Sets the retry interval for forwarding a DNS query to a
forwarder or resolution exception server. These queries are
recursive, and may require more time for the forwarder to
resolve.
To ensure the server tries all forwarders, set this value to the
'request-expiration-time' divided by one less than the total
number of configured forwarders).
Note: This attribute has no affect when you enable slave-mode;
the server uses slave-forward-retry-time instead.
ha-dns-comm-timeout rangetime(2s-24h) default = 30s
Sets the period of time that must elapse before the server
determines it cannot communicate with its HA DNS partner.
ixfr-enable bool default = enabled
Controls the incremental transfer behavior for zones for
which you have not configured a specific behavior. Required,
true (enable).
ixfr-expire-interval rangetime(0-68y5w3h14m7s) default = 0
Specifies the maximum duration between full zone transfers that
the DNS server will request incremental transfer updates for its
secondary zones. After this time interval expires, even if an
incremental transfer would normally be requested, the DNS server
will instead request a full zone transfer. Setting this value
to 0 does not enforce any time limit between full zone transfers.
local-port-num rangeint(1-65535) default = 53
Specifies the UDP and TCP port number that the DNS server
uses to listen for queries.

Determines which detailed events the DNS server logs, as set
using a bit mask. Logging these additional details can help
analyze a problem. Leaving detailed logging enable for a long
period, however, can fill the log files and cause the loss of
important information.
The possible flags are:
config
This flag will cause log messages pertaining to server
configuration and server de-initialization (unconfiguration).
ddns
This flag will cause the logging of high-level DDNS messages.
Detailed DDNS logging (e.g. RRs that have been deleted or
added) can be enabled via ddns-details.
xfr-in
This flag will allow the generation of log messages
associated with inbound full and incremental zone transfers.
