iQuery Connectivity timeout

When the network is unstable, there will be an alarm to leave the synchronization group. What is the timeout

  • Look at the "BIG-IP monitor settings" as this is the monitor that uses iquery for checking F5 devices and gatherig statistics from the LTM devices about the availability of their VIP. As a note the probe timeout for the dns/gtm big-ip monitor is 3 seconds and it was cofigurable in older versions but in newer it is not as 3 seconds is plently of time for the other F5 device to return reply to a probe request.
