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 linux balance-rr (bond mode=0) work with all switches?

I'm configuring two ethernet interfaces into an aggregation group to double bandwidth, and I was wondering if bond mode=0 works for all switches? What about dumb switches that don't support LACP? Will this methodology double bandwidth for a single…

Server-to-Switch Trunking in Procurve switch, what does this mean?

I am looking to set up switch redundancy in a new datacenter environment. IEEE 802.3ad seems to be the go-to concept on this, at least when paired with a technology that gets around the "single switch" limitation for the link aggregation. Looking…

Network traffic doesn't appear to leave the trunk

I'm in the process of staging up some new virtualization servers, and part of that is to get some higher-bandwidth pipes into them. The ultimate goal is to bind 4 GigE ports into a single trunk carrying 802.1q tagged traffic. I can get that far,…

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…

How to achieve 2-gigabit total throughput on Linux using the bonding driver?

For this application I am less concerned with high availability than I am with total throughput. I have one IP address on the server end, and I want to be able to send more than 1-gigabit of traffic out from the server. The server has two 1-gigabit…
