I'm not totally versed with jumbo frames and gigabit throughput, but as far as I know if you need jumbo frames, it has to be enabled from switchport to switchport for the whole path. 

I noticed that the configuration for gigabit phones have no "jumbo frame" option and I'm not sure if this means that the phone doesn't care if the PC requires jumbo frames and just passes things as is -or- if the phone does not support jumbo frames and will not support a PC with jumbo frames enabled. 

I'm not looking to discuss when/where jumbo frames is required right now, I'm just gonna assume that a client requires it and we can't say no. ;)
