Description qvlatrt 2011-10-28 12:19:35 UTC 
Description of problem:
Bonding miimon=100 for this ethernet ports is not working.
If I unplugg cable, Link will staid up (MII Status: up)and traffic will be losted.

On another hand, if I configured bonding with arp_interval and arp_ip_target system recognized when cable is unplugged:
cat /proc/net/bonding/bond0 shows that ,MII Status: down
ifconfig -a show that interface is RUNNING - also BUG 
But trafiic will not be losted and stand by ethenret interface will handle it.

After I unplug cable back I will need to wait for more then 5 minutes to link become up - BUG

Vladimir,

I'm going to close this bug for now.  I see that the customer case you opened with support has stalled out and closed already.  Please reopen that customer case once you have the additional information you were working on, and then we (Red Hat) will reopen this bug once we're able to proceed with a solution.

Thanks
Jeremy West
