Does anyone know of any literature which exist giving a FDDI ring verification plan? What I am looking for is not necessarily a protocol conformance, but more of a general discussion about how to verify that a FDDI ring is operating properly. Things like what happens if T_MIN of a station is greater than T_NEG after the claim process? Also maybe a general plan to test the interoperations of the functions described in the FDDI standards. Thanks for any references, Bob McMahon rmcmahon@houvmscc.iinus1.ibm.com

If I remember correctly, a draft was proposed. (Well, I did not attend that working group because I was in the fun one -- SMT!, therefore, I might be wrong.) In addition to the ANSI, the Univ of New Hamspire(sp?) has a FDDI Interoperability Test Suite. I don't know what you can get from them but I think that around 26 companies were involved and they went through a series of tests last Dec. Last is the AMD ANTC test center. I think that it is basically an advertizing thing, so I don't think that they are doing much. Anyway, if you have a FDDI ring and stations running SMT 6.2, you can probably run a FDDI network manager program to collect SMT messages on the ring and find out what the status of the ring. Also just looking at the ring map and the number of Ring_Non_Op will tell you if the ring is connected. -- Mike my@berlioz.nsc.com
