Hi Chris,
We had a contribution from the community that added support for this late last year to add support for MTU on the networks table.
https://github.com/xcat2/xcat-core/pull/1933 Looks like it was integrated in the 2.12.4 release or newer.
I'm not sure which version of xCAT you are currently on, but you can take a look at that pull request and see if it satisfies your requirements.
Thanks,
Victor

Subject: [xcat-user] Setting MTU
Date: Tue, Feb 21, 2017 6:30 AM
I'm trying to configure the MTU to be 9000 for Centos 7 hosts on our
internal network. I'm using xCAT 2.12.4
A way that works is to set the MTU explicitly on a network card basis -
so I do:
nicextraparams.ens1f0=MTU=9000
and add
"confignics -s"
to the postscripts for the node.
However we have a number of different hardware types - and the internal
network card name therefore changes.
It seems cleaner to set the MTU in the MTU column of the networks table,
instead of explicitly listing each network card type. For testing, I've
removed the "nicextraparams.ens1f0=MTU=9000" and set the MTU of 9000 in
the networks table. DHCP now correctly sets the MTU to be 9000, but this
is then removed by "confignics -s" - resulting in the default of 1500
after install.
Is this an oversight on my part, or a bug in confignics, or configeth
Chris
