_ALL_ devices on a layer-2 fabric need to have the same MTU. That means if there are any FastEthernet or Ethernet connected members 1500 bytes is it. It also means if you pick a larger value (4470, 9k) _ALL_ members must use the same value.
Only devices exchanging frames with each other need have the same MTU. One could easily imagine one 802.1q VLAN with MTU N and a different 802.1q VLAN with MTU Y all on the same switch, to give a trivial example. Some exchanges already use VLANs with their GigE switches for a variety of business reasons. Ran rja () inet org
