Overview

This Puppet module provides a simple interface for managing initial port configuration on Cumulus Linux.

Module Description

The cumulus_ports module is responsible for setting the initial speed of a 10G or 40G port. On some bare metal switches, it is possible to take a 40G port and split it up into four 10G ports using a breakout cable. For more details, read the Cumulus Linux User Guide and search for "Switch Port Attributes".

Setup

What cumulus_ports affects

This module affects the /etc/cumulus/ports.conf file.
To activate the changes in the file, the switchd daemon must be restarted.

NOTE: Restarting the switchd daemon is disruptive.

Beginning with cumulus_ports

This module does not use any default parameters. Support for default parameters is on the roadmap.

Usage

The module currently supports one define, cumulus_ports::speeds:

node default {
  cumulus_ports { 'speeds':
    speed_40g_div_4 => ["swp1-4"],
    speed_10g => ["swp5-48"],
    speed_4_by_10g => ["swp49-50"],
    speed_40g => ["swp51-52"]
  }
}

Reference

###Types

####cumulus_ports

Generates a custom /etc/cumulus/ports.conf based on the following variables:

speed_10g: speed_10g => 'swp1-2' produces the following text in /etc/cumulus/ports.conf:
```
swp1=10G
swp2=10G
```
speed_40g : speed_40g => 'swp1-2' produces the following text in /etc/cumulus/ports.conf:
```
swp1=40G
swp2=40G
```
speed_40g_div_4: speed_40g_div_4 => ['swp1', 'swp4'] produces the following text in /etc/cumulus/ports.conf:
```
swp1=40/4
swp4=40/4
```
speed_4_by_10g: speed_4_by_10g => 'swp1-2' produces the following text in /etc/cumulus/ports.conf:
```
swp1=4x10G
swp2=4x10G
```

Limitations

This module only works on Cumulus Linux.

The module does not currently do any error checking. Ensure that the whole configuration is thoroughly tested, or the switch can behave in unpredictable ways.

puppet resource cumulus_ports doesn't currently work. This will be implemented in a later version.
