value is set to 0 by default, which disables it.• updelay= — Specifies (in milliseconds) how long to wait before enabling a link. The valuemust be a multiple of the value specified in the miimon parameter. The value is set to 0 bydefault, which disables it.• arp_interval= — Specifies (in milliseconds) how often ARP monitoring occurs.If using this setting while in mode0 or 2 (the two load-balancing modes), the network switchmust be configured to distribute packets evenly across the NICs. For more information onhow to accomplish this, refer to/usr/share/doc/kernel-doc-/Documentation/networking/bonding.txtThe value is set to 0 by default, which disables it.• arp_ip_target= — Specifies the target IP address of ARP requests when the arp_intervalparameter is enabled. Up to 16 IP addresses can be specified in a comma separated list.• primary= — Specifies the interface name, such as eth0, of the primary device. The primarydevice is the first of the bonding interfaces to be used and is not abandoned unless it fails.This setting is particularly useful when one NIC in the bonding interface is faster and,therefore, able to handle a bigger load.This setting is only valid when the bonding interface is in active-backup mode. Refer to/usr/share/doc/kernel-doc-/Documentation/networking/bonding.txtfor more information.• multicast= — Specifies an integer value for the type of multicast support desired.Acceptable values for this parameter are:0 — Disables multicast support.1 — Enables multicast support, but only on the active slave.2 — Enables multicast support on all slaves (the default).ImportantIt is essential that either the arp_interval and arp_ip_target or miimonparameters are specified. Failure to due so can cause degradation of networkperformance in the event a link fails.Refer to the following file for more information (note that you must have the kernel-docThe Channel Bonding Module393
