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.
