Hi Friend,
FDDI ports support ISL trunking as in ISL header there is a TYPE feild and if the TYPE CODE is "0010" it is for FDDI and if it is "0000" it is for ethernet.
Dot1q on cisco switches in only for fast ethernet or gigabit ethernet I believe. I do not see any feild in dot1q header which can differentiate ethernet frame from fddi frame.

Hi!
FDDI ports support only 802.10 encapsulation.
Here is a link which would help you in configuring a trunk link on a FDDI port.
Hope it helps.
