NIC Bonding

Submitted by Admin on

NIC bonding (or NIC teaming) is used to aggregate the link to increase the throughput and provide the redundancy. On our Dell servers running Redhat Linux and Centos, we do NIC bonding on the first two embedded NICs: em1 and em2 (read the new Network Interface naming convention).

To enable NIC bonding, first you will need to load the kernel module by creating a file /etc/modprobe.d/bonding.conf

Consistent Network Device Naming

Submitted by Admin on

Traditionally Linux uses name ethX for the network interfaces. Unfortunately, the "X" is non-deterministic and the ethX names have no correlation to the chassis labels. Red Hat Enterprise Linux 6.1 introduces biosdevname, an optional convention for naming network interfaces. biosdevname assigns names to network interfaces based on their physical location.
