Hi Christian,

Currently, configbond does not support nicextraparams, it is on our
backlog, but may not be high priority.
 If you want to change MTU value, you can add "MTU=9000" before line 200 in
configbond to work around your work, like the following example:

   BONDING_OPTS="${array_bond_opts[*]}"
   MTU=9000
   EOF

Best Regards

I have the following setup:

nodels gss1 nics
gss1: nics.nicips: bond0!10.100.10.20
gss1: nics.nicextraparams: bond0!MTU=9000
gss1: nics.nicsadapter: bond0!MTU=9000
gss1: nics.nichostnamesuffixes: bond0!-10g
gss1: nics.nicdevices:
bond0!enp134s0,enp134s0d1,enp27s0,enp27s0d1,enp32s0,enp32s0d1
gss1: nics.node: gss1
gss1: nics.niccustomscripts: bond0!configbond bond0
enp134s0@enp134s0d1@enp27s0@enp27s0d1@enp32s0@
enp32s0d1 miimon=100@mode=4@xmit_hash_policy=1
gss1: nics.nicnetworks: bond0!10G
gss1: nics.nictypes: bond0!Ethernet

Despite this, the MTU setting isn't being placed in the ifcfg-bond script.

Looking at the nics manpage, it's not really clear which setting does
which:
 nicextraparams
nicextraparams
                 Comma-separated list of extra parameters that will be used
for each NIC configuration.
nicsadapter
                 Comma-separated list of extra parameters that will be used
for each NIC configuration.
