Can you expand on why? For example I definitely can send to the same MLID with different SLs. Of course MTU and rate need to match up but I don't see that as a real restriction -- the SM needs to allows for least-common-denominator values anyway, since the least-capable node on the fabric might join an existing group. I don't see why one MCG with an MTU of 2048 and one MCG with an MTU of 1024 can't share the same MLID, as long as the underlying fabric is capable of supporting an MTU of 2048. Actually, I wonder what the spec says about what switches should do if they're asked to forward packets with too-big MTUs? Maybe it all works out anyway. - R. _______________________________________________ openib-general mailing list openib-general@openib.org http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
