	if you're using a 7200, you likely want to review this
page:

http://www.cisco.com/en/US/products/hw/modules/ps2033/products_field_notice09186a0080094102.shtml


	other caveat: most fddi cards use a mtu of 4470, if you're
doing any other jumbo frames/mtus in your network you may want to
keep an eye out for troubles.
