Manage ports in bridge

ℹ️️ Info: This module can not be used on its own but requires the base installation. See main README 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:

$ScriptInstallUpdate global-wait;
/system/scheduler/add name=bridge-port-to on-event="/system/script/run global-wait; :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.
