Configure the Socket WAN interface bandwidth according to your account’s license model and the bandwidth you want the site to use. This article applies to both the Enforcement and Bursting license models. For more information about bandwidth licenses, see this article.
The bandwidth available from your ISP can differ from the bandwidth configured for a Socket WAN interface. The interface setting limits the bandwidth that the link can use, it does not increase the capacity provided by your ISP. Configure values that do not exceed the available ISP link bandwidth, and consider the following guidance for your license model.
Enforcement Licenses
For accounts using the Enforcement license, the site license provides the total bandwidth capacity across all active WAN links, separately for upstream and downstream traffic. For example, a 1000 Mbps site license provides up to 1000 Mbps download and 1000 Mbps upload across all active links, rather than 1000 Mbps per active link.
Active/Active: Configure the bandwidth for each active link so that the combined downstream values and the combined upstream values are within the site’s licensed capacity. For example, with a 1000 Mbps site license and two active links, you can configure each link for 500 Mbps upstream and downstream, provided each ISP link supports these values. You can also use an unequal allocation according to each link’s bandwidth and your site requirements.
Active/Passive: You can configure both the active and passive links for the full site bandwidth, subject to each ISP link’s bandwidth. For example, with a 1000 Mbps site license, you can configure each link for 1000 Mbps upstream and downstream. The passive link provides replacement capacity after failover and does not add to the site’s licensed capacity.
If a link’s bandwidth is higher than the site’s licensed capacity, traffic that exceeds the site license is discarded. Configuring a higher interface bandwidth does not increase the site’s licensed capacity.
If your site license includes global and regional bandwidth, use the total bandwidth (global + regional) as the site’s licensed capacity when allocating bandwidth to the links.
For more information, see Calculating Bandwidth License Capacity.
Bursting Licenses
For accounts using Bursting licenses, set the Socket WAN interface bandwidth according to the usage you want to pay for. For example, if your ISP link provides more bandwidth than you intend to use, configure a lower interface bandwidth to match your intended usage.
Updating the Interface Bandwidth
For links that are dedicated to off-cloud or Alt WAN traffic, this is not part of the site bandwidth license, and set the link to the actual last-mile bandwidth.
Note: For sites with multiple links, follow the procedure below for each link.
To update the Socket WAN interface bandwidth:
From the navigation menu, select Network > Sites, and select the site.
From the navigation menu, select Site Configuration > Socket.
Select the Socket Interface. The Edit Socket Interface panel opens.
In Bandwidth, enter the new Downstream Mbps and Upstream Mbps values. Configure these values according to the guidance for your license model above.
You can set values as whole numbers or include up to one decimal.
Click Apply, and then click Save.
