Manage ports in bridge

◀ Go back to main README

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 and add a scheduler to start with default setup on system startup:

$ScriptInstallUpdate global-wait;
/ 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.
