However, user can create multiple WAN profiles of their choice.

WAN Profile Types

There are multiple profile options available, such as Strict Priority and Bonding.

Strict Priority

This is a configuration where WAN links are arranged in a priority order where there is never more than one WAN link for a given priority.

Bonding

It is possible to configure any individual VLAN, subnet or even device in a way that the Internet traffic that entity is carried by more than one WAN link, based on conditions. This feature is called bonding, and the set of WAN links is called the ‘bonded set’. Within WAN profiles, if any priority levels contain more than one WAN link, then those links in that priority level form a bonded set. It should be noted that, should any one link in a bonded set fail, while new TCP or UDP sessions would be assigned to one of the surviving links of the bonded set, any sessions currently using that failed link will be lost.

Creating a new WAN Profile

To create a WAN profile, perform the following steps.

Select the SDWAN option from the side bar. The WAN Profiles tab will be selected by default.

Initially, the Default WAN profile is available. User can create multiple profiles. Once, the profiles are configured, the profiles become available on the WAN Profiles page. They can associate the WAN profile with Access Networks.

To create a WAN Profile, click + Profile. The Profile Name field becomes available under the Create Internet (WAN) Profile section. To enter data in the respective fields, see table below.

Fields	Description
Profile Name	Enter the name of the profile.
Fall-Through Mode	Fall-Through Mode controls traffic behavior when the MPK tunnel is unavailable. Enabled: Traffic is routed natively over the WAN. Disabled: Traffic is dropped until the tunnel is restored.
Disabled WANs	Disabled WAN sources are displayed.
Set Priority of Enabled WANs
Highest Priority	To assign WAN links/Interfaces to a priority level, perform the following steps. Note: Only Interfaces enabled on the Interfaces tab will be visible on the WAN Profile screen. Steps Drag and drop the WANs available from the Disabled WANs section to the respective priority section. More than one WAN (similar or dissimilar type) can be associated with a single priority. In this case, these WANs will be bonded. Note: Interfaces/WANs for which Probe Configuration Profile is set to Always Up or High Cost cannot be bonded with other Interfaces/WANs. Link Bonding can be set to Static or Dynamic. By default, the link bonding type is Dynamic, in which case the system distributes the traffic on each WAN link based on performance. In Static Setting, a configured % of traffic is set for each WAN link. For details of the types of link bonding, point to i icon next to the Link Bonding. The user can configure the weighting % of the WAN link. To configure the weighting %, perform the following steps. Steps Click Dynamic under the link bonding section. The Bonding Mechanism pop-up window appears. Refer to Figure Bonding Mechanism. Click Static. The Weighting % (applicable for Static Bonding) section becomes available. The Bonding Mechanism pop-up window appears. Refer to Figure Static Bonding Mechanism. Enter the weighting % for the WAN links. User must ensure that the sum of the weighting % for all WAN links must be 100%. Below is an example of the like WAN links bonding. User can configure 40 as the weighting % for the Cell 1 and 60 as the weighting % for the Cell 2. As, sum of both weighting % (40 + 60) = 100. Below is an example of the unlike WAN links bonding. User can configure 40 as the weighting % for the VSAT1, 30 as the weighting % for the Cell 1, and 30 as the weighting % for the Cell 2, hence the sum of weighting % (40 + 30 + 30) = 100. Click Done. The WAN Profile is created and updated in the left table. In case of trying to bond WANs with probe configuration profile set to ‘Always Up’ or ‘High Cost’, an error message is displayed.
Priority 2	Refer to Highest Priority
Priority 3	Refer to Highest Priority
Priority 4	Refer to Highest Priority
Lowest Priority	Refer to Highest Priority
Hub Dropoff	Hub Dropoff determines how a WAN link is treated when it loses connectivity to the SD-WAN hub, even if the physical internet link remains active. This setting prevents traffic from using a WAN that cannot reach the hub and ensures proper failover behavior. Hub Dropoff can be enabled/disabled per WAN. When Hub Dropoff is enabled for a WAN: If the WAN cannot reach the SD-WAN hub, the WAN is removed from active use Traffic is redirected to the next available WAN based on priority (if fall-through is enabled) When Hub Dropoff is disabled: The WAN remains active as long as the physical link is up Traffic may continue to use the WAN even if hub connectivity is lost
Link Bonding	Link Bonding allows multiple WAN links to be used together to distribute traffic, improving bandwidth utilization and overall network performance. Instead of sending all traffic through a single WAN, Link Bonding spreads traffic across selected WAN links based on the configured bonding mode. Link Bonding can be configured in Static or Dynamic mode. Dynamic Link Bonding: Traffic is automatically distributed across bonded WAN links Distribution is based on real-time link performance, such as latency, loss, and availability Ensures optimal usage of the best-performing links Recommended for most deployments where WAN conditions vary. Static Link Bonding A fixed percentage of traffic is assigned to each bonded WAN link Traffic distribution remains constant regardless of link conditions Suitable when WAN links have known, stable capacities
Internet Priority (DL/UL MIR)	Internet Priority allows you to define bandwidth limits per WAN link within an Internet (WAN) profile. It controls how much download (DL) and upload (UL) bandwidth a specific WAN is allowed to use when handling traffic. Click the icon. Enter the Download MIR. This is the maximum download speed (in Mbps) allowed on this WAN. Enter the and Upload MIR in mbps. The maximum upload speed (in Mbps) allowed on this WAN. Together, these values cap the bandwidth that traffic can use on the selected WAN. Internet Priority is applied per WAN link. This feature is useful when you want to: Prevent a WAN from consuming excessive bandwidth Control usage on metered or expensive links (LTE, VSAT, Satellite) Ensure fair distribution of bandwidth across multiple WANs

Table WAN Profile

Once the WAN link is assigned to the priority levels, the server will verify the network based on the priority levels. As an example, the user can set the following priority levels of enabled WANs for Owner Profile.

Highest Priority – Ethernet

Priority 2 – Cell1 and Cell2

Priority 3 – VSAT 1 and VSAT 2

Initially, the server will verify whether the Ethernet network is available as the Ethernet is assigned the highest priority. If the Ethernet network is available, then the internet connection will be established through this network. Otherwise, the server will verify whether the Cellular network is available as the Cellular networks are assigned the priority 2 level. The process will continue up to the priority level configured.

The server will distribute the traffic based on the weighting % configured for the WAN links.

Click Save.

WAN profile is configured successfully and visible on the table listing on the left. The WAN profile will become available while configuring the networks, see figure below.
