Hello, I am trying to setup a bonded Ethernet interface on a node (xCAT
2.14.6 / RHEL 7.6).

It works almost fine, except for the bonding options which I fail to change.
The default seems to be "802.3ad".
I'd like to set it to "mode=2".

I tried this:

chdef node1 nicextraparams.bond0="BONDING_OPTS=mode=2"

Which seems to be taken into account:

tabdump nics
#node,nicips,nichostnamesuffixes,nichostnameprefixes,nictypes,niccustomscripts,nicnetworks,nicaliases,nicextraparams,nicdevices,nicsadapter,comments,disable
"node1","bond0!172.31.0.11",,,"bond0!bond,enp195s0f1!ethernet,enp195s0f0!ethernet",,"bond0!172_31_0_0-255_255_0_0",,"bond0!BONDING_OPTS=mode=2","bond0!enp195s0f0|enp195s0f1",,,

But when I update the network configuration on the node, the settings is
not applied.

cat /proc/net/bonding/bond0 | grep -i mode
Bonding Mode: IEEE 802.3ad Dynamic link aggregation

What else can I try?

Thanks
