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.

Is Level One's Trunking feature like LAG/Etherchannel or is it used for VLANs?

I have a couple of Level One GSW-2476 switches. They allow setting a port's membership in one of eight trunks. Up until now, I thought of trunking as being like LAG groups, i.e. load balancing/aggregation/redundancy. After configuring some ports to…

Why are there different types of bond configuration policies in linux, instead of one that can give a combined throughput and fail-over configuration?

I am confused and not able to understand exactly the actual concept behind it. At switch level, what happens that prevents to use one globally accepted bond configuration policy? And I don't understand why do we use specifically active-backup…
