NIC Bindings under Linux

The function of NIC binding: 1, redundancy, prevent single point of failure

2. Prevent transmission bottlenecks

1. Switch Port bindings:

1 system-view2 link-aggregation Group 1 mode manual34  For example, to bind ports 1 and 2 56 interface ethernet1/0/1                  # Enter switch 1 port 7 Port Link-aggregation Group 1        # joins the current port into the aggregation Group 18 interface ETHERNET1/0/2                  #  Enter switch 2 port 9 Port link-aggregation Group 1        

2. System NIC Binding

1. Set Boundingvi/etc/modules.conf#Add the following contentalias bond0 bondingoptions bonding mode=1 miimon=200 primary=eth2 use_carrier=12. Load bonding module Modprobe bonding3. Create/Modify bond0 eth0 eth1 configuration file VI/et/sysconfig/network-ifcfg-"NIC name" DEVICE=' bond0 ' Bootproto=' static ' broadcast=' x.x.x.x ' ipaddr=' x.x.x.x ' DEVICE=Eth0bootproto=' static ' STARTMODE=' Onboot ' DEVICE=Eth1bootproto=' static ' STARTMODE=' Onboot '4. Restart all NICs rcnetwork restart5.
