MTU is a global setting in Standard or Distributed switches,
cannot be configured per port or port group level.
Sorry my mistake, let me take those statements back which I wrote earlier
Please refer following KB
VMware KB: Enabling Jumbo Frames on virtual distributed switches
It's obvious that you have some of those VMKs with Jumbo frames enabled, let's say you are using VMK to talk to IP Storage where you have enabled Jumbo Frames while another VMK doing FT logging where you have normal MTU of 1500 bytes, I guess it should be OK.
