Hi, Sanity check: Am I correct that enabling jumbo frames on a Gb card makes sense only if there is another Gb card on the other end? That is, if the master has the GigE card, but all the slaves have only 100 Mb cards, jumbo frames will not help or even screw everything up, right? Also, do I have to do anyting to the switch to enable jumbo frame support?
