Overview

This module provides three resource types that can configure most types of interfaces available on Cumulus Linux.

Module Description

The module consists of three resources types:

cumulus_interface

This resource type configures a network interface using ifupdown2. The configuration for the interface is written to a file in the interface configuration file directory. This resource type does not configure VXLAN, bond, or bridge interfaces.

For bridge configuration use the cumulus_bridge module.

For bond configuration use the cumulus_bond module.

cumulus_bond

This resource type configures a network bond using ifupdown2. The configuration for the interface is written to a file in the interface configuration file directory.

cumulus_bridge

This resource type configures a bridge using ifupdown2. The configuration for the interface is written to a file in the interface configuration file directory.

Setup

What cumulus_interface affects

  • This module affects the configuration files located in the interfaces folder and managed by ifupdown2. By default this is /etc/network/interfaces.d.

  • You need to add source /etc/network/interfaces.d/* to /etc/network/interfaces to make use of the new files.

  • To activate the changes, run /sbin/ifreload -a.

NOTE: Reloading the interface configuration is not disruptive if there is no change in the configuration.

Usage

cumulus_interface Examples:

Loopback interface and the management interface eth0 using DHCP:

cumulus_interface { 'lo':
  addr_method => 'loopback',
}

cumulus_interface { 'eth0':
  addr_method => 'dhcp',
}

cumulus_interface { 'eth0':
  ipv4    => ['192.168.0.10/24'],
  gateway => '192.168.0.1',
}

swp33 as a 1GbE port with a single IPv4 address:

cumulus_interface { 'swp33':
  ipv4  => ['10.30.1.1/24'],
  speed => 1000,
}

peerlink.4094, a bond sub-interface, as the CLAG peer interface:

cumulus_interface { 'peerlink.4094':
  ipv4          => ['10.100.1.0/31'],
  clagd_enable  => true,
  clagd_peer_ip => '10.100.1.1/31',
  clagd_sys_mac => '44:38:39:ff:20:94',
}

cumulus_bond Examples:

Bond named peerlink with the interfaces swp1 and swp2 as bond members:

cumulus_bond { 'peerlink':
  slaves => ['swp1-2'],
}

Bond named bond0 with the interfaces swp3 and swp4 as bond members, the minimum link count is set to 2 and the CLAG ID is set:

cumulus_bond { 'bond0':
  slaves    => ['swp3-4'],
  min_links => 2,
  clag_id   => 1,
}

cumulus_bridge Examples:

Default ("traditional") bridge driver:

cumulus_bridge { 'br10':
  ports            => ['swp11-12.1', 'swp32.1'],
  ipv4             => ['10.1.1.1/24', '10.20.1.1/24'],
  ipv6             => ['2001:db8:abcd::/48'],
  alias_name       => 'classic bridge',
  mtu              => 9000,
  mstpctl_treeprio => 4096,
}

VLAN-aware bridge:

cumulus_bridge { 'bridge':
  vlan_aware       => true,
  ports            => ['peerlink', 'downlink', 'swp10'],
  vids             => ['1-4094'],
  pvid             => 1,
  stp              => true,
  mstpctl_treeprio => 4096,
}

  • gateway - String of default gateway to be added with the interface.
  • alias_name - Interface alias.
  • addr_method - Address assignment method, dhcp or loopback. Default is empty (no address method is set).
  • speed - The interface link speed.
  • mtu - The interface Maximum Transmission Unit (MTU).
  • virtual_ip - VRR virtual IP address.
  • virtual_mac - VRR virtual MAC address.
  • vids - Array of VLANs to be configured for a VLAN-aware trunk interface.
  • pvid - Native VLAN for a VLAN-aware trunk interface.
