🛈 This module can not be used on its own but requires the base installation.

Description
|
|
|
|
|
-----------
|
|
|
|
|
|
|
|
|
|
This module and its function are supposed to handle VLANs on bridge ports.
|
|
|
|
|
|
|
|
|
|
Requirements and installation
|
|
|
|
|
-----------------------------
|
|
|
|
|
|
|
|
|
|
Just install the module:
|
|
|
|
|
|
|
|
|
|
$ScriptInstallUpdate global-functions.d/bridge-port-vlan;
|
|
|
|
|
|
|
|
|
|
Configuration
|
|
|
|
|
-------------
|
|
|
|
|
|
|
|
|
|
Using named VLANs you have to add comments in bridge vlan menu:
|
|
|
|
|
|
|
|
|
|
/ interface bridge vlan add bridge=bridge comment=intern tagged=br-local vlan-ids=10;
|
|
|
|
|
/ interface bridge vlan add bridge=bridge comment=geust tagged=br-local vlan-ids=20;
|
|
|
|
|
/ interface bridge vlan add bridge=bridge comment=extra tagged=br-local vlan-ids=30;
|
|
|
|
|
|
|
|
|
|
The configuration goes to ports' comments (`/ interface bridge port`).
|
|
|
|
|
|
|
|
|
|
/ interface bridge port add bridge=bridge comment="default=dhcp-client, alt=guest" disabled=yes interface=en1;
|
|
|
|
|
/ interface bridge port add bridge=bridge comment="default=intern, alt=guest, extra=30" interface=en2;
|
|
|
|
|
/ interface bridge port add bridge=bridge comment="default=guest, extra=extra" interface=en3;
|
|
|
|
|
|
|
|
|
|
Also dhcp client can be handled:
|
|
|
|
|
|
|
|
|
|
/ ip dhcp-client add comment="toggle with bridge port" disabled=no interface=en1;
|
|
|
|
|
|
|
|
|
|
Add a scheduler to start with default setup on system startup:
|
|
|
|
|
|
|
|
|
|
/ system scheduler add name=bridge-port-vlan on-event=":global GlobalFunctionsReady; :while (\$GlobalFunctionsReady != true) do={ :delay 500ms; }; :global BridgePortVlan; \$BridgePortVlan default;" start-time=startup;
|
|
|
|
|
|
|
|
|
|
Usage and invocation
|
|
|
|
|
--------------------
|
|
|
|
|
|
|
|
|
|
The usage examples show what happens with the configuration from above.
|
|
|
|
|
|
|
|
|
|
Running the function `$BridgePortVlan` with parameter `default` applies all
|
|
|
|
|
configuration given with `default=`:
|
|
|
|
|
|
|
|
|
|
$BridgePortVlan default;
|
|
|
|
|
|
|
|
|
|
For the three interfaces we get this configuration:
|
|
|
|
|
|
|
|
|
|
* The special value `dhcp-client` enables the dhcp client for interface `en1`. The bridge port entry is disabled.
|
|
|
|
|
* Primary VLAN `intern` (ID `10`) is configured on `en2`.
|
|
|
|
|
* Primary VLAN `guest` (ID `20`) is configured on `en3`.
|
|
|
|
|
|
|
|
|
|
Running the function `$BridgePortVlan` with parameter `alt` applies all
|
|
|
|
|
configuration given with `alt=`:
|
|
|
|
|
|
|
|
|
|
$BridgePortVlan alt;
|
|
|
|
|
|
|
|
|
|
* Primary VLAN `guest` (ID `20`) is configured on `en1`, dhcp client for the interface is disabled.
|
|
|
|
|
* Primary VLAN `guest` (ID `20`) is configured on `en2`.
|
|
|
|
|
* Interface `en3` is unchanged, primary VLAN `guest` (ID `20`) is unchanged.
|
|
|
|
|
|
|
|
|
|
Running the function `$BridgePortVlan` with parameter `extra` applies another
|
|
|
|
|
configuration:
|
|
|
|
|
|
|
|
|
|
* Interface `en1` is unchanged.
|
|
|
|
|
* Primary VLAN `extra` (via its ID `30`) is configured on `en2`.
|
|
|
|
|
* Primary VLAN `extra` (ID `30`) is configured on `en3`.
