The number of times to retry a unicast request to a SNTP server
that has not successfully responded. This retry count is
used for directed SNTP requests in anycast(4) operational mode.
For example, assume this object has been SET to a value of 2.
When the SNTP client queries the bound server it will send 1
SNTP request frame. If that original attempt fails, the
client will retry up to a maximum of 2 more times before
giving up and unbinding from the server. Once the client
becomes unbound it will start sending out anycast bind
requests at an interval specified by
etsysSntpClientAnycastBindRequestInterval. Maintaining the
value of this object across agent reboots is REQUIRED.
