Its a bit like "The brakes are a bit odd >but I use the handbrake when driving instead" 8) This is a note from the MP3000 SAPR guide (sa99-002-101) The 1492 limit is an OS/2 driver (LAPS) limitation of the 7060. Note: Because LCS3172 uses LANDD (LAPS) to transmit the frames, the 1492 byte maximum applies to both DIX and IEEE 802.3 frames (since LAPS accepts frames for transmission in only one format (IEEE 802.3) and 8 bytes are lost in the conversion process). Since LCS3172 is just part of the IP network, frames larger than 1492 bytes wont be transmitted and no one can be notified that this has happened. Bob.
