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

Warning

When you split ports into four interfaces, you must configure the adjacent port as “disabled” in this file. When splitting a port into two interfaces, such as 2x50G, you do not have to disable the adjacent port. Adjacent ports only need to be disabled when a port is split into four interfaces. For example, when splitting port 1 into four 25G interfaces, port 2 must be configured as “disabled”. For more information, refer to the documentation at https://docs.nvidia.com/networking-ethernet-software/cumulus-linux-42/Layer-1-and-Switch-Ports/Interface-Configuration-and-Management/Switch-Port-Attributes/#breakout-ports

  • disabled: disabled => 'swp3' in conjunction with speed_4_by_10g => 'swp2':
node default {
  cumulus_ports { 'speeds':
    speed_4_by_10g => ["swp2"],
    disabled       => ["swp3"],
  }
}

produces the following text in /etc/cumulus/ports.conf:

swp2=4x10G
swp3=disabled

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.

Development

  1. Fork it.
  2. Create your feature branch (git checkout -b my-new-feature).
  3. Commit your changes (git commit -am 'Add some feature').
  4. Push to the branch (git push origin my-new-feature).
  5. Create new Pull Request.
