Hi Roosen,
Thanks your information.
Could you find `bond0!BONDING_OPTS=mode=2` in output of updatenode?
Do you find `BONDING_OPTS="mode=2"` from ifcfg-bond0 after updatenode command?
I cannot reproduce this issue in my RH7.6 environment, I tried the command `chdef node1 nicextraparams.bond0="BONDING_OPTS=mode=2"` and `updatenode node1 confignetwork`, it worked.
"802.3ad" is the default value for BONDING_OPTS in our code /install/postscripts/nicutils.sh, You can replace line _bonding_opts="mode=802.3ad miimon=100" with _bonding_opts="mode=2" in our code /install/postscripts/nicutils.sh, then try to run "updatenode node1 confignetwork" to see if it work or not.
Best Regards

It works fine when I re-install the node.
