Last updated on JULY 24, 2014

Applies to:

Linux OS - Version Oracle Linux 5.4 and later
Information in this document applies to any platform.

Symptoms

On Oracle Linux systems, bonding eth0 and eth1 as bond0(mode=1), delay comes when doing 'ifup eth[0-1]' on a bond0.
Problem appears at the ifup eth[0-1]. E.g.:

# ifdown eth0 <-- OK
# ifup eth0 <-- OK
# ifdown eth1 <-- OK
# ifup eth1 <-- OK
# ifdown eth0 <-- OK
# ifup eth0 <-- hangs for few seconds, 7 package was lost at ping

During executed above commands, ping from the host, found some packets lost(7-20).
