    <title>Description</title>

    <para>

      firewall-cmd is the command line client of the firewalld daemon. It provides interface to manage runtime and permanent configuration.

    </para>

    <para>

      The runtime configuration in firewalld is separated from the permanent configuration. This means that things can get changed in the runtime or permanent configuration.

    </para>

  </refsect1>

  <refsect1 id="options">

    <title>Options</title>

    <para>

      Sequence options are the options that can be specified multiple times, the exit code is 0 if there is at least one item that succeeded. The <literal>ALREADY_ENABLED</literal> (11), <literal>NOT_ENABLED</literal> (12) and also <literal>ZONE_ALREADY_SET</literal> (16) errors are treated as succeeded.

      If there are issues while parsing the items, then these are treated as warnings and will not change the result as long as there is a succeeded one.

      Without any succeeded item, the exit code will depend on the error codes. If there is exactly one error code, then this is used. If there are more than one then <literal>UNKNOWN_ERROR</literal> (254) will be used.

    </para>

    <para>

      The following options are supported:

	      Check whether the firewalld daemon is active (i.e. running). Returns an exit code 0 if it is active, <replaceable>RUNNING_BUT_FAILED</replaceable> if failure occurred on startup, <replaceable>NOT_RUNNING</replaceable> otherwise.

	  <listitem>

	    <para>

	      Reload firewall rules and keep state information.

	      Current permanent configuration will become new runtime configuration,

	      i.e. all runtime only changes done until reload are lost with reload

	      if they have not been also in permanent configuration.

	    </para>

	    <para>

	      Note: Runtime changes applied via the direct interface are not

	      affected and will therefore stay in place until firewalld daemon

	      is restarted completely.

	  <term><option>--complete-reload</option></term>

	  <listitem>

	    <para>

	      Reload firewall completely, even netfilter kernel modules. This will most likely terminate active connections, because state information is lost. This option should only be used in case of severe firewall problems. For example if there are state information problems that no connection can be established with correct firewall rules.

	  <listitem>

	    <para>

	      Save active runtime configuration and overwrite permanent configuration with it.

	      The way this is supposed to work is that when configuring firewalld you do runtime changes only and

	      once you're happy with the configuration and you tested that it works the way you want, you save

	      the configuration to disk.
