PIX/FWSM and Jumbo Frames - Possible?

Does anyone know how I might get jumbo (9000 bytes) frames thru my firewall? I need to transfer large data long distances, and jumbo frames are recommended. Can a PIX or FWSM do it?

Re: PIX/FWSM and Jumbo Frames - Possible?

Kind of an interesting question/answer to this one. The PIX 535 can do jumbo frames up to 16K in size with the Livengood GE cards, but it's not officially supported (ie it has been seen to work but we do not test this officially). All you need to do is to set the MTU on the interface in question. The FWSM will do 9K MTU in 2.1 but it has not been extensively tested either. Sorry for the vagueness but this is the best I can do for now.
