I have fixed it on his setup, but there is a bug in the MacMap.pm. It assumes interface names will always be like ‘swp33’ or so in cumulus.
However if you use breakout cables from a QSFP switch, for example, it may be: ‘swp33s2’ For example. It seems the ‘namesmatched’ sub was not used and the logic was attempted to be duplicated. I did a quick tweak: https://github.com/jjohnson42/xcat-core/commit/72d68bc7bd21a51aadf0444fede0067670c0b391 To simplify to just take the whole interface name, so long as it at least begins with swp.
