Starting in version 2.10.4 of eKeypad all configurable systems can include an optional failover address and port.
This feature can be very tricky to verify and setup correctly. It is advised that you get help from eKeypad support if you have any questions. If you do not have a working knowledge of computer networking it is also advised that you seek the help of a local expert. Very few setups need the failover features in eKeypad. There are alternate methods that typically work better than a failover configuration. Make sure you really need it before taking the time and effort to properly setup failover.
The dynamic nature of mobile devices makes failover a useful tool but no single method will work in all scenarios. eKeypad includes two failover methods. You will need to look at how you use eKeypad and select the method that best suits your needs.
Details of failover methods
- Connection Timeout. Using this method, eKeypad will attempt to make a connection using the primary network address/port and if it receives a timeout error will attempt to use the alternate address/port before reporting any error messages. The disadvantage of this method is the time required to connect to your system can take much longer. 30-60 seconds in extreme scenarios.
- Attempt to Detect. Using this method, eKeypad will compare the primary network address/port against the current network address of your mobile device. If it appears your device is on the same address as the primary address/port eKeypad will use this address, if not eKeypad will use the alternate address/port. The disadvantage of this method is that it is not always possible to accurately determine of your mobile device is on the same network as your systems. If this check fails you will not be able to connect to your system temporarily.
It is important to test failover connections thoroughly. At a minimum you should make sure the configuration works on your local Wifi and via cellular data. Testing on the most common remote Wifi networks you will be using is also advisable to ensure the failover setup works as expected.
