This article addresses the most frequently asked questions (FAQ) and know errors about fallback connections (failover).

FAQ

When does the edge gateway switch to a fallback connection and back?

When the preferred connection is unavailable, the edge gateway will automatically switch to its 1st fallback connection. When the 1st fallback connection is unavailable as well, the 2nd fallback connection will be used. When a higher priority connection is back up, the edge gateway will automatically switch back to that connection.

Under certain conditions, the SecureEdge and SecureEdge Pro models may use a fallback connection even when a higher priority connection is available. This is based on the IPv6 availability on each configured connection and the unpredictable response order of the used DNS server. If you're experiencing issues as the result of this, please let us know.

The edge gateway constantly checks each configured connection to determine whether that connection is available or not. The exact method differs per edge gateway model. If your edge gateway cannot connect, meaning it may not be able to determine whether the connection is available, make sure the network firewall does not block the edge gateway's method. For more information, see How does your device connect to the IXON Cloud?.

SecureEdge and SecureEdge Pro method

Method: HTTP request to our domain http://nmc.ayayot.com:443/ , expecting a "204 No content" with a specific header as response. This cannot be changed.
Interval: Every 60 seconds. This cannot be changed.

The HTTP request needs to only fail once for the connection to be considered unavailable. The same goes for it to be considered available again.

IXrouter3 method

Method: Ping (ICMP) message to publicly available IP addresses. These are configurable, but can generally be left to their default values, see tracking settings below.
Interval: Every 5 seconds. This is configurable, but can generally be left to its default value, see tracking settings below.

The ping message needs to fail several consecutive times for the connection to be considered unavailable. The same goes for it to be considered available again.

Can I configure failover immediately when I register my edge gateway?

Yes, there are different methods to achieve this.

Usually, users first register their edge gateway and then later add fallback connections through the IXON Cloud, as explained in the support article.
Applying a template when you activate your edge gateway is slightly simpler, because you don't have to enter each connection's details, that's already in the template.
- The support article explains the use of templates after an edge gateway is already activated. You can also select a template in the edge gateway activation window to immediately apply the template upon activation.
You can also automatically apply a template upon registration with use of registration profiles.
Alternatively, you can also create a configuration file that immediately configures fallback connections once the USB stick with the configuration file is inserted into the edge gateway. Simply download the configuration of an existing edge gateway with the desired fallback connections configured.
1. Go to Fleet Manager > Devices and click on your device name.
2. Open the sync optionsand select Download config file.
