In my experience, LAG/LACP won't provide aggregatation, only failover and fault tolerance. For link aggregation, you don't need to configure the switch ports - just set bonding to mode=6 for balanced transmit/receive and plug up the the NICs to a group of ports on the switch. However, balance-alb doesn't help with single stream rsync/FTP sessions, etc, but helps a lot with concurrent transmits/receives as encountered in typical fileserver scenarios. - c On 06/08/12 17:00, centos-request at centos.org wrote: > Message: 30 > Date: Mon, 06 Aug 2012 13:56:41 +0100 > From: Giles Coochey <giles at coochey.net> > Subject: Re: [CentOS] Configure LAGG Interface? > To: centos at centos.org > Message-ID: <501FBF09.5080206 at coochey.net> > Content-Type: text/plain; charset="iso-8859-1" > > On 02/08/2012 02:00, Tim Nelson wrote: >> > ----- Original Message ----- >>> >> On 01.08.2012 21:17, Tim Nelson wrote: >>>> >>> Greetings- I'd like to configure multiple copper NICs on a server >>>> >>> running CentOS 6.2 in a LAGG configuration for better throughput to >>>> >>> the core switch.
