+Manage ports in bridge
+======================
+
+[◀ Go back to main README](../README.md)
+
+🛈 This module can not be used on its own but requires the base installation.
+See [main README](../README.md) for details.
+
+Description
+-----------
+
+This module and its functio are are supposed to handle interfaces and
+switching them from one bridge to another.
+
+Requirements and installation
+-----------------------------
+
+Just install the module:
+
+    $ScriptInstallUpdate mod/bridge-port-to;
+
+Configuration
+-------------
+
+The configuration goes to ports' comments (`/ interface bridge port`).
+
+    / interface bridge port add bridge=br-guest comment="default=dhcp-client, alt=br-guest" disabled=yes interface=en1;
+    / interface bridge port add bridge=br-intern comment="default=br-intern, alt=br-guest" interface=en2;
+    / interface bridge port add bridge=br-guest comment="default=br-guest, extra=br-extra" interface=en3;
+
+Also dhcp client can be handled:
+
+    / ip dhcp-client add comment="toggle with bridge port" disabled=no interface=en1;
+
+Add a scheduler to start with default setup on system startup:
+
+    / system scheduler add name=bridge-port-to on-event=":global GlobalFunctionsReady; :while (\$GlobalFunctionsReady != true) do={ :delay 500ms; }; :global BridgePortTo; \$BridgePortTo default;" start-time=startup;
+
+Usage and invocation
+--------------------
+
+The usage examples show what happens with the configuration from above.
+
+Running the function `$BridgePortTo` with parameter `default` applies all
+configuration given with `default=`:
+
+    $BridgePortTo default;
+
+For the three interfaces we get this configuration:
+
+* The special value `dhcp-client` enables the dhcp client for interface `en1`. The bridge port entry is disabled.
+* Interface `en2` is put in bridge `br-intern`.
+* Interface `en3` is put in bridge `br-guest`.
+
+Running the function `$BridgePortTo` with parameter `alt` applies all
+configuration given with `alt=`:
+
+    $BridgePortTo alt;
+
+* Interface `en1` is put in bridge `br-guest`, dhcp client for the interface is disabled.
+* Interface `en2` is put in bridge `br-guest`.
+* Interface `en3` is unchanged, stays in bridge `br-guest`.
+
+Running the function `$BridgePortTo` with parameter `extra` applies another
+configuration:
+
+    $BridgePortTo extra;
+
+* Interfaces `en1` and `en2` are unchanged.
+* Interface `en3` is put in bridge `br-intern`.
