Configure LAGG Interface?

CentOS 7 Comments

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. After quite a bit of searching, I’m not seeing anything of the sort. Is LAGG specific to the BSD world and the HP switches I’m running? Or, does it go by a different name? Bonding perhaps? If so, is bonding compatible with LAGG?

  • 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.

    On FreeBSD, you don’t get 2*1 Gbit from A to B, but 1*1 Gbit from A to B and another 1*1 Gbit from C to B.
    “B” being the server with the LAGG interface.

    How is that in CentOS?

    It is of course the same, as long as we speak about standardized 802.3ad protocol.
