Hi,
We are using the Harmonic NMX connector 4.2.0.x.
In the documentation for older ranges, there are references to:
“IP address/host: The polling IP of the device or, if redundancy mode is permitted, the primary/backup IP.”
The documentation also mentions that the General page shows primary IP, backup IP, and redundancy status.
However, in our 4.2.0.x setup, we cannot find any place where a backup IP can be configured. Since this range uses HTTP and WebSocket, we are not sure if this redundancy behavior still applies.
Can someone clarify:
-
Does 4.2.0.x still support primary/backup IP at connector level?
-
If yes, where is the backup IP configured?
-
Or does this only apply to the older serial/SNMP-based ranges?
Thanks.
Hi Stefan,
Connector behavior
The IP configuration mentioned in the documentation appears to refer specifically to the polling IP configured in the element’s connection settings.
In practice, the connector communicates with a single configured IP address. Based on what I could verify, I did not find any native support in the 4.2.0.x (HTTP/WebSocket-based) connector for defining both a primary and a backup IP address, nor any built-in mechanism to switch automatically between nodes in a 1+1 Hot Standby setup.
Monitoring and redundancy
Although the connector itself does not appear to manage failover, the element’s General page can still display the current redundancy state, such as master/slave.
For seamless monitoring, the recommended approach is to use a Virtual IP (VIP) that moves between the active and standby nodes. By configuring the DataMiner element to connect to this VIP, polling can continue against the currently active node without requiring manual intervention.
Does this help you move forward with the setup?
Kind regards,
Robin
