It makes sense to adopt the naming practice, to ‘future proof’ a distribution move to an ‘init’ successor such as systemd. Conf are disfavored, in preference to writing, and the initscripts parsing, smaller configuration files that should, but are not yet required, to end in a. D/ and sourced in alphabetical sequence. As time has passed, edits in /etc/modprobe. Those files are placed in: /etc/modprobe.

Presuming that you want two bond interfaces, you must configure /etc/modules. You can use multiple bond interfaces but for that you must load the bonding module as many as there are bond links, possibly with varying options. Conf as follow: alias bond0 bonding options bond0 -o bond0 mode=0 miimon=100 alias bond1 bonding options bond1 -o bond1 mode=1 miimon=100.

Configure NIC bonding in CentOS 7 / RHEL 7. We need to create bond0 configuration file: vim /etc/sysconfig/network-scripts/ifcfg-bond0.

Utilizes all slaves in the active aggregator according to the 802. Creates aggregation groups that share the same speed and duplex settings. 3ad Dynamic link aggregation. Pre-requisites: Ethtool support in the base drivers for retrieving the speed and duplex of each slave. Most switches will require some type of configuration to enable 802. A switch that supports IEEE 802. 3ad Dynamic link aggregation.

If the receiving slave fails, another slave takes over the MAC address of the failed receiving slave. The outgoing traffic is distributed according to the current load (computed relative to the speed) on each slave. Incoming traffic is received by the current slave. Adaptive transmit load balancing: Channel bonding that does not require any special switch support.

The behavior of the bonded interfaces depends upon the mode; generally speaking, modes provide either hot standby or load balancing services. The Linux bonding driver provides a method for combining multiple network interfaces into a single logical “bonded” interface. Linux allows us to bond multiple network interfaces into single interface using a special kernel module named bonding.

It will increase the network throughput, bandwidth and will give redundancy. Network bonding is a method of combining two or more network interfaces together into a single interface. Network bonding can be used in situations wherever you need redundancy, fault tolerance or load balancing networks. If one interface is down or unplugged, the other one will keep the network traffic up and alive.
