Bonding Group Settings in IGEL OS 12 | IGEL OS Base System

In IGEL OS 12, you can configure up to 4 bonding groups for network bonding. This article describes the available bonding group settings.

Bonding Group Settings

Bond mode

The following bond modes are available:

Active Backup (Default)
Round Robin (balance-rr)
802.3ad (LACP) (Link Aggregation Control Protocol)
XOR (balance-xor)
TLB (Transmit Load Balancing) (balance-tlb)
ALB (Adaptive Load Balancing) (balance-alb)
Broadcast

Transmit hash policy

This setting is available when you select one of the following bond modes:

802.3ad (LACP)
XOR
TLB

The following options are available:

layer2 (Default)
layer3+4
layer2+3
encap2+3
encap3+4
vlan+srcmac

LACP rate

This option only becomes available when you select the bond mode 802.3ad (LACP).

The following options are available:

slow (30s) (Default)
fast (1s)

Monitoring frequency (ms)

Set the interval between link-monitoring checks. (Default: 100 milliseconds)

For MII bond link monitoring, this sets the MII interval; for ARP bond link monitoring, it sets the ARP interval.

Bond link monitoring

Set the bond link monitoring method. The following options are available:

MII (Media Independent Interface) (Default)
ARP (Address Resolution Protocol)

ARP targets

This setting is available when you select ARP as the Bond link monitoring method.

Enter the IP addresses that the device queries to verify the bond connection. Separate multiple IP addresses with commas.

Link up delay (ms)

This setting only applies when you select MII as the Bond link monitoring method.

Set the delay in milliseconds after link recovery before enabling a slave. (Default: 0) Use a value that is a multiple of the monitoring frequency.

Link down delay (ms)

This setting only applies when you select MII as the Bond link monitoring method.

Set the delay in milliseconds after link failure before disabling a slave. (Default: 0) Use a value that is a mutliple of the monitoring frequency.

Additional Bonding Group Settings in the Registry

There are some network bonding configuration parameters that are only available in the form of registry keys. You can find these registry keys through the search in the configurator with Include Registry enabled. For details, see Registry in IGEL OS 12.

Bond options must be valid together for the selected mode and monitoring method. An incompatible combination can prevent NetworkManager from accepting the connection.

Registry Key	Parameter	Supported Values and Applicability
`network.interfaces.bonding.bond%.fail_over_mac`	Fail-over MAC	Values: `none` (Default), `active`, `follow` Applies to: Active Backup mode
`network.interfaces.bonding.bond%.primary_reselect`	Primary reselect	Values: `always` (Default), `better`, `failure` Applies to Active Backup, TLB, and ALB modes.
`network.interfaces.bonding.bond%.arp_validate`	ARP validate	Values: `none` (Default), `active`, `backup`, `all` Applies to ARP monitoring.
`network.interfaces.bonding.bond%.all_slaves_active`	Deliver traffic on inactive slaves	Values: `false` (Default), `true` If enabled, received frames on inactive slaves are delivered instead of dropped.
`network.interfaces.bonding.bond%.bond_options`	Bond options (fallback)	Enter comma-separated `key=value` options in nmcli bond.options format (e.g. `mode=active-backup,miimon=100,fail_over_mac=active,primary_reselect=always`). This is a catch-all field for additional NetworkManager bond options. When the field is not empty, its options are applied after the individual bond settings. New keys supplement the individual settings, while matching keys override them.
`network.interfaces.bonding.bond%.autoconnect_retries`	Autoconnect retries	Values: `-1` (Default: use the NetworkManager global default), `0` (retry indefinitely), or a positive number of attempts. Applies only to the bond connection.
