.. conf_master:: ping_on_rotate
``ping_on_rotate``
------------------
.. versionadded:: 2014.7.0
Default: ``False``
By default, the master AES key rotates every 24 hours. The next command
following a key rotation will trigger a key refresh from the minion which may
result in minions which do not respond to the first command after a key refresh.
To tell the master to ping all minions immediately after an AES key refresh, set
ping_on_rotate to ``True``. This should mitigate the issue where a minion does not
appear to initially respond after a key is rotated.
Note that ping_on_rotate may cause high load on the master immediately after
the key rotation event as minions reconnect. Consider this carefully if this
salt master is managing a large number of minions.
