| - | Le **bonding** sous Linux c'est un agrégat de ports, c'est-à-dire l'association logique de plusieurs interfaces réseau physiques pour en créer une logique, plus rapide et/ou plus fiable. C'est l'équivalent de l'//etherchannel// en terminologie Cisco ou du //sharing// chez Extreme Networks. Sous Linux on utilise souvent le protocole LACP (802.3ad) pour grouper ces interfaces entre elles et dialoguer avec l'équipement d'en face. | + | |

| - | =====Configuration sous centOS===== | + | |
| - | + | ||
| - | Fichiers de configuration : | + | |
| - | * sous Debian/Ubuntu : ''/etc/network/interfaces'' | + | |
| - | * sous Redhat/CentOS : ''/etc/sysconfig/network/ifcfg-bond0'' | + | |
| - | + | ||
| - | Pour fonctionner, on doit disposer de une ou plusieurs interfaces physiques similaires en terme de type et de débit. Par exemple eth2 et eth3 : | + | |
| - | <code bash> | + | |
| - | # eth2 | + | |
| - | DEVICE=eth2 | + | |
| - | BOOTPROTO=none | + | |
| - | ONBOOT=yes | + | |
| - | HWADDR=00:e0:ed:xx:xx:x2 | + | |
| - | MASTER=bond0 | + | |
| - | SLAVE=yes | + | |
| - | TYPE=Ethernet | + | |
| - | USERCTL=no | + | |
| - | + | ||
| - | # eth3 | + | |
| - | DEVICE=eth3 | + | |
| - | BOOTPROTO=none | + | |
| - | ONBOOT=yes | + | |
| - | HWADDR=00:e0:ed:xx:xx:x3 | + | |
| - | MASTER=bond0 | + | |
| - | SLAVE=yes | + | |
| - | TYPE=Ethernet | + | |
| - | USERCTL=no | + | |
| - | </code> | + | |
