Configuring the Communication Intervals

Oct 28, 2016
The hello interval is the interval at which the heartbeat messages are sent to the peer node. The dead interval is the time interval after which the peer node is marked DOWN if heartbeat packets are not received. The heartbeat messages are UDP packets sent to port 3003 of the other node in an HA pair. Dead interval must be set as a multiple of hello interval.

To set the hello and dead intervals by using the command line interface

At the command prompt, type:

  • set HA node [-helloInterval <msecs>] [-deadInterval <secs>]
  • show HA node <id>

To set the hello and dead intervals by using the configuration utility

  1. Navigate to System > High Availability and, on the Nodes tab, open the node.
  2. Set the following parameters:
    • Hello Interval (msecs)
    • Dead Interval (secs)
