+Manage ports in bridge
+======================
+
+[◀ Go back to main README](../README.md)
+
+Description
+-----------
+
+These scripts are supposed to handle interfaces and switching them from
+one bridge to another.
+
+Requirements and installation
+-----------------------------
+
+Just install the scripts:
+
+    $ScriptInstallUpdate bridge-port-to-default,bridge-port-toggle;
+
+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;
+
+There is also global configuration:
+
+* `BridgePortTo`: specify the configuration to be applied by default
+
+Install [global-wait](global-wait.md) and add a scheduler to start with
+default setup on system startup:
+
+    / system scheduler add name=bridge-port-to-default on-event="/ system script { run global-wait; run bridge-port-to-default; }" start-time=startup;
+
+Usage and invocation
+--------------------
+
+The usage examples show what happens with the configuration from above.
+
+Running the script `bridge-port-to-default` applies all configuration given
+with `default=`:
+
+    / system script run bridge-port-to-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 script `bridge-port-toggle` toggles to configuration given
+with `alt=`:
+
+    / system script run bridge-port-toggle;
+
+* 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 script `bridge-port-toggle` again toggles back to configuration
+given with `default=`.
+
+More configuration can be loaded by setting `BridgePortTo`:
+
+    :set BridgePortTo "extra";
+    / system script run bridge-port-to-default;
+
+* Interfaces `en1` and `en2` are unchanged.
+* Interface `en3` is put in bridge `br-intern`.
+
