Questions tagged [bonding]

"bonding" is the Linux-term for link aggregation.

Cisco terminiolgy is "etherchannel", other vendors may talk about "trunking".

The idea is to use several pyhsical lines in the same (sub)network or VLAN and load-balance the traffic across these lines.

To make it work both "ends" need to use the same LB-mode.

Does bonding 3 1G NICs into one make a 3G NIC?

For example, I have 3 NICs (1GB) and make a bonded NIC. Do I get a 3GB NIC? Should I connect these 3 NICs into 1 switch? If one NIC dies, do I still have the network between server and switch alive? Or should I connect each NIC to 3 different…
