As long as every device has a *bigger* MTU, you're fine and there's no real benefit other than maybe a few wasted cycles in the switch copying the extra 8 bytes when the frame is sent. The killer is if one device has a *smaller* MTU, forcing fragmentation and reassembly. ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
