Hi All,
I have done IEEE 802.3ad Dynamic link aggregation bond configuration with name bond0 which has 4 slaves (each 25GB/s) in it on cent os 6.8. Issue i am facing is bonding throughput is only 50GB/s not 100GB/s. below are the configuration files :
DEVICE=bond0
IPADDR=xx.xx.xx.xx
NETMASK=yyy.yyy.yyy.yyy
GATEWAY=zz.zz.zz.zz
USERCTL=no
BOOTPROTO=none
ONBOOT=yes
BONDING_OPTS="mode=4 miimon=100 xmit_hash_policy=1"
MTU=9000
IPV6INIT=yes
IPV6ADDR=xxxx:xxxx:xxxx:xxxx:xxxx
#IPV6_DEFAULTGW=yyyy:yyyy:yyyy:yyyy
NM_CONTROLLED=no

also below is the output of /proc/net/bonding/bond0 which shows number of ports only 2 not 4 :

also while making bond up i am getting below error :
# ifup bond0
Device eth1 has different MAC address than expected, ignoring.
Unable to start slave device ifcfg-eth1 for master bond0.
Device eth2 has different MAC address than expected, ignoring.
Unable to start slave device ifcfg-eth2 for master bond0.
Device eth3 has different MAC address than expected, ignoring.
Unable to start slave device ifcfg-eth3 for master bond0.
Please suggest to find out the root cause of it.
