Can people who are currently using these boxes please send me their evaluations: I am most interested in how well it handles Tcp/Ip protocols and how transparently it passes Decnet traffic. Please reply directly to me and not to the list. Thanks, Hank

Could some kind soul please refresh my memory on the loopback packet sent by Proteon p4200 gateways? As I remember, this packet contains an intentional CRC error. At what rate are these sent? Our p4200 is sending ethernet packets which have *both* the source and destination ethernet address set to 02:07:01:00:00:00 (notice all the zeros). Is this "normal"??? The ethernet address of the associated interface is supposed to be 02:07:01:01:BF:15. (Could it be that the interface is. . . . broken?!? :-) Thanks in advance, Walt Wimer Networking and Communications Carnegie Mellon University

(Could it be that the interface is. . >. . broken?!? :-) The p4200 issues two test packets every four seconds to the address you have listed. Both packets contain identical information (I don't know what it is) but the first one is intentionally misaligned (not a crc error). The second packet is good. SO, no, your interface is not broken. The biggest complaint I have about these test packets is that with some systems, the misaligned packet shows up as a crc error, and you have to keep this in mind if you are using this system to check for errors on the network. (the two packets are issued a few microseconds apart). Hope this answers your questions. Michael Pare, P. Eng. Woods Hole Oceanographic Institution Woods Hole, MA
