Bonding Mode 802.3ad Using 10Gbps Network - Slave NICs Fail to Come Up Consistently after Reboot (Doc ID 1621754.1)

Last updated on JANUARY 29, 2017

Applies to:

Linux OS - Version Oracle Linux 5.5 with Unbreakable Enterprise Kernel [2.6.32] and later
Linux x86-64

Symptoms

On the Oracle Linux system running UEK1/UEK2 kernel, configure a bonding mode 4 (802.3ad) network interface with two 10Gbps NICs (using ixgbe driver) as its slaves.

One of the slave NIC's fails to come up consistently after rebooting the system.

And the output below shows different Aggregator ID for the slave NICs (e.g.  eth5 Aggregator ID is '2' which should be '1').
