Mixing Jumbo Frames?
Posted on 2004-09-21
The last few computers I've acquired have come with gigabit ethernet NICs as part of the package. Since I'm constantly transferring large files around my home LAN, and am a bit of a networking buff, I've decided to buy a gigabit ethernet switch. I've decided on the SMC8508T to serve my purposes, which supports jumbo frames. I'm familiar with the concept of jumbo frames, but this will be my first experience with their implementation. My question is, is it possible to mix 10/100 network devices with gigabit devices using jumbo frames over the same layer 2 media? For example, if I have two gigabit desktops with jumbo frames enabled, and one 10/100 desktop (running at 100 full) all connected to my switch, will they all communicate properly? Or is it necessary to have a layer three router separating the jumbo from the standard? Thanks.
