ISSUE

Ethernet Channel Bonding Driver:v2.6.3-rh (June 8, 2005)

Bonding:Warning:either Miimon or Arp_interval and Arp_ip_target module

Parameters must be specified, otherwise bonding would not detect link failures!

See Bonding.txt for details.

Divert:allocating divert_blk for Bond0

Solution

Properly setup bonding alias in "/etc/modprobe.conf"

# # Setup Bond0 alias and set it ' s option in

# #/etc/modprobe.conf

##

# # Note:

# # MIIMON=100 (msecs) [Media Independent Interface (MII) Link

Monitoring]

# # Mode=1 (Bond mode) ["1" is "active-backup" mode]

##

##

Vi/etc/modprobe.conf

---Add the following to the end of the file---

Alias Bond0 Bonding

Options Bond0 miimon=100 mode=1

[[email protected] log]# grep bond0/etc/modprobe.conf

Alias Bond0 Bonding

Options Bond0 miimon=100 mode=1
