Description Takuma Umeya 2011-02-04 08:48:48 UTC

Description of problem:
The fix for bug #483711 cleans up /sys/class/net/bondX/bonding/arp_ip_target in
ifdown.
When using /etc/modprobe.conf to set the bonding options (and not BONDING_OPTS
in /etc/sysconfig/network-scripts/ifcfg-bond<x>, ie old-style config), then the
interface will not come up after a network restart because the arp_ip_target is
not restored.
BZ604669 takes care of the same issue on RHEL5. 

Version-Release number of selected component (if applicable):
initscripts-9.03.17-1.el6

How reproducible:
Always

Steps to Reproduce:
1. set bonding with a /etc/modprobe.d/bonding.conf file.
alias bond0 bonding
options bond0 mode=1 arp_interval=1000 arp_ip_target=192.168.0.1

2. start network service.
# service network start

3. restart network service.
# service network restart
  
Actual results:
bond0 will never come up because the  arp_ip_target is cleared in ifdown

Expected results:
the arp_ip_target should be restored even when specified in modprobe.conf
