hey matt

you definitely know more than me on this, but i just want to clarify what you wrote. the switch just has jumbo frames enabled or not. you don't set the size on the switch. i think they support packets over 9000. i also believe that all switches you guys ship have Jumbo enabled by default, which wasnt always the case. since having it on causes no harm to standard 1500 byte packets.

jacob,

the important setting is at the computer and server. 8100 is a magical number for packet efficiency. Steve at Small Tree can go into this further. but you need to have the computer and server use the same setting, otherwise you could get dropped packets. every computer you have hooked into this switch (or at least in this VLAN) must have Jumbo frames turned on and set to 8100.
