Linux bond or team multiple network interfaces (NIC) into single interfaceQuota InstallationLinux allows binding multiple network interfaces into a single channel/NIC using special kernel module called bonding. According to official bonding documentation, "The Linux bonding driver provides a method for aggregating multiple network interfaces into a single logical "bonded" interface. The behavior of the bonded interfaces depends upon the mode; generally speaking, modes provide either hot standby or load balancing services. Additionally, link integrity monitoring may be performed."
[root@local~]# vi /etc/sysconfig/network-scripts/ifcfg-bond0
[root@local~]# vi /etc/sysconfig/network-scripts/ifcfg-eth0
[root@local~]# vi /etc/sysconfig/network-scripts/ifcfg-eth1
[root@local~]# vi /etc/modprobe.conf
mode= Specifies one of four policies allowed for the bonding module. Acceptable values for this parameter are:
0 Sets a round-robin policy for fault tolerance and load balancing. Transmissions are received and sent out sequentially on each bonded slave interface beginning with the first one available.
1 Sets an active-backup policy for fault tolerance. Transmissions are received and sent out via the first available bonded slave interface. Another bonded slave interface is only used if the active bonded slave interface fails.
2 Sets an XOR (exclusive-or) policy for fault tolerance and load balancing. Using this method, the interface matches up the incoming request's MAC address with the MAC address for one of the slave NICs. Once this link is established, transmissions are sent out sequentially beginning with the first available interface.
3 Sets a broadcast policy for fault tolerance. All transmissions are sent on all slave interfaces.
4 Sets an IEEE 802.3ad dynamic link aggregation policy. Creates aggregation groups that share the same speed and duplex settings. Transmits and receives on all slaves in the active aggregator. Requires a switch that is 802.3ad compliant.
5 Sets a Transmit Load Balancing (TLB) policy for fault tolerance and load balancing. The outgoing traffic is distributed according to the current load on each slave interface. Incoming traffic is received by the current slave. If the receiving slave fails, another slave takes over the MAC address of the failed slave.
6 Sets an Active Load Balancing (ALB) policy for fault tolerance and load balancing. Includes transmit and receive load balancing for IPV4 traffic. Receive load balancing is achieved through ARP negotiation.
